It has been.

  The lot information includes the product name, the number of orders, the number of manufacturing, the delivery date, and the like. When a product is repeatedly produced, different lot information exists for the same product. The product process master includes, for example, all the manufacturing processes and members necessary for production, the order of performing each manufacturing process, and the time required for each manufacturing process per unit product (“ Setup time ”and“ Standard time ”), and a bill of materials (unit price, number of uses, etc.) of each member used. Furthermore, the production processing information includes information on the machine equipment used in each manufacturing process and the worker in charge.

  Further, the control means 101 here receives an operation input from the input means 104, and writes lot information into the lot information storage unit 121, lot information registration means 151, and each manufacturing process related to the new lot information Gantt chart generating means 152 for generating each Gantt bar on the lot-specific Gantt chart displayed on the display means 105, each manufacturing process of lot information stored in the production information storage section 123, and machine equipment information storage section The process-machine allocation means 153 that identifies the machine equipment to be used for each manufacturing process of each lot information from the operation status of the available machine equipment stored in 124, and the lot information stored in the production information storage unit 123 Process-worker assigning means 1 for identifying the worker in charge for each manufacturing process of each lot information from each manufacturing process and the operation status of the workable worker stored in the worker information storage unit 125 54, a member ordering means 155 that outputs a list of parts required for a lot product, and a work information management means 156 that outputs a lot work instruction and makes it possible to collect and view lot work results. I have.

  Hereinafter, with respect to the business screen 2 displayed on the display means 105, referring to FIG. 2 to FIG. 24 showing examples of screens actually displayed on the display means, together with details of each screen constituting the business screen 2, production The operation procedure for performing management work will be described.

  1 Register new order lots according to customer orders.

  The “add lot” menu is selected by the input means 104 (FIG. 2). As a result, the production management program 1 activates the lot information registration means 151.

  The lot information registration means 151 displays the “Add lot information” screen as the lot registration and detailed information screen 26. Therefore, the input means 104 is used to enter, for example, the delivery destination (customer) in the input box 40 of the screen. First, lot information regarding individual parts such as product name, number of orders received, number of products manufactured, and delivery date is input (FIG. 3). The product name is selected from the item selection list, and all manufacturing processes corresponding to the product name are displayed in the rectangular area 41. The manufacturing process displayed in the rectangular area 41 is registered in advance as a manufacturing process master in the manufacturing process master storage unit 122 of the external database 4 in association with the product name. The input new lot information is stored in the lot information storage unit 121.

  Next, the lot information registration unit 151 adds an order lot line relating to the new lot information to the Gantt chart of the production plan chart 11 (FIG. 4). The order lot line includes an item information display column 42 arranged on the left side and a Gantt chart display column 43 arranged on the right side. In the item information display field 42, information corresponding to the schedule displayed in the Gantt chart display field 43 is displayed. Here, among the lot information input at the time of the above-mentioned lot registration, the product name, the number of orders, and the delivery date are displayed. Is displayed. The item information display column 42 is preferably color-coded according to the process progress status of the corresponding lot included in the lot information, for example, pink is undecided, blue is not started, yellow is in progress, The green color may be completed. Thus, if the item information display field 42 is viewed, the process progress status of the lot can be grasped at a glance without looking at the result display in the Gantt chart display field 43. In the Gantt chart display field 43, date and time are assigned to the horizontal axis, and a process Gantt bar 44 in which the length with respect to the horizontal axis indicates the time width of the work required for each manufacturing process is arranged. The time width of the work is made possible by reading the time required for each product process per unit number related to the product from the product process master stored in the product process master storage unit 122.

  2 Create a lot process plan for the added order lot.

  Using the input means 104, the “assign process from end point” menu is selected in the production plan chart 11 (FIG. 5). As a result, the production management program 1 activates the Gantt chart generating means 152.

  Here, when the pointer on the Gantt chart display field 43 displayed on the display unit 105 is appropriately moved by the input unit 104 and clicked with the mouse, the Gantt chart generating unit 152 sets the point clicked by the mouse as the end point. Then, a process Gantt bar 44 indicating the manufacturing process of the lot is allocated and displayed in the Gantt chart display field 43 (FIG. 6). At this time, the Gantt chart generating means 152 automatically generates the process Gantt bar 44 (44a to 44g) for the manufacturing process corresponding to the order lot line (7 processes in the case of FIG. 6). The working time of each manufacturing process, that is, the length of the process gantt bars 44a to 44g, is set by integrating the "setup time" and "standard time" per unit product registered in the product process master in advance and the number of orders. The Accordingly, the automatically generated process gantry bar 44 can be used without being adjusted. Note that when the “assign process from start point” menu shown in FIG. 5 is selected by the input means 104, it is also possible to assign the process by designating the start point.

  The process Gantt bar 44 arranged in the Gantt chart display field 43 is dragged with the mouse as the input means 104 so that all processes are completed before the delivery date display 45 (left side), and the position thereof is adjusted (FIG. 7). ). At this time, not only the Gantt bar related to the dragged process but also the Gantt bars related to the preceding and following processes are moved in the time axis direction by a ball so that the order of the manufacturing processes included in the product process master does not change. For example, the length of the process Gantt bar 44 can be adjusted by dragging with the mouse according to the performance of the mechanical equipment stored in the mechanical equipment information storage unit 124 and the skill of the worker stored in the worker information storage unit 125. It is also possible to do. It should be noted that the area of the Gantt chart display field 43 may be displayed in different colors depending on whether it is within working hours or outside working hours, based on information related to daily working hours stored in advance in the external database 4, and the process Gantt bar 44 is displayed outside working hours. If it is set, a part of the process Gantt bar 44 corresponding to the amount set in the non-working time area may be carried over within the working hours of the next day by dragging the mouse. In this way, it is possible to plan the production process in a form that conforms to the factory working pattern.

  3. Decide which machine equipment to use for each production process of a lot (assign machines to the process).

  (1) A method of assigning by dragging and dropping to a machine-specific Gantt chart.

  By using the input means 104, the “display by lot + display by machine” menu is selected (FIG. 8). As a result, the production management program 1 activates the process-machine allocation means 153.

  The process-machine allocating means 153 divides the window into two parts, and the production plan chart 11 displaying “Gantt chart by lot” on the top and the machine plan chart 12 displaying “Gantt chart by machine” below are the same. It is displayed on the display screen 105 (FIG. 9). The machine plan chart 12 has the same configuration as the production plan chart 11. More specifically, it is composed of a table in which a plurality of machine equipment rows are arranged vertically, each of which is composed of an item information display column 46 arranged on the left side and a Gantt chart display column 47 arranged on the right side. In the item information display field 46, information corresponding to the schedule displayed in the Gantt chart display field 47 is displayed. Here, the machine equipment registered in the machine equipment information storage unit 124 of the external database 4 from the machine registration screen 24 in advance. Information is displayed. In the Gantt chart display field 47, the date and time is assigned to the horizontal axis, and a process Gantt bar 44 in which the length with respect to the horizontal axis indicates the time width of the work required for each manufacturing process is arranged. Note that the manufacturing plan chart 11 and the machine plan chart 12 that are displayed separately in the vertical direction can be linked by the operation of the input means 104, and either of the Gantt chart display fields 43 and 47 can be scrolled horizontally, Scroll simultaneously in upper and lower windows.

  Here, the process Gantt bar 44 on the production plan chart 11 is dragged and dropped on the machine plan chart 12 to the machine facility performing the process work by the input means 104, and the machine is assigned to each production process. In this figure, the process Gantt bar 44a corresponding to the “Blank” process in the Gantt chart display field 43 of the production plan chart 11 is operated on the “Press 80t” machine on November 24, and the Gantt chart of the machine plan chart 12 is used. Drag and drop to the display field 43. At that time, in order to prevent erroneous assignment, the process can be assigned only to machines capable of working. Specifically, for example, according to the manufacturing process of the process Gantt bar 44 of the selected manufacturing plan chart 11, only the machine corresponding to the manufacturing process is selectively displayed on the machine plan chart 12, or corresponds to the manufacturing process. The machine to be operated is highlighted, and assignment to a machine that cannot be operated is prohibited. This can be realized by the process-machine allocating means 153 extracting usable machine equipment from the machine equipment information storage unit 124 on the condition that the designated process gantry bar 44 is manufactured.

  When the target process Gantt bar 44 is dragged and dropped with the input means 104, the process-machine allocation means 153 can use the machine equipment corresponding to the Gantt chart display column 43 of the operation destination, and Whether the machine is operable in the time zone is determined by reading the machine facility information stored in the machine facility information storage unit 124. If it is a machine facility that can be used and can be operated in that time zone, the machine allocation by the process-machine allocation means 153 is performed, and the same process as the Gantt chart display column 43 of the manufacturing plan chart 11 is performed. The Gantt bar 44a is duplicated and displayed in the Gantt chart display field 47 of the machine plan chart 12. In addition, with respect to the machine equipment, the operation rate of the replicated process gantry bar 44a in the time zone is calculated, and the machine equipment information including the operation rate is combined with the machine equipment information storage unit 124 in the manufacturing process of the product related to the process gantt bar 44a. The machine equipment to be used is specified, and the production processing information relating the manufacturing process of the product and the machine equipment to be used is rewritten and updated in the production information storage unit 123. Then, the outline of the process Gantt bar 44a in the production plan chart 11 for which the machine assignment is completed changes from a dotted line indicating unassignment to a solid line. Of course, any display format indicating the allocation state may be used. In this way, by simply dragging and dropping the process Gantt bar 44 on the production plan chart 11 onto the machine plan chart 12, the machine can be easily assigned to each production process.

  The process gantt bar 44 is associated with each belonging to the same lot on the machine plan chart 12, and the connection between the gantt bars constituting the process gantt bar 44 can also be displayed as a connection line. This actual example will be described later.

  If the machine process chart (process gantt bar 44) is assigned to a date and time different from the production plan chart 11 in the machine plan chart 12 (Fig. 10), the process gantt bar 44 of the production plan chart 11 will move accordingly, and the front and rear process gantt bars 44 will also be struck Move (FIG. 11). 10 and 11, the machine plan chart 12 is set so that the process Gantt bar 44b corresponding to the “bend” process in the Gantt chart display field 43 of the production plan chart 11 is operated on the “press 80t” machine on November 28. Is dragged and dropped to the Gantt chart display field 43. Accordingly, in the manufacturing plan chart 11, the "bend" process (process gantt bar 44b) moves on November 28, and the subsequent process gantt bars 44c to 44g also move by ball so that the order of each process does not change. To do. Thus, when the machine allocation by the process-machine allocation means 153 is performed, the required start time and end time of the manufacturing process are specified for each lot information. Such start time and end time are rewritten and updated in the production information storage unit 123 as part of the production processing information.

  In addition, when one manufacturing process can be performed in parallel using a plurality of machines, the process gantt bar 44 can be divided and allocated to a plurality of machine equipment rows. This actual example will also be described later.

  (2) Method of assigning by dragging and dropping to the machine load status table.

  While the production plan chart 11 is displayed on the display means 105, the “load status for each machine” menu is selected by the input means 104 (FIG. 12). As a result, the production management program 1 activates the process-machine allocation means 153.

  Then, the process-machine allocation means 153 causes the same display means 105 to display the machine load status table 13 in a separate window below the manufacturing plan chart 11 (FIG. 13). The machine load status table 13 is composed of a table in which a plurality of machine equipment rows each composed of an item information display column 48 arranged on the left side and a load status display column 49 arranged on the right side are arranged vertically. In the item information display column 48, information corresponding to the schedule displayed in the load status display column 49 is displayed. Here, the machine facility information similar to the machine plan chart 12 is displayed. In the load status display column 49, a plurality of cells are arranged in parallel for each day, and the daily load status of the mechanical equipment is displayed in a bar graph in the cells. This load status can be displayed by the process-machine allocation means 153 reading out the capability and operating status of each mechanical facility included in the mechanical facility information from the mechanical facility information storage unit 124.

  50 is an overload caution line. This is because the process-machine allocation means 153 reads out the operation rate of machine equipment per unit time included in the machine facility information in advance, and how much this operation rate is set to the preset threshold value. It is displayed on the display means 105 by calculating whether it has exceeded. This overload attention line is provided in accordance with a predetermined load serving as a threshold, and when the bar graph exceeds the overload attention line 50, for example, the display color changes to red or the like for the excess amount, for example, to call attention. . Of course, the load status display format may be any format such as a numerical display in percentage. By displaying the load status of the mechanical equipment when assigning the process to the mechanical equipment, the mechanical equipment can be used effectively. The process-machine allocating unit 153 may rearrange the machine equipment rows in order from the machine equipment having a low operation rate (low load) and display the rows on the display means 105 in that order.

  The process Gantt bar 44 of the target production plan chart 11 is dragged and dropped to an empty machine / date cell (load status display column 49) of the machine load status table 13 by the input means 104. In the figure, the process Gantt bar 44a corresponding to the “Blank” process in the Gantt chart display field 43 of the production plan chart 11 is assigned to the November 21 cell of the “Press 80t” machine. Then, the process-machine allocation means 153 reads the availability of the machine equipment on the same day from the machine equipment information stored in the machine equipment information storage unit 124 for the previous machine equipment that has been dragged and dropped. If the machine facility is free for one day, the process gantt bar 44a is assigned from the predetermined start time of the day, and if the reservation is made in advance, the process gantt bar 44a is automatically set at the vacant time. Is assigned. When such allocation is performed, the process-machine allocation unit 153 duplicates and displays the same process Gantt bar 44a as the Gantt chart display field 43 of the manufacturing plan chart 11 also in the Gantt chart display field 47 of the machine plan chart 12. When the process-machine allocation means 153 determines that the operation rate exceeds the overload caution line 50 in the operation time zone by the allocation of the process gantry bar 44a, the excess is vacant after the next day. It is also possible to divide the process gantt bar 44a in terms of time and automatically assign a plurality of process gantt bars 44a. Of course, the machine stored in the machine facility information storage unit 124 specifies that the work time is designated before the assignment by the input means 104, and the previous machine equipment that has been dragged and dropped during the work time is vacant. If it judges from equipment information, you may allocate process Gantt bar 44a to the work time zone about the machine equipment concerned.

  The process gantt bar 44 is assigned to the dropped machine / date, the load (operation rate) of the machine / date to which the process gantt bar 44 is assigned increases, and the assignment result is reflected in the manufacturing plan chart 11 and the machine plan chart 12 ( FIG. 14). Also in this case, with respect to the assigned machine equipment, the operation rate of the duplicated process gantry bar 44a is calculated in time, and the machine facility information including the operation rate is stored together with the machine facility information storage unit 124 in the product related to the process gantt bar 44a. In the manufacturing process, the machine equipment to be used is specified, and the production process information relating the product manufacturing process and the machine equipment to be used is rewritten and updated in the production information storage unit 123.

  4. Decide which worker will work for each manufacturing process in the lot (assign workers to the process).

  In the same manner as the machine assignment in the previous section, the process-worker assignment means 154 instead of the process-machine assignment means 153 assigns workers for each manufacturing process (FIG. 15). In other words, instead of the machine plan chart 12, the worker plan chart 14 is displayed as "Gantt chart by worker", and instead of the machine load situation table 13, the worker load situation table 15 is used. This is substantially the same as the description corresponding to FIGS.

  In FIG. 8, the “display by lot + display by worker” menu is selected by the input means 104. As a result, the production management program 1 activates the process-worker assignment means 154.

  The worker plan chart 14 displayed on the display means 105 by the process-worker assigning means 154 has the same configuration as the machine plan chart 12, and includes an item information display column 51 arranged on the left side and a right side. And a Gantt chart display field 52 arranged in a table composed of a plurality of worker rows arranged vertically. In the item information display column 51, information corresponding to the schedule displayed in the Gantt chart display column 52 is displayed. Here, the worker registered in the worker information storage unit 125 of the external database 4 from the worker registration screen 27 in advance. Information is displayed. The worker load situation table 15 includes a table in which a plurality of worker rows are arranged vertically, each of which includes an item information display column 53 arranged on the left side and a load situation display column 54 arranged on the right side. . In the item information display column 53, information corresponding to the schedule displayed in the load status display column 54 is displayed. Here, worker information similar to the worker plan chart 14 is displayed. The production plan chart 11 and the worker plan chart 14 displayed separately in the vertical direction can be linked by the operation of the input means 104, so that either the Gantt chart display field 43 or 52 can be scrolled horizontally. Scrolls simultaneously in other windows.

  If a plurality of manufacturing processes overlaps the same mechanical equipment or operator during the process planning by drag and drop operation of the process gantry bar 44 by the input means 104, the process-machine allocation means 153 and the process-operator allocation The means 154 displays a warning on the process plan table by the display means 105 (FIG. 16). In the figure, “Draw” process Gantt bar 60 and “Blank” process Gantt bar 61 of different products are assigned to the same “Press 80t” machine, and from 11:00 to 15:00 on November 27 Two manufacturing processes overlap. In this way, when manufacturing process plans using the same mechanical equipment are overlapped, for example, the Gantt chart display field 47 for changing the background color to pink (in the case of the worker plan chart 14, the Gantt chart) A warning is notified by highlighting the corresponding portion of the display column 52) and the alarm number display 62.

  When a specific cell in the warning item row is clicked with the input means 104 in a state where the warning list 65 is displayed on the warning list screen on the display means 105, the process-machine assignment means 153 and the process-worker assignment means 154 The warning part on the process plan table screen is displayed by the display means 105 (FIG. 17). For example, when the machine name is clicked with the input means 104, the above-described machine plan chart 12 is opened (displayed), and when the operator name is clicked with the input means 104, the worker plan chart 14 is opened.

  5 Order and arrange parts necessary for manufacturing lots.

  (1) Ordering parts necessary for each lot individually for each lot.

  From the item information display field 46 of the manufacturing plan chart 11 displayed on the display means 105, a lot to be ordered is selected by the input means 104, and when the “print order print” menu is clicked, the production management program 1 causes the member ordering means 155. Is activated (FIG. 18). In this case, the member ordering means 155 displays the ordering order screen 21 by the display means 105, and the lot product selected by the input means 104 from the product process master registered in advance in the product process master storage unit 122 of the external database 4. The bill of materials for the lot product is read out, and the order sheet 30 for the member necessary for the lot product is output (issued) to a printing apparatus (not shown) such as a printer. Note that the order form 30 may be configured to directly transmit data to the member supplier terminal via the network.

  (2) Look at the inventory list and the loading / unloading schedule and place an order for commonly used parts.

  When a specific lot is selected by the input means 104 from the item information display field 46 of the manufacturing plan chart 11 displayed on the display means 105 and the “inventory inquiry” menu is clicked, the production management program 1 activates the member ordering means 155. (FIG. 19).

  In this case, the member ordering means 155 displays the inventory list 16 in which the inventory list of the necessary members and the entry / exit schedule are described by the display means 105, and the inventory list 16 can be used to identify the inventory crack (FIG. 20). . The inventory list 16 is composed of a table in which a plurality of inventory product lines each composed of an item information display column 66 arranged on the left side and an inventory status display column 67 arranged on the right side are arranged vertically. The inventory line reads out the parts table for the lot product selected by the input means 104 and the members necessary for manufacturing the product from the product process master registered in advance in the product process master storage unit 122 of the external database 4. Automatically provided. In the item information display column 66, information corresponding to the schedule displayed in the inventory status display column 67 is displayed, and in this case, inventory information regarding the product or member to be in stock is displayed. In the inventory status display column 67, a plurality of cells are arranged in two rows every day, the number of stocks of the product or member is displayed in the first cell, and the number of cracked stocks in the second cell. (Insufficient number) is displayed.

  The number of stocks displayed in the stock status display column 67 is automatically calculated based on the production plan drafted in the manufacturing plan chart 11, that is, the receipt or delivery of products or parts included in the lot information stored in the lot information storage unit 121. Is done. That is, for products, the day corresponding to the end position of the gantt bar indicating the final process of the process gantt bar 44 corresponds to the entry date, and for members, the day corresponding to the start point position of each gantt bar constituting the process gantt bar 44 is the delivery date. Equivalent to. Then, the member ordering means 155 adds the number of product lots from the number of cells in stock corresponding to the date of goods receipt, and the number of products in the cell from the number of cells corresponding to the date of goods delivery per product. The number of stocks for each day is calculated by subtracting the number multiplied by the number of members used.

  By performing operation input with the input means 104 while displaying the inventory list 16 on the display means 105, the member ordering means 155 provides an order form 30 for purchasing before the parts are out of stock, such as a printer (not shown). Issued on the printing device. As a result, since only the members necessary for the production of the ordered product are ordered, inventory risk can be reduced. Note that the member ordering means 155 may be configured so that the order form 30 is directly transmitted to the member supplier terminal via the network.

  6 Issue work instructions for lots.

  From the item information display field 46 of the manufacturing plan chart 11 displayed on the display means 105, a lot to be instructed for work is selected by the input means 104, and when the "work instruction document printing" menu is clicked, the production management program 1 is operated. The information management means 156 is activated (FIG. 21).

  In this case, the work information management means 156 issues a work instruction 31 for manufacturing the selected lot product with a printing device such as a printer (FIG. 22). In the work instruction sheet 31, for example, lot information such as the product name, delivery date, quantity, manufacturing process name, and scheduled work date read by the work information management unit 156 from the lot information storage unit 121 is appropriately described. In the work instruction sheet 31 shown, it is noted that a barcode 68 as a code that can be read by the result input terminal 32 provided at the production site is printed corresponding to each manufacturing process.

  7 Collect lot work results.

  The work instruction sheet 31 is input to the production site and is a work record collection screen 23 (FIG. 23) which becomes a bar code work progress input screen. For example, the work start / completion, the machine and worker who worked, the number of finished good products and defects Enter the number and cause of failure. The work result collection screen 23 is displayed on the display means of the terminal device (not shown) arranged at the production site by the work information management means 156. Regarding the start and completion of work, the work instruction sheet 31 is displayed. By reading the barcode 68 printed on the record with the record input terminal 32, that is, a barcode reader as an optical reading means, the work record can be easily input. The work information management means 156 automatically acquires the current time at the time of the input as the work start time or work completion time. In this embodiment, results are input using a bar code, but input from a touch panel provided in the terminal device is also possible as an option.

  8 Work results are displayed on the Gantt chart.

  In response to the work results input from the terminal device at the production site, the work information management means 156 includes a manufacturing plan chart 11 for each lot product, a machine plan chart 12 for each machine facility, and a worker plan chart 14 for each worker. The work results are displayed as needed (FIG. 24). At this time, in the production plan chart 11, in the Gantt chart display field 43 relating to the same lot product, the process Gantt bar 44 showing the process plan is displayed above, and the result bar 70 is displayed below. In the machine plan chart 12 and the worker plan chart 14, only the performance bar 70 is displayed in the Gantt chart display fields 47 and 52. The work information management means 156 records the work results collected in this way as a work result history in the sequential production processing information storage unit 123. By analyzing the history of work results forming part of the production information, for example, the work time registered in advance in the product process master of the external database 4 is updated, or the worker's standard work time is calculated and the worker is calculated. You can also evaluate your skills.

  Next, another functional configuration of the control means 101 will be described with reference to FIGS. FIG. 25 shows the procedure of the process plan simulation function by the process-machine allocation means 153. First, a lot product to be simulated is specified by clicking operation using the input means 104, and the start date of the product is input. As an example, here, in the state where the manufacturing plan chart 11 is displayed on the display means 105, the item information display column 42 of the product name “MS-100” is clicked, and the start date and time is set to “July 6 8: In this case, “00” is entered (see the upper left column in FIG. 25).

  Upon receiving such input, the process-machine allocation means 153 extracts each information of the manufacturing process of the specified lot product and the required time associated with it from the product process master stored in the product process master storage unit 122. To do. Next, usable machine equipment that can be processed for each extracted manufacturing process is searched from the machine equipment information stored in the machine equipment information storage unit 124. As an example, the product name “MS-100” is manufactured in the order of “cutting” → “blank” → “bending” → “welding” by the product process master stored in the product process master storage unit 122. It is. When the process-machine allocation means 153 extracts this information, the machine equipment that can start and finish the work in the shortest time for each manufacturing process is selected from the machine equipment information stored in the machine equipment information storage unit 124. Find out. Here, the work time of each machine facility is determined by the process-machine allocation means based on the required time of the manufacturing process stored in the product process master storage unit 122 and the capability of the machine facility stored in the machine facility information storage unit 124. 153 is calculated. In other words, even if a machine is capable of starting work earlier, if the capacity is lower than that of another machine and the work end time is delayed, another machine with an earlier work end time is preferentially selected. The

  In the example of FIG. 25, regarding the manufacturing process of “cutting”, the mechanical equipment “Shirling No. 1” that completes the work in the shortest time is selected (working time is 8: 00 to 8: 40), followed by “blank”. In relation to the manufacturing process, a machine facility called “Tarepan No. 1” is selected which finishes the work in the shortest time. Here, regarding the manufacturing process of the next “bending”, it is assumed that three machine facilities capable of performing the manufacturing process are extracted from the machine facility information storage unit 124. When the operating status included in the machine equipment information is displayed on the machine plan chart 12 for each of these machine equipments, both “Vendor No. 1” and “Vendor No. 2” are free from 9:45 to 12:00. “Vendor 3” has an empty time from 9:45 to 11:00 (see the lower right column in FIG. 25). The process-machine allocation means 153 selects “Vendor No. 1” having the highest capability from these idle times and the capabilities of each mechanical facility included in the mechanical facility information, and calculates the work start and end times. .

  As shown in the upper right column of FIG. 25, if the manufacturing process of “bending” is performed by “Bender No. 1”, the operation starts at 10:00 and ends at 10:50. Calculated by the machine allocation means 153. The process-machine allocating means 153 selects the machine equipment “YAG Laser No. 1” that completes the work in the shortest time for the next “welding” manufacturing process. Thus, when the operation start date and time is input from the input means 104 in relation to a specific lot product, the process-machine allocation means 153, in accordance with the lot information of the product and the machine equipment information, in the order of each manufacturing process related to the product. Extract machinery and equipment that can be used in the shortest working time.

  Next, the process-machine allocation unit 153 causes the display unit 105 to display a process plan graph 201 that is accumulated in time series in the order of the manufacturing process for each extracted machine facility. In the process plan graph 201, elements 202a to 202d describing manufacturing process names and machine facilities to be used are displayed along a time axis display unit 206 indicating required time. On one side of each of the elements 202a to 202d, the start time and end time in each manufacturing process are displayed as a time display unit 207, and as shown in the process plan graph 201 on the left side, It is possible to recognize at a glance the required equipment for each manufacturing process and all manufacturing processes, and the machine equipment or workers that can be used in the shortest working time.

  Further, another machine facility can be selected by the input means 104 from the state where the process plan graph 201 is shown. For example, when the process plan graph 201 on the left side is displayed, when the user clicks on the element 202c for which “Vendor No. 1” has been selected by the input means 104, an instruction is given to select another “Vendor No. 2” mechanical equipment. The process-machine allocation means 153 calculates the work start time and end time for “Bender 2” and develops them in the process plan graph 201. The central process plan graph 201 shows the display result. Since “Vendor No. 2” has lower capability than “Vendor No. 1”, it can be understood from the display of the element 202c that the work end time is extended to 11:40. As a result, it is possible to recognize at a glance a bottleneck that requires time for the work plan of the product name “MS-100”.

  Further, here, from the state in which the process plan graph 201 is shown, a plurality of mechanical facilities can be selected for one manufacturing process by the input means 104. Specifically, in the state where the central process plan graph 201 is displayed, the user clicks on the element 202c in which “vendor 2” is selected by the input means 104, for example, the machines of “vendor 2” and “vendor 3”. When instructed to select the equipment, the process-machine allocation means 153 performs the work start time and end time of “vendor 2” and “vendor 3” that can be processed in the shortest time by two machine equipments. Is calculated and developed in the process plan graph 201. Here, it can be understood from the display of the element 202c that the work end time is shortened to 10:20 by simultaneously operating two units of “vendor 2” and “vendor 3”. In this way, the process-machine allocation means 153 automatically displays the horizontal development in consideration of the operation of a plurality of machine facilities to be used on the process plan graph 201, thereby eliminating the bottleneck and changing the manufacturing time for the user. Can be clearly understood.

  The process plan graph 201 showing the simulation result regarding the process plan of the lot can be reflected on the process gantt bar 44 on the manufacturing plan chart 11 by operating the specific input means 104. When this operation is performed, the Gantt chart generation unit 152 sets the length of the process Gantt bar 44 based on the start time and end time of each manufacturing process specified by the process-machine allocation unit 153, and this is set in the Gantt chart. It is displayed on the display column 43. In the lower left column of FIG. 25, the process gantt bars 44a to 44d developed on the manufacturing plan chart 11 based on the process plan graph 201 shown on the right side of the upper right column of FIG. Here, since bending is performed by two machine facilities, the process gantt bar 44c corresponding to the bending manufacturing process is displayed in two upper and lower stages. Thereby, the user can understand immediately that it is a manufacturing process by a some mechanical installation. Conversely, when the specific input means 104 is operated from the state where the respective process Gantt bars 44a to 44d are displayed in the Gantt chart display field 43, the above-described process plan graph 201 can be displayed.

  In addition, in the case where the mechanical equipment capable of performing a specific manufacturing process does not have sufficient free time to perform work at the same time in the series of steps described above, the empty time and the next free time for the manufacturing process. The input means 104 may select whether to divide the work time into two hours or to concentrate the work time on the next idle time at which work can be performed at once. FIG. 25 describes the mechanical equipment, but if the process-worker assigning means 154 has the same function, an optimal plan simulation can be performed for the work. In this case, what is necessary is just to replace a mechanical installation with an operator by the above-mentioned description.

  26 and 27 show specific examples of the cross scale display function by the process-machine allocating unit 153 and the process-worker allocating unit 154. FIG. First, from the example of FIG. 26, here, the window displayed on the display means 105 is divided into two parts, and a manufacturing plan chart 11 which is displayed as a “lot-by-lot Gantt chart” is displayed above, and below the “by machine” A machine plan chart 12 that is displayed as “Gantt chart” is displayed. In addition, the manufacturing plan chart 11 and the machine plan chart 12 displayed side by side on the common time axis 220 can be linked to the direction of the time axis 220 by operating the input means 104. By operating the means 104, it is possible to scroll simultaneously in the upper and lower windows while keeping the time axis 220 shared regardless of which of the Gantt chart display fields 43 and 47 is horizontally scrolled.

  In this example, when a specific click operation is performed by the input means 104, the process-machine allocation is performed so that the position where the pointer 210 is displayed is the intersection 211a in the state where the manufacturing plan chart 11 and the machine plan chart 12 are displayed at the same time. Means 153 is to display the cross scale 211. The cross scale 211 is parallel to the time axis 210 and extends along the Gantt chart display fields 43 and 47 corresponding to one lot or machine facility, and is perpendicular to the time axis 220 and is connected to the lot and machine facility. It consists of a vertical line 211c extending across the Gantt chart display fields 43 and 47, and the intersection 211a can be moved to an arbitrary position by operating the input means 104. Incidentally, in FIG. 26, the horizontal line 211b is displayed along the Gantt chart display field 43 of a specific lot product, but by moving the intersection 211a, along the Gantt chart display field 47 of a specific machine facility, The horizontal line 211b can also be displayed.

  In this way, it becomes clear which lot or machine equipment Gantt chart display fields 43 and 47 are shown by the horizontal line 211b of the cross scale 211, and the vertical line 211c of the cross scale 211 and the production plan chart 11 The time on the machine plan chart 12 is clearly understood. In addition, since this vertical line 211c is displayed by penetrating from the production plan chart 11 to the machine plan chart 12, even if a plurality of process Gantt bars 44 are scattered on the production plan chart 11 and the machine plan chart 12, any lot You can clearly understand which machine equipment corresponds to the manufacturing process.

  The cross scale 211 can also be applied to the case where the production plan chart 11 and the worker plan chart 14 are arranged in parallel vertically and displayed on the display means 105 with the common time axis 220 as the horizontal axis. FIG. 27 shows an example. The intersection 211a can be moved to an arbitrary position by the operation of the input means 104. The horizontal line 211b of the cross scale 211 indicates which lot or worker's Gantt chart display fields 43, 47. The time on the manufacturing plan chart 11 and the worker plan chart 14 can be clearly understood by the vertical line 211c of the cross scale 211. Further, since this vertical line 211c is displayed through the production plan chart 11 to the worker plan chart 14, even if a plurality of process gantt bars 44 are scattered on the production plan chart 11 and the worker plan chart 14, You can clearly understand which worker corresponds to which lot's manufacturing process.

  The cross scale 211 can be switched between display and non-display by operating the input means 104. In this way, the cross scale 211 can be displayed only when necessary.

  Next, with respect to one manufacturing process, a function of lateral development that enables a plurality of loads such as mechanical equipment and workers to be used will be described with reference to FIGS. 28 to 30. Such a function is realized by the process-machine assignment means 153 and the process-worker assignment means 154.

  The specific procedure will be described. In FIG. 28, the window displayed on the display means 105 is divided into two parts, and a production plan chart 11 that is displayed as a “lot-by-lot Gantt chart” is displayed above. A machine plan chart 12 which is a “chart” display is displayed. A process gantt bar 44 corresponding to the manufacturing process of each lot product is displayed on both the manufacturing plan chart 11 and the machine plan chart 12. In other words, here, the allocation of the manufacturing process and the mechanical equipment is completed, and it is determined which mechanical equipment is used for each manufacturing process of the lot.

  Here, by operating the input means 104, a cursor (pointer) is moved onto the process gantry bar 44a corresponding to one manufacturing process "welding", and when a specific operation (right mouse click) is performed there, process-machine allocation The means 153 is activated, and a menu selection screen 231 as shown in FIG. Then, when the display unit 231a corresponding to “process horizontal development screen display” is clicked on the menu selection screen 231 by the input means 104, the process-machine allocation means 153 displays the horizontal development display as shown in FIG. A screen 233 is displayed on the display means 105.

  The horizontal development display screen 233 displays various items included in the process Gantt bar 44a, such as customer name, figure number / part number, version number, product name, (manufacturing) process name, number of manufactures, and number of instructions. A lot / process display unit 235 and a horizontal development destination display unit 236 that displays items such as the name of the machine to be used, the number of instructions, and the name of the subcontractor are displayed. Each item of the lot / process display unit 235 is displayed by reading the lot information related to the lot product of the process Gantt bar 44a from the lot information storage unit 121. From the horizontal development display screen 233, each item is input. I can't do it. On the other hand, the lateral development destination display unit 236 corresponds to a condition input unit that instructs how many production numbers (instruction numbers) are to be assigned to which mechanical equipment regarding the manufacturing process corresponding to the process Gantt bar 44a. Here, two or more mechanical facilities can be designated. The number of instructions is specified so that the total number finally matches the number of manufactures. If the total number of instructions does not match the number of manufactures, an alarm may be displayed to prompt re-input.

  As an example, here, by inputting from the input means 104, 400 instruction numbers are specified for the machine equipment “Laser Welder 2”, and 400 instructions number is specified for another “Laser Welder 1” machine equipment. specify. When the total number of instructions for each machine facility matches the number of manufactured items, when the registration button 237 is clicked, the process-machine allocation means 153 displays the capacity and operating status (operating rate) for each machine facility. It reads out from the machine equipment information stored in the equipment information storage unit 124, and searches for a time zone during which work can be performed for the number of instructions input as a condition.

  Here, not only the number of instructions but also a period for which the manufacturing process is to be performed, that is, a work period (for example, March 15 to March 20 in FIG. 29) may be input as a condition. Further, it is possible to use only the work period as a condition without inputting the number of instructions. In any case, when a plurality of machine facilities to be used and the number and / or period to be manufactured in each machine facility are input as conditions, the process-machine allocation means 153 determines whether or not these conditions are met. If the conditions are met, the laterally expanded process Gantt bars 244a and 244b specifying the work start and end times of each mechanical facility are displayed at corresponding locations in the manufacturing plan chart 11 and the machine plan chart 12.

  FIG. 30 shows the display result. Before the lateral development shown in FIG. 28, the mechanical equipment of a single “laser welding machine 1” was used from 8:30 to 17:30 on March 20. The production process of “welding” is planned to be performed with the production number of 800 pieces, but after the lateral development shown in FIG. 30, at 10:15 to 17:00 on March 19 earlier than that, Using the machine equipment of “Laser Welding Machine 1”, the “welding” production process is performed with the number of manufactured 400 pieces, and another “Laser Welding Machine 2” machine is run from 11:30 to 18:15 on the same day Using the equipment, it is possible to make a plan to simultaneously perform the “welding” manufacturing process with the number of 400 manufactured. After horizontal development, since multiple process Gantt bars 244a and 244b are displayed side by side in the Gantt chart display field 43 of the same lot product, the Gantt chart display field 43 of the lot product automatically sets the vertical width. It is preferable to spread it.

  Returning to FIG. 28 again, another horizontal development procedure will be described. In the menu selection screen 231 displayed in this figure, when the display unit 231b corresponding to “horizontal development of process” is click-operated by the input means 104, the process-machine allocation means 153 causes only the designated process Gantt bar 44a. Allows the drag and drop operation to be performed by the input means 104, while the other process Gantt bar 44 is processed on software so that the drag and drop operation cannot be performed. In this case, the process gantt bar 44a that can be operated may be clarified by changing the designated process gantt bar 44a to another display form (for example, a thick red dotted line frame).

  When the process Gantt bar 44a is dragged and dropped to the machine plan chart 12, the process-machine allocation means 153 displays an instruction number input screen 261 for prompting the input of the production number (instruction number) for the operation destination machine equipment. Display on means 105. FIG. 31 shows an example of the instruction number input screen 261. Here, in addition to the customer name, process name, and part name, a box 261a for inputting the instruction number is included.

  Next, when the number of instructions is input to the box 261a by the input means 104 and the registration button 237 is clicked, the process-machine allocation means 153 stores the capacity and operating status (operating rate) of the mechanical equipment in the mechanical equipment information storage. The machine equipment information stored in the unit 124 is read out, and a time zone in which the work can be performed with respect to the number of instructions input as a condition is found. In this case as well, the number and / or period to be manufactured in each machine facility may be input as a condition. The process-machine allocating means 153 determines whether or not these conditions are met. If the conditions are met, the process development machine Gantt bar 244a that specifies the work start time and end time for the machine equipment is displayed in the manufacturing plan chart 11 and It is displayed in the corresponding part of the machine plan chart 12. FIG. 32 shows an example of the display. As for the process Gantt bar 244a, it is assumed that mechanical equipment has been determined, and the display form is switched from a red thick dotted line frame to another red solid line frame, for example. In addition, for the remaining number of instructions obtained by subtracting the number of instructions designated in the box 261a from the number of products manufactured, the process gantt bar 244b with a red bold dotted line frame indicating that the mechanical equipment has not been determined is a production plan chart. 11 is displayed in two. Also for the process Gantt bar 244b, the machinery and equipment to be used can be determined by the drag-and-drop operation described above and the input of the number of instructions, and finally the display state as shown in FIG. 30 can be obtained. .

  In this case, input of mechanical equipment to be used can be performed by a drag-and-drop operation, and operability can be improved. It should be noted that the process-machine allocation means 153 may be configured not to accept such input or operation when a machine facility that does not correspond to the manufacturing process is input or dragged and dropped.

  In this way, when a plurality of machine facilities are laterally expanded for one manufacturing process, the operation rates of the replicated process Gantt bars 244a and 244b are calculated for these machine facilities and include the operation rates. The machine equipment information is used together with the machine equipment information storage unit 124 in the production process of the product related to the process gantt bar 44a. Rewritten and updated in the storage unit 123.

  In the description of the lateral development related to FIGS. 28 to 32, other combinations of one manufacturing process and a plurality of workers may be considered in the same manner. That is, the process-worker allocating unit 154 may have the same function, and in that case, the mechanical equipment may be replaced with the worker in the above description.

  In addition, the functional configuration related to the above embodiment will be described. FIG. 33 shows a display example when manufacturing processes of a plurality of lot products overlap in the same time zone of the same mechanical equipment. In such a case, the process-machine allocation means 153 includes the process Gantt bars 344a to 344d in the Gantt chart display field 43 of the manufacturing plan chart 11 and the Gantt chart display field 47 of the machine plan chart 12 reproduced correspondingly. In the vicinity of the process gantt bars 344a to 344d, for example, a display unit 345 "Machine connection" is provided to clarify that fact. Further, in this figure, the delivery date for each lot product is displayed on the delivery date display unit 346. The delivery date display unit 346 is provided at a position corresponding to the time axis 220, so that it is possible to intuitively know what time is the delivery date for each lot. In addition, if the process gantt bar 354a exists after the delivery date, a display unit 355 “delayed delivery date” is provided in the vicinity of the process gantt bar 354a, so that the current plan does not make it in time for delivery. I can inform you.

  FIG. 34 shows an example in which connections between the gantt bars constituting the process gantt bar 44 are displayed by connection lines. When the cursor (pointer) is moved to one lot displayed in the item information display field 42 by the operation of the input means 104 and a specific operation is performed there, the process-machine allocation means 153 is designated by the input means 104. It is extracted from the production processing information stored in the production information storage unit 123 what kind of manufacturing process the obtained lot includes. Then, a series of manufacturing processes are specified for the lot, and a link bar 450 is displayed between the process Gantt bars 444a to 444e on the machine plan chart 12 corresponding to the manufacturing process. By doing so, it is possible to understand what kind of mechanical equipment is used for the lot, and it is possible to understand where the work in progress is located.

  In addition, instead of moving the cursor (pointer) onto one lot displayed in the item information display field 42 by the operation of the input means 104, the cursor is placed on, for example, one process Gantt bar 444c where the link bar 450 is to be displayed. The (pointer) may be moved and a specific operation may be performed there. The process-machine allocation unit 153 extracts from the production processing information stored in the production information storage unit 123 what manufacturing process the lot associated with the process Gantt bar 444c specified by the input unit 104 includes. Then, a series of manufacturing processes are specified for the lot, and a link bar 450 is displayed between the process Gantt bars 444a to 444e on the machine plan chart 12 corresponding to the manufacturing process.
