Specifically, the control unit 12 reads a program stored in the storage unit 13 and expands it in the memory 122, and causes the CPU 121 to execute instructions included in the program expanded in the memory 122. And the control part 12 reads / writes data with respect to the memory 122 and the memory | storage part 13 according to the execution result of the command by CPU121, or controls operation | movement of the communication part 11 grade | etc.,.

  The storage unit 13 includes a nonvolatile storage device such as a magnetic storage device or a semiconductor storage device, and stores various programs and data. The program stored in the storage unit 13 includes an analysis support program 131. The data stored in the storage unit 13 includes node data 132, critical path data 133, and production condition data 134.

  Note that some or all of the programs and data to be stored in the storage unit 13 in FIG. 1 are stored in another device with which the analysis support apparatus 10 can communicate via a network, and the analysis support apparatus as necessary. 10 may be downloaded. Also, some or all of the programs and data to be stored in the storage unit 13 in FIG. 1 may be stored in a storage medium and read by the medium reading unit 16 as necessary.

  The analysis support apparatus 10 implements various functions for supporting supply chain analysis by causing the control unit 12 to execute the analysis support program 131. The functions for supporting supply chain analysis include, for example, a function for visualizing the cost and time of each node constituting the supply chain, a function for calculating a critical path, and the like.

  FIG. 2 is a block diagram showing a configuration of the analysis support program 131. As shown in FIG. 2, the analysis support program 131 includes a node data editing unit 131a, a critical path calculation unit 131b, a visualization unit 131c, and an analysis support unit 131d.

  The node data editing unit 131a provides a function of editing the node data 132 that is data related to the nodes constituting the supply chain. The critical path calculation unit 131b provides a function of obtaining a critical path that is the most time-consuming path among the paths connecting the nodes. The visualization unit 131c provides a function of visualizing the supply chain in an easily understandable format such as a graph. The analysis support unit 131d provides a function of supporting analysis for improving the supply chain.

  Next, the operation of the analysis support apparatus 10 will be described with reference to a specific example. FIG. 3 is a flowchart showing the operation of the analysis support apparatus 10. The operation shown in FIG. 3 is realized by the control unit 12 executing the analysis support program 131.

  As shown in FIG. 3, first, the control unit 12 edits the node data 132 representing the supply chain to be analyzed according to the function provided by the node data editing unit 131a (step S101). Here, the node data 132 will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram illustrating an example of a supply chain. FIG. 5 is a diagram illustrating an example of node data 132 corresponding to the supply chain illustrated in FIG.

  As shown in FIG. 4, in this embodiment, the supply chain is configured with a process in which some work is performed and a purchased product used in the process as nodes. For example, if supplier A purchases and processes material B, delivers it to our company and assembles it in our assembly process C, material B is registered as a node indicating the purchased product, and processing process at supplier A And our assembly process C is registered as a node indicating a different process. A node Np indicating a process is connected to one or more nodes Np corresponding to the next process by a link L. The node Ni indicating the purchased item is connected by a link L to a node Np indicating a process in which the purchased item is used.

  As illustrated in FIG. 5, the node data 132 includes items such as a node code, a node name, a node type, a time, a cost, and a connection destination node code. The node code is a unique number for identifying the node. The node name is the name of the node. The node type indicates whether the node is a node indicating a process or a purchased item.

  Time is the time required by the node. The time required for a node is the time required for work in the process when the node indicates a process, and the lead time required from ordering to delivery when the node indicates a purchased product. The cost is a cost required by the node. The cost required by a node is the cost of equipment and personnel required for work in the process when the node indicates a process, and the purchase cost when the node indicates a purchased product.

  The connection destination node code is the node code of the connection destination node. The connection destination node is a node corresponding to the next process when the node indicates a process, and a node indicating a process in which the purchased product is used when the node indicates a purchased product. If the node is a node indicating a process and there are a plurality of next processes, the connection destination node code 1, the connection destination node code 2, the connection destination node code 3, and the like according to the number of the next processes. Several items are provided, and node codes of nodes indicating the next process are set one by one.

  Note that the editing of the node data 132 may be realized, for example, by a method in which a user inputs a value on a screen that displays the contents of the node data 132 in a table format as shown in FIG. It may be realized by a method of creating a flow diagram as shown in FIG. In the case of a method for creating a flow diagram, the connection destination node code is set based on the link L connecting the nodes. Moreover, time and cost are set based on the value input with respect to the input item on the pop-up screen displayed, for example when a node is selected.

  When the editing of the node data 132 is completed, the control unit 12 obtains a critical path according to the function provided by the critical path calculation unit 131b, and stores the obtained critical path in the storage unit 13 as the critical path data 133 (step S102). . The critical path is a path having the largest total time of included nodes among paths connecting the end nodes of the supply chain according to the connection destination node code. The total time of the nodes included in the critical path corresponds to the time required for the entire supply chain. The search for paths included in the supply chain can be realized by using a known algorithm such as a depth-first search.

  FIG. 6 is a diagram illustrating an example of the critical path data 133. As shown in FIG. 6, the critical path data 133 includes items such as an arrangement order, a node code, a node name, and a critical path. The arrangement order indicates the order in which the paths are rearranged when the supply chain is visualized. The arrangement order is set so that the value of the node included in the critical path is smaller than that of the node not included in the critical path. The arrangement order is set so that the value becomes smaller as the node is closer to the start point of the path.

  The node code is a unique number for identifying the node. The node name is the name of the node. The critical path is set to “Yes” when the node is included in the critical path, and is set to “No” otherwise.

  Subsequently, according to the function provided by the visualization unit 131c, the control unit 12 visualizes information on the nodes included in the supply chain based on the node data 132 and the critical path data 133, and displays the information on the display unit 14 (step S1). S103). The control unit 12 visualizes the information regarding the node in various formats according to the user's specification. Examples of visualization of information regarding nodes are shown in FIGS.

  FIG. 7 is a diagram illustrating an example of displaying information regarding nodes as a flow diagram. As shown in FIG. 7, in the flowchart, a node indicating a purchased item and a node indicating a process are displayed using different graphics, and are connected by a link based on a connection destination node code. In addition, the time and cost of the node are added to the graphic corresponding to the node and displayed. When displaying the information about the node as a flow diagram, the control unit 12 displays the nodes included in the critical path in approximately one column near the center based on the critical path data 133. Further, the control unit 12 emphasizes the link connecting the nodes included in the critical path, for example, by changing the color or changing the thickness. By displaying the flow diagram in this way, the user can easily understand which node constitutes the critical path.

  FIG. 8 is a diagram illustrating an example in which information regarding nodes is displayed as a Gantt chart. As shown in FIG. 8, in the Gantt chart, each node is represented as a bar having a width corresponding to the length of time, and the bars are connected by arrows based on the connection destination node code. By displaying the Gantt chart in this manner, the user can easily understand the length of time and the context of each node.

  The control unit 12 can rearrange the nodes based on the values of the items in the arrangement order of the critical path data 133 when displaying the information about the nodes as a Gantt chart. FIG. 9 is a diagram illustrating an example of a Gantt chart in which the nodes are rearranged based on the values of the items in the arrangement order. As shown in FIG. 9, by rearranging the nodes based on the values of the items in the order of arrangement, the user can easily understand how the required time for the entire supply chain is determined.

  FIG. 10 is a diagram illustrating an example in which information regarding nodes is displayed as a bar graph and a stacked graph. In the example illustrated in FIG. 10, a graph related to the cost of the node and a graph related to the time of the node are displayed separately. In the graph relating to the node cost, a bar graph in which the cost of each node is individually represented by a bar and a stacked graph in which the integrated value of the cost of each node is represented by a line are displayed in an overlapping manner. Moreover, in the graph regarding the time of a node, the bar graph which represents the time of each node individually with the bar | burr, and the stacked graph which represents the integrated value of the time of each node with a broken line are displayed by overlapping. In this way, by displaying information about nodes as bar graphs and stacked graphs, users can easily compare the high cost of a node, the length of time, and the ratio that they occupy with other nodes. be able to.

  The control unit 12 can rearrange the nodes based on the values of the items in the order of arrangement of the critical path data 133 when the information about the nodes is displayed as a bar graph and a stacked graph. FIG. 11 is a diagram illustrating an example of a bar graph and a stacked graph in which nodes are rearranged based on the values of items in the arrangement order. As shown in FIG. 11, by rearranging the nodes based on the values of the items in the arrangement order, the user can increase the cost of the nodes included in the critical path, the length of time, and the ratio of them to the whole. Can be easily compared with other nodes.

  In the graph relating to the node time shown in FIG. 11, the stacked graph is displayed only for the nodes included in the critical path. By displaying in this way, the integrated value of time can be prevented from exceeding the required time of the entire supply chain.

  Note that the visualization format based on the functions provided by the visualization unit 131c is not limited to the examples illustrated in FIGS. The visualization format may be another format such as a PERT diagram, for example.

  After visualizing the information about the node, the control unit 12 supports the analysis of the supply chain by the user according to the function provided by the analysis support unit 131d. Specifically, the control unit 12 first receives a user input (step S104). When the received input is to change the cost of the node (step S105, Yes), the control unit 12 calculates the time of the node after changing the cost (step S106). Then, the control unit 12 updates the value of the cost and time of the node in the node data 132 (Step S107), and re-executes Step S102 and the subsequent steps. As a result, changes in the cost and time of the node are reflected in the graph or the like.

  When the received input is to change the time of the node (step S105, No, step S108, Yes), the control unit 12 calculates the cost of the node after the time is changed (step S109). Then, the control unit 12 updates the value of the cost and time of the node in the node data 132 (Step S107), and re-executes Step S102 and the subsequent steps. As a result, changes in the cost and time of the node are reflected in the graph or the like.

  When updating the node data 132, the node data 132 can be returned to the state before the update when the user performs a predetermined cancel operation by storing the update history or the difference data in the storage unit 13. Is preferred.

  When the received input is an instruction to end the process (step S108, No, step S110, Yes), the control unit 12 ends the operation illustrated in FIG. When the received input does not instruct the end of the process (No at Step S110), the control unit 12 re-executes Step S104 and subsequent steps in order to receive the next input.

  FIG. 12 is a diagram illustrating an example of analysis support by the analysis support apparatus 10. In the example shown in FIG. 12, a graph relating to the cost of the node, a graph relating to the time of the node, and a Gantt chart are displayed by visualization.

  In this state, it is assumed that the user performs an operation of selecting and pulling down one upper end of the bar of the node displayed in the cost graph. In this case, the control unit 12 determines that the cost of the node has been reduced to a value corresponding to the position where the upper end is lowered, and calculates the time of the node after the cost has been reduced. Then, the control unit 12 reflects the changed cost and time in the graph and the Gantt chart. Specifically, when the cost is lowered, the time required for the node is increased correspondingly, so that the time for the node increases in the graph and the Gantt chart relating to the node time.

  When the nodes are rearranged and displayed based on the critical path data 133, the critical path is switched by changing the time and cost of the nodes at a certain level or more, and the display order of the nodes is changed. For example, if you lower the cost of a node that is not included in the critical path, the time of that node increases, and at a certain stage, the path that includes that node becomes a new critical path, and the display order of the nodes changes. Change. Further, when the time of a node included in the critical path is lowered, the cost of the node increases, and at a certain stage, another path becomes a new critical path, and the node display order changes.

  In this way, the analysis support apparatus 10 updates the contents to be visualized in conjunction with the operation on the visualized information. By such linkage, the user can analyze the cost and time of each node while confirming the influence. For example, by reducing the cost of a node that is not included in the critical path within a range where the critical path does not change, the user can reduce the cost of that node without increasing the time required for the entire supply chain. Can be analyzed.

  In this example, the node value is changed by lowering the upper end of the bar of the bar graph. However, the node value can be changed by operating on the visualized information other than the bar graph. May be. For example, the value of the node may be changed by selecting each vertex of the stacked graph and raising or lowering it, or moving the right end or left end of the Gantt chart to the left or right. Further, when a bar or the like of a bar graph is selected, a pop-up screen may be displayed, and the cost and time may be input numerically in the form of a pop-up screen.

  The time of the node and the calculation of the time in step S106 and step S109 are performed based on various parameters included in the production condition data 134. In the production condition data 134, for example, parameters indicating the following production conditions are stored.

NW: Number of workers [people]
WHr: Scheduled work time [H / (person / month)]
WHo: Overtime work hours [H / (person / month)]
PCf: fixed process cost [yen / month]
PCv: Process variation cost [yen / month]
= Process operating time [H / month] x Operating cost per hour [yen / H]
LCf: Fixed labor costs [yen / month]
= Number of workers [person] x fixed labor cost per person [yen / (person / month)]
LCr: Artificial expenses on time [yen / month]
= NW x WHr x On-time artificial costs [yen / H]
LCo: Artificial overtime [yen / month]
= NW x WHo x Overtime artificial expenses [yen / H]

  Here, although the value per month is used as a parameter, values such as per year, per day, and per hour may be used as parameters according to the actual situation of the supply chain.

  Here, assuming that the number of units produced per month is n [units / month], the cost per unit is calculated by the following equation (1).

  If the required man-hour per vehicle is w [H / vehicle], the required time per vehicle is calculated by the following equation (2).

  If the cost or time of the node is changed, respond by changing the number of workers (NW) and overtime work time (WHo) included in the above parameters and formulas (the process operation time also changes in conjunction) Search for cost or time. Usually, the upper limit of the overtime work time is determined, and since it is managed in units of 1 hour or 0.5 hour, it is preferable to change the overtime work time according to such a situation.

  Since the data is discontinuous, the nearest cost or time is selected. In addition, a plurality of solutions may be generated depending on the combination of the number of workers and the overtime work time. In such a case, a solution with the shortest time or a solution with the lowest cost is selected.

FIG. 13 is a diagram illustrating an example of a relationship between node cost and time. The graph shown in FIG. 13 is a plot of data created under the following conditions.
Process fixed cost: 100,000 [yen / month]
Operating cost per hour: 100 [yen / H]
Number of workers: 1-10 [person]
Fixed labor costs per person: 100,000 [yen / (person / month)]
Regular working hours: 160 [H / (person / month)]
Artificial expenses on time: 1,250 [yen / H]
Overtime work hours: 0 to 45 [H / (person / month)]
Overtime artificial expenses: 1,625 [yen / H]
Monthly production n: 0.42 [units / month]
Man-hour required per unit w: 1,000 [H / unit]

  Instead of using the above equations (1) and (2), the following equation (3) is used to simply calculate the time corresponding to the changed cost or the cost corresponding to the changed time. Also good.

  Here, the standard hourly unit price [yen / H] is the above process variable cost [yen / month], fixed labor cost [yen / month], on-time artificial cost [yen / month], and overtime artificial cost [yen / month] ] To calculate the cost converted per hour. The standard unit price is, for example, the cost obtained by converting the total of process variation costs, fixed labor costs, on-time artificial costs and overtime artificial costs per hour for all combinations of the number of workers and overtime hours that can be taken, and the average It can be obtained by calculating the value.

  The above equation (3) is inversely proportional to the cost as a variable, and the changed cost or time can be easily calculated. However, when using equation (3), it should be noted that the data is continuous and may take a value that cannot be originally obtained. This problem is addressed, for example, by a method of using rough calculation using the equation (3) and calculating strictly by the method using the equations (1) and (2).

  As described above, in this embodiment, since the contents to be visualized are updated in conjunction with the operation on the visualized information, it is possible to provide good operability to the user.

  In addition, the structure shown in said Example can be suitably changed in the range which does not deviate from the summary of this invention. For example, the analysis support apparatus 10 may be configured to display information on a display unit included in another information processing apparatus. In this case, the displayed information is provided to another information processing apparatus as, for example, HTML data.
