(Flowchart of production plan update processing)
FIG. 13 is a flowchart showing an example of production plan update processing according to one embodiment of the present invention.
In the above-described production plan creation process (FIG. 3), when the resource setting unit 201 sets the resource usage period for the newly received order information D1, in order to shorten the processing time, It does not consider the resource usage period for other orders that are For this reason, there is a possibility that the resource use periods of multiple orders will overlap.
Therefore, as shown in FIG. 13, the production planning device 2 adjusts the resource usage periods of all orders and executes production plan update processing to eliminate errors such as duplication.

First, the resource setting unit 201 determines whether or not a production plan update request has been received (step S20).
For example, the function setting unit 207 sets a function to transmit an update request to the resource setting unit 201 every time a user-specified time period (for example, one hour) elapses. Alternatively, an update request may be transmitted to the resource setting unit 201 when the user performs an operation for instructing update via the input device 3 .

If the resource setting unit 201 has not received an update request (step S20: NO), it waits until an update request is received.

When the resource setting unit 201 receives an update request (step S20: YES), the resource setting unit 201 executes processing for updating the resource use period (step S21).
For example, the resource setting unit 201 refers to the allocation information D7 (FIG. 9), and if there are resources whose resource usage periods overlap, the resource setting unit 201 assigns calendar information D5 (FIG. 7), shift information D6 (FIG. 8), By referring to the allocation information D7, resource operating days and periods not used by other orders are searched to eliminate duplication of resource use periods.
Further, for example, when the user performs an operation to change the resource use period via the input device 3, the resource setting unit 201 may update the resource use period according to the change operation.
Furthermore, the resource setting unit 201 may refer to the inventory information D8 (FIG. 10) and adjust the resource use period according to the amount of product inventory. For example, when the inventory amount of a product exceeds the upper limit, the number of inventory shipments is increased, and the resource use period is adjusted so that the use of resources for manufacturing the product is reduced. On the other hand, when the inventory amount of the product is equal to or less than the lower limit value, the resource use period is adjusted so that the number of inventory shipments is decreased and the use of resources for manufacturing the product is increased.
The resource setting unit 201 overwrites and updates the allocation information D7 with the updated resource usage period.

Next, the inventory amount calculation unit 202 calculates the inventory amount of each product by season based on the resource information D4 (FIG. 6) and the resource usage period recorded in the updated allocation information D7 (FIG. 9). is calculated (step S22). The inventory amount calculator 202 records the calculated inventory amount in the inventory information D8 (FIG. 10).

Next, the order Gantt chart creating unit 203, the resource Gantt chart creating unit 204, the resource load graph creating unit 205, and the inventory transition graph creating unit 206 generate the order Gantt chart, the resource Gantt chart, the resource load graph, and the inventory transition graph, respectively. is updated (step S23).

Next, the output data creation unit 208 creates output data D9 (FIG. 11) based on the function settings recorded in the setting file D10 (FIG. 12) (step S24). When the output data creation unit 208 creates the output data D9 based on each function setting, the production plan update process ends.
