Description

  The present invention relates to an inventory management apparatus that orders products and parts and replenishes inventory.

  In the retail and manufacturing industries, when replenishing inventory of products and parts, the user enters data into an input area such as a text box displayed on the screen of the inventory management device, and selects or selects the quantity of products or parts. Or stock replenishment has been performed. In inventory replenishment, parameters that are factors that determine the inventory replenishment policy include order points and replenishment points.

  In many cases, the ordering points and the supplementary points are determined for each product or part, or for each product (part) category that is a group of products or parts classified by a predetermined rule according to function or application. And stock replenishment of products, parts, etc. is performed according to such parameters. The parameters are stored in the database and are reviewed regularly. At this time, this database is edited by the inventory management apparatus.

The user of the inventory management apparatus sets individual parameters by inputting a value into a text box on the parameter editing screen displayed on the inventory management apparatus.
These individual parameters are related, and the value of one parameter may be constrained by the value of another parameter. For example, there is a restriction that replenishment points and order points are related, and replenishment points cannot fall below order points. In addition, the replenishment point is meaningful only when the ordering method is the replenishment point ordering method, and need not be set for other ordering methods.

Moreover, about a specific parameter, the value derived | led-out by the predetermined | prescribed calculation formula may be set based on another parameter and the past track record. For example, the safety stock can be obtained from three parameters: an allowable shortage rate, a demand standard deviation, and a lead time. Of these, the demand standard deviation can be obtained from past sales results.
When setting the safety stock, there are users who set the safety stock (theoretical safety stock) obtained by such calculation, and there are users who set the safety stock based on an original concept.

In this way, the individual parameters are related, and in a general inventory management apparatus, an error occurs when a value that causes a contradictory relationship between parameters is input.
As a technique for notifying that an input value is an error, for example, a technique called “validation” is known in a Web browser. This technology verifies whether or not the value entered in the input area such as an input form conforms to a predetermined rule, and displays an error if the result does not conform. Thus, the user is notified that the input value is incorrect.

  Further, the technique described in Patent Document 1 displays a code such as “x” in the title portion of a tab when data input to a text box in a certain tab is incorrect. When the user moves the mouse pointer over the code, a rectangle (tooltip) indicating information about the error is displayed near the code.

JP 2006-178971 A (paragraph 0015)

  However, in the technique described in Patent Literature 1, even if notified that the input data is incorrect, a user who is not familiar with a predetermined rule can modify the data. I do n’t know if it ’s good.

  Similarly, when a user who is not familiar with inventory management performs inventory replenishment, it is difficult to set a value while considering the relationship between parameters. In the conventional inventory management device, an error occurs at the end of input for an incorrect input value, but the following error will occur even if the user inputs a corrected value. May be repeated. As a result, it takes a long time to input values that do not contradict the relationship between parameters.

  Further, when a value obtained by calculation (for example, theoretical safety stock) is set as a parameter, the user may obtain the value of the target parameter every time the inventory is replenished. As for the parameter, for example, the value of the target parameter can be obtained based on past results or other parameters using spreadsheet software or the like. Then, the user inputs the obtained value into the input area of the inventory management apparatus. In this way, using spreadsheet software, it is possible to set a value derived by a predetermined calculation formula at a time for a plurality of products, etc., but the value does not necessarily suit all products. . For example, when the lead time of a product, etc. is obtained based on the interval between the past ordering record and its production record, the average value of the interval is optimal for a certain product, etc. The value may be optimal.

  Thus, in inventory replenishment, when inputting parameter values, the relationship between the parameters can be grasped in advance, and if the input value is incorrect, the value is automatically corrected, There is a need for an inventory management device that can be selected from candidates automatically calculated.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an inventory management apparatus in which necessary information can be easily set in inventory replenishment.

  In order to solve the above problem, an inventory management apparatus according to a first aspect of the invention is an inventory management apparatus that performs inventory management in accordance with parameters that are elements that determine a policy for restocking products and parts, and stores the inventory management apparatus. The unit stores parameter related information storing associations with other parameters in association with an ordering method, which is a fixed method when stock replenishment, and the parameters, and the inventory management device The control unit acquires the ordering method selected by the user on the parameter editing screen, which is a screen for selecting and specifying the ordering method and the parameter displayed on the output unit, and stores the ordering method in association with the acquired ordering method. An association between the parameter being set and the other parameter is obtained from the parameter related information, and Displaying a graphic associated area to specify the other parameters to one another on the parameter editing screen, characterized in that.

  Further, the storage unit of the inventory management apparatus of the second invention further stores unused parameter information storing the parameters not used in the ordering method in association with the ordering method. The control unit of the management apparatus acquires parameters stored in association with the acquired ordering method from the unused parameter information, and inactivates or inactivates an area for specifying the acquired parameters on the parameter editing screen. It is characterized by display.

In the third aspect of the present invention, the parameter-related information further stores a correction formula that is a formula for correcting the value of the parameter. The parameter value selected by the user is corrected based on the correction formula and displayed.
Other inventions will be clarified in this specification.

<Operation screen (during parameter input)>
Next, the parameter editing screen 200 during parameter input will be described with reference to FIG. (A) is a figure explaining the parameter edit screen 200 during parameter input when the ordering method is “order point ordering”. (B) is a diagram illustrating the parameter editing screen 200 during parameter input when the ordering method is “replenishment point ordering”.

As shown in FIG. 10A, when “ordering point ordering” is selected in the ordering method column 201, the replenishment point column 205 is inactivated or hidden, and the related line 221a is displayed.
The reason why the replenishment point column 205 becomes inactive is that, in the unused parameter information 131 (see FIG. 3), when the ordering method is “order point ordering”, information that the parameter “replenishment point” is not used. Because it is remembered. If a value has already been entered in the replenishment point column 205, that value is also inactivated or hidden.
Further, the relation line 221a, which is an arrow having the lot size column 202 as the starting point and the order quantity column 203 as the end point, is displayed when the ordering method is “order point ordering” in the parameter related information 132 (see FIG. 4). This is because, in some cases, information that the parameter “order quantity” is constrained by the parameter “lot size” is stored.

As shown in FIG. 10B, when “replenishment point ordering” is selected in the ordering method column 201, the order amount column 203 becomes inactive or hidden, and a related line 221b is displayed.
The order quantity column 203 becomes inactive, for example, in the non-use parameter information 131 (see FIG. 3), when the ordering method is “replenishment point order”, information that the parameter “order quantity” is not used. Because it is remembered. If a value has already been entered in the order quantity column 203, that value is also inactive or hidden.
In addition, the relation line 221b, which is a bidirectional arrow with the order point column 204 and the replenishment point column 205 at both ends, is displayed when the ordering method is “replenishment point order” in the parameter related information 132 (see FIG. 4). This is because, in some cases, information that the parameters “order point” and “replenishment point” are mutually constrained is stored.

<Operation screen (modification of parameter values)>
Next, the parameter editing screen 200 when the input parameter value is modified will be described with reference to FIG. (A) is a figure explaining the parameter edit screen 200 before the value of a parameter is corrected. (B) is a figure explaining the parameter edit screen 200 after the value of a parameter is corrected.

As shown in FIG. 11A, “ordering point ordering” is selected in the ordering method column 201, and “10” is input in the lot size column 202. In the parameter related information 132 (see FIG. 4), it is stored that the parameter “order quantity” must be a multiple of the parameter “lot size” when the ordering method is “order point order”.
In this case, when the user inputs “98” in the order quantity field 203 and presses the enter key of the keyboard to confirm the input value or move the cursor to another input area, FIG. As shown in (b), “98” input in the order quantity field 203 is automatically corrected to “100”. In addition, a tool tip 222 indicating a message “Matched to lot size” is displayed near the order quantity column 203. The tool tip 222 indicates information notified to the user by the inventory management apparatus 100. In the present embodiment, the tooltip 222 indicates information in the vicinity of a location where an error has occurred or a location where a value is automatically corrected. It is assumed that a rectangle is displayed as the tool tip 222.

<Operation screen (parameter value candidate display)>
Next, the parameter editing screen 200 when parameter value candidates are displayed will be described with reference to FIG. (A) is a figure explaining the parameter edit screen 200 in case the parameter value candidate is displayed. (B) is a figure explaining the parameter edit screen 200 from which the parameter value candidate was selected.

  As shown in FIG. 12A, when the user moves the mouse pointer 223 on the order point column 204 and right-clicks, a context menu 224 is displayed near the mouse pointer. The context menu 224 shows parameter value candidates (parameter candidates and values) automatically calculated by the inventory management apparatus 100. In FIG. 12A, right-clicking has been performed on the order point column 204, so order point value candidates are displayed in the context menu 224.

  The parameter value candidates displayed on the context menu 224 are calculated based on the parameter selection candidate information 133 (see FIG. 5). In FIG. 5, the parameter “order point” value candidates include “theoretical order point”, “actual maximum order point”, “actual minimum order point”, “actual average order point” as shown in the parameter candidate column 1332. There are five items, “the latest order points for achievements”. These candidates are calculated by a method as shown in the calculation method column 1333.

  When the user selects one of the parameter value candidates displayed on the context menu 224 by operating the mouse or the like, the selected parameter value is input to the input area as shown in FIG. And the context menu 224 is hidden. In FIG. 12B, since the value “98”, which is the parameter candidate “actual minimum order point” shown in FIG. 12A, is selected, “98” is set in the order point column 204. The

<Processing content>
Next, processing contents of the inventory management apparatus 100 will be described with reference to FIG. FIG. 13 is a flowchart of processing performed by the inventory management apparatus 100.

  In step S1301, the control unit of the inventory management apparatus 100 detects that the input device 140 has been operated by the user. Then, the process proceeds to step S1302.

In step S1302, the control unit of the inventory management apparatus 100 determines what the operation detected in step S1301 is.
If the operation is “select ordering method”, the process advances to step S1311. Here, the selection of the ordering method means that the ordering method is input or selected in the ordering method column 201 on the parameter editing screen 200 (see FIG. 2).
If the operation is “input value”, the process proceeds to step S1321. Here, the value input means that a value has been input to the lot size column 202 to the order cycle column 210 on the parameter editing screen 200 (see FIG. 2).
If the operation is “right click”, the process advances to step S1331. Here, right-clicking means that the user has right-clicked on the parameter editing screen 200 by operating the mouse.

  In step S1311, the rule check unit 121 acquires the ordering method input or selected in the ordering method column 201 on the parameter editing screen 200 (see FIG. 2). Then, the process proceeds to step S1312.

  In step S1312, the rule check unit 121 acquires unused parameter information 131 (see FIG. 3). Specifically, the rule check unit 121 acquires from the unused parameter information 131 a parameter (unused parameter) stored in association with the ordering method acquired in step S1311. Then, the process proceeds to step S1313.

In step S1313, the rule check unit 121 determines whether there is an unused parameter. Specifically, the rule check unit 121 determines whether or not the unused parameter has been acquired in step S1312.
If there are unused parameters (can be acquired) (step S1313 “Yes”), the process proceeds to step S1314.
If there is no unused parameter (cannot be acquired) (step S1313 “No”), the process proceeds to step S1315.

  In step S <b> 1314, the rule check unit 121 displays the unused parameter input area in an inactive display. Specifically, the rule check unit 121 sets the area to which the parameter (unused parameter) acquired in step S1312 is input as inactive or hidden as shown in FIG. Then, the process proceeds to step S1315.

  In step S1315, the rule check unit 121 acquires the parameter related information 132 (see FIG. 4). Specifically, the rule check unit 121 acquires, from the parameter related information 132, parameters and related information stored in association with the ordering method acquired in step S1311. Then, the process proceeds to step S1316.

In step S1316, the rule check unit 121 determines whether there is a relationship between parameters. Specifically, the rule check unit 121 determines whether parameters and related information have been acquired in step S1315.
If there is a relationship (parameters and related information can be acquired) (step S1316 “Yes”), the process proceeds to step S1317.
If there is no relationship (parameter and related information could not be acquired) (step S1316 “No”), the process returns to step S1301.

  In step S1317, the rule check unit 121 displays a related line. Specifically, the rule check unit 121 displays a related line as shown in FIG. 10 based on the parameter and related information acquired in step S1315. Then, the process returns to step S1301.

  In step S1321, the data correction unit 122 acquires the ordering method and the input area input or selected in the ordering method column 201 on the parameter editing screen 200 (see FIG. 2). Here, acquiring the input area means determining which one of the lot size column 202 to the ordering cycle column 210 (which parameter value has been input) is the region where the user has input a value. Say. Then, the process proceeds to step S1322.

  In step S1322, the data correction unit 122 acquires the parameter related information 132 (see FIG. 4). Specifically, the data correction unit 122 acquires, from the parameter related information 132, related information and a correction formula stored in association with the ordering method and the input area (that is, parameters) acquired in step S1321. Then, the process proceeds to step S1323.

In step S1323, the data correction unit 122 determines whether there is corresponding information. Specifically, the rule check unit 121 determines whether or not related information and a correction formula have been acquired in step S1322.
When there is information (relevant information and a correction formula have been acquired) (step S1323 “Yes”), the process proceeds to step S1324.
When there is no information (related information and correction formula could not be acquired) (step S1323 “No”), the process returns to step S1301.

In step S1324, the data correction unit 122 confirms the appropriateness of the input value. Specifically, the data correction unit 122 determines whether or not the value input by the user is appropriate based on the related information and the correction formula acquired in step S1322. Here, the value being appropriate means that the value is in accordance with the related information acquired in step S1322.
If the input value is appropriate (step S1324 “Yes”), the process returns to step S1301.
If the input value is not appropriate (step S1324 “No”), the process proceeds to step S1325.

  In step S1325, the data correction unit 122 corrects the value and displays a tool tip. Specifically, the data correction unit 122 corrects the value input by the user based on the correction formula acquired in step S1322, and displays the tool tip 222 as shown in FIG. Then, the process returns to step S1301.

  In step S1331, the context menu control unit 124 acquires the click position. Here, the click position is the position where the user right-clicked (that is, the parameter that was right-clicked) in any of the order method column 201 to the order cycle column 210 of the parameter editing screen 200 (see FIG. 2). is there. Then, the process proceeds to step S1332.

  In step S1332, the parameter calculation unit 123 acquires parameter selection candidate information 133 (see FIG. 5). Specifically, the parameter calculation unit 123 acquires parameter candidates and calculation methods stored in association with the parameters acquired in step S1331 from the parameter selection candidate information 133. Then, the process proceeds to step S1333.

In step S1333, the parameter calculation unit 123 determines whether there is corresponding information. Specifically, the parameter calculation unit 123 determines whether or not parameter candidates and calculation methods have been acquired in step S1332.
When there is information (a parameter candidate and a calculation method have been acquired) (step S1333 “Yes”), the process proceeds to step S1334.
When there is no information (a parameter candidate and a calculation method could not be acquired) (step S1333 “No”), the process returns to step S1301.

  In step S1334, the parameter calculation unit 123 and the context menu control unit 124 calculate and display parameter value candidates. Specifically, the parameter calculation unit 123 obtains the parameter candidates and calculation method acquired in step S1332, inventory record information 134 (see FIG. 6), order record information 135 (see FIG. 7), production record information 136 (see FIG. 8). ) And sales performance information 137 (see FIG. 9), parameter value candidates are calculated. Then, the context menu control unit 124 displays the calculated value on the context menu as shown in FIG. 12A and prompts the user to select one. Then, the process proceeds to step S1335.

In step S1335, the context menu control unit 124 detects selection of parameter value candidates. Specifically, the context menu control unit 124 detects which parameter value candidate the user has selected from the context menu displayed in step S1334.
When selection of a candidate is detected (step S1335 “Yes”), the process proceeds to step S1336.
When selection of a candidate is not detected (step S1335 “No”), the process returns to step S1301.

  In step S1336, the context menu control unit 124 sets a value in the input area. Specifically, the context menu control unit 124 sets the selected value detected in step S1335 in the input area corresponding to the click position acquired in step S1331. Then, the process returns to step S1301.

<< Summary >>
The inventory management apparatus 100 of this embodiment can grasp the relationship between parameters in advance, and automatically corrects the value when the input value is invalid, and automatically calculates the parameter value. Since it is possible to select from among the candidates, it is easy to set an appropriate value for the parameter, and it is possible to reduce the burden on the user due to stock replenishment.
Further, as shown in FIG. 11, the inventory management apparatus 100 according to the present embodiment notifies the user of the fact and the details of the correction when the input value is automatically corrected. Even if different values are displayed, you can know why.

<< Other >>
The above-described embodiment is suitable for carrying out the present invention, but the form of implementation is not limited to these, and various modifications can be made without departing from the scope of the present invention. Is possible.

  For example, non-use parameter information 131 (see FIG. 3) to sales performance information 137 (see FIG. 9) is associated with an identifier that uniquely identifies a product or part so that parameters can be set for each product or part. Various types of information are stored. When setting parameters, the user specifies data to be used in various types of information from the unused parameter information 131 (see FIG. 3) to the sales performance information 137 (see FIG. 9) by designating products and parts. Therefore, the processing time of the inventory management apparatus 100 can be shortened.

  In addition, when calculating parameter value candidates in step S1334 of FIG. 13, inventory record information 134 (see FIG. 6), order record information 135 (see FIG. 7), production record information 136 (see FIG. 8), and sales record. Various information of the information 137 (see FIG. 9) is used, but in which range of data is used in the various information may be set in advance or appropriately. The data range may be set based on the date, for example, “target data for the past one year from the date when the inventory management apparatus 100 is operated”.

  Further, the user's error history is stored in association with an identifier that uniquely identifies each user, and information such as what errors have occurred in the past when the user operates the inventory management apparatus 100 May be displayed by a tooltip or the like. Thereby, the user is less likely to cause the same error as in the past, and the work efficiency is improved.

  Further, in FIG. 10, the relation line 221 (221a, 221b), which is a one-way or two-way arrow, is displayed, but the display indicating the relation between parameters is not limited to this. For example, input areas of a plurality of parameters related to each other may be displayed in the same color, surrounded by a frame, or the same symbol such as “★” may be displayed. As a result, symbols, figures, and the like that relate the parameters to each other are displayed, so that the user can easily recognize the relationship between the parameters and easily input values that do not contradict the relationship between the parameters.
