Next, the diagram display processing will be described.

FIG. 10 is a flowchart of the diagram display processing. FIG. 11 is a diagram showing an example of a screen displayed by the diagram display process.

A plurality of node objects 81 and a plurality of flow objects 82 are drawn on the screen of FIG. A node object 81 is an image object representing a process. The node object 81 has a rectangular area representing the inventory quantity of the process, a rectangular area representing the producible quantity of the process, and a rectangular area representing the planned production quantity of the process. It is composed of a rectangular area whose height indicates the number of products that can be produced in the process. A flow object 82 is a strip-shaped image object representing a flow of providing products from process to process. The height of the flow object 82 represents the number of items provided between steps.

Referring to FIG. 10, the diagram display unit 2-1 acquires production capacity data 7 in step S401.

In step S402, the diagram display unit 2-1 plots the hierarchical level in the production capacity data 7 on the horizontal axis and the number of records for each hierarchical level on the vertical axis, and determines the position where the node object 81 of each process is drawn.

Further, the diagram display unit 2-1 sorts the records included in the production capacity data 7 by process key, hierarchy level, and child part number. The records of the production capacity data 7 are sorted in ascending order of the process key value, in ascending order of the hierarchical level value if they have the same process key, and in ascending order of the child part number value if they have the same hierarchical level. . The diagram display unit 2-1 executes a series of processes between steps S403a and S403b for all records in the sorted order.

In step S404, the diagram display unit 2-1 acquires from the production capacity data 7 the inventory quantity, producible quantity, planned production quantity, and planned production quantity of the deliverable product of the process of the record being processed, Node objects 81 are generated based on those numerical values, and these node objects 81 are mapped on the screen. At this time, the diagram display unit 2-1 displays the stock quantity, producible quantity, planned production quantity, and planned production quantity of the deliverables in the relevant process as elemental articles for producing the deliverables in the next process. is divided by the required number of deliverables of the process, and based on the obtained value, the relative height of the rectangular area corresponding to each numerical value is determined.

As shown in the portion surrounded by the encircling dashed line 92 in FIG. Since the height is determined, each rectangular area becomes a bar graph, making it possible to easily visually recognize the relationship between each numerical value.

Also, at this time, the relative height of the rectangular area is not determined by each numerical value of the product of the process, but the value obtained by dividing each numerical value by the required number used for the product of the next process. Since the relative heights are determined, it is possible to easily visually recognize the state of supply of articles between processes.

In addition, the diagram display section 2-1 is arranged in ascending order of hierarchical level in the direction from right to left on the horizontal axis of the screen, and arranged in ascending order of child part numbers in the direction from top to bottom on the vertical axis of the screen. .

In step S405, the diagram display unit 2-1 determines whether or not the planned production quantity for the process of the record being processed is smaller than the requested quantity minus the inventory quantity. If the planned production quantity is smaller than the value obtained by subtracting the stock quantity from the requested quantity, the diagram display unit 2-1 highlights the rectangular area of the planned production quantity of the node object as a bottleneck in step S406.

The highlighting may be, for example, displaying the area in a color distinguishable from other areas. Alternatively, the area may be surrounded by a thick encircling line. Alternatively, the area may be surrounded by an encircling line of a color different from that of the other areas. Alternatively, the area may be a blinking display that alternately switches between the first color and the second color. Alternatively, the character string representing the area may be displayed in a larger font than the character strings of the other areas.

Note that in FIG. 11, the rectangular area is highlighted by hatching of a diamond grid. In FIG. 11, the portion surrounded by the encircling dashed line 94 shows the node object 81 in which the planned production quantity rectangular area and the planned production quantity rectangular area are highlighted as bottlenecks.

In step S407, the diagram display unit 2-1 determines whether or not the planned production quantity of the process of the record being processed is smaller than the requested quantity minus the inventory quantity. If the planned production quantity is smaller than the value obtained by subtracting the inventory quantity from the requested quantity, the diagram display unit 2-1 highlights the rectangular area of the planned production quantity of the node object as a bottleneck in step S408.

In step S409, the diagram display unit 2-1 determines whether or not the producible quantity of the process of the record being processed is smaller than the planned production quantity. If the producible quantity is smaller than the planned production quantity, the diagram display unit 2-1 highlights the rectangular area of the producible quantity of the node object as a bottleneck in step S410.

In step S411, the diagram display unit 2-1 determines whether or not the producible quantity of the process of the record being processed is smaller than the requested quantity minus the inventory quantity. If the producible quantity is smaller than the value obtained by subtracting the inventory quantity from the requested quantity, the diagram display section 2-1 executes step S410.

At step S412, the diagram display unit 2-1 determines whether or not the rectangular area of the planned production quantity in the process of the record being processed is highlighted.

If the rectangular area of the planned production quantity is highlighted, the diagram display unit 2-1 connects the node object of the process and the node object of the process to which the process is moved in step S413. A flow object 82, which is a belt-shaped image object based on a cubic Bezier curve, is generated and highlighted as a bottleneck.

Note that in FIG. 11, the highlighting of the flow object 82 is indicated by hatching with horizontal stripes. In FIG. 11, the portion surrounded by the dashed line 95 shows that the flow object 82 from the process that does not satisfy the planned production quantity of the next process to which the deliverables are to be moved is highlighted. As a result, it is possible to easily confirm which part supplied from which process is in short supply.

Also, at this time, the height of the flow object 82 represents the number of outputs of the process. That is, the height of the flow object 82 is the sum of the height of the rectangular area of the inventory quantity and the height of the rectangular area of the planned production quantity in the node object 81 of the process.

On the other hand, if it is determined in step S412 that the rectangular area of the planned production quantity is not highlighted, the diagram display unit 2-1 becomes the node object 81 of the process and the destination of the process in step S414. A flow object 82, which is a belt-shaped image object based on a cubic Bezier curve connecting the current process node object 81, is generated and displayed semi-transparently. When a plurality of flow objects 82 are connected to one node object 81, the flow objects 82 overlap each other, but each flow object 82 can be visually recognized by translucent display. Looking at the portion indicated by the enclosed dashed line 91 in FIG. 11, the heights of the two flow objects are visible due to the translucent display.

In addition, when the same part is provided to one process from a plurality of preceding processes, the curves of the flow object 82 from those preceding processes do not overlap, but are in the portion surrounded by the encircling dashed line 93 in FIG. As shown, a plurality of flow objects 82 are arranged so as to touch each other.

In step S415, the diagram display unit 2-1 displays the planned production quantity, the inventory quantity, the planned production quantity, the output quantity, and the shortage quantity near each node object 81 or on the flow object 82. Draw each number.

In FIG. 11, the planned production quantity, the inventory quantity, the planned production quantity, and the output quantity of the relevant process are drawn as the numerical values, and the shortage quantity is drawn as a negative numerical value in parentheses.

Note that the screen shown in FIG. 11 is an example, and the present invention is not limited to this. In FIG. 11, numerical values of planned production quantity, stock quantity, planned production quantity, output quantity, and shortage quantity are drawn near the node object 81 or on the flow object 82. may be different screen displays. Alternatively, the numerical value may not be displayed on the screen. Alternatively, the numerical value may not be displayed on the screen normally, and when a certain point is designated by a mouse click or mouse-on, the numerical value at that point may be displayed. When numerical values are displayed, it is only necessary to visually recognize the number or excess/deficiency of element products and product products in each process, and display items, display positions, and display formats are not particularly limited. For example, in the vicinity of the node object 81, item names such as inventory quantity, producible quantity, planned production quantity, planned production quantity, and their numerical values may be displayed in a list.

FIG. 12 is a diagram showing another example of the screen displayed by the diagram display process. In the example of FIG. 12, unlike the example of FIG. 11, numerical values indicating the number of element products and product products in each process are not displayed. As shown in FIG. 12, the diagram display unit 2-1 may display a screen that does not include numerical values indicating the number of element items and product items. The diagram display unit 2-1 may display the screen of FIG. 11 and the screen of FIG. 12 so as to be switchable. Also, the diagram display unit 2-1 may display a screen as shown in FIG. 12 to display the numerical value of the process specified by mouse click or mouse on.
