Abstract

PURPOSE:To control the order load when a production schedule plan is produced. CONSTITUTION:All orders of a production plan storage part 1 are piled on the load at a load piling part 2 and stored in a load piling storage part 5. The process ability information of a process ability data storage part 4 and the order load piling information are shown at an ability-load collation display part 5 together with the load control information. Both the starting date of each process and the production ending date set with the change of the production starting date of the order to be controlled are changed at a process starting date control part 11. Meanwhile the production starting date, the process starting date, and the production ending date are changed at a process lead time control part 8 based on the change of the order lead time. Thus the load is controlled.

Further, in order to adjust the load of the specified order, the order lead time of the specific order is input from the order lead time change instruction input unit 6, and the order lead time changing unit 7 applies the corresponding value to the production plan storage unit 1. Change the order lead time of the order. The process lead time adjustment unit 8 changes the process lead time of each process of the corresponding order in the production plan storage unit 1 so as to be proportional to the rate of changing the order lead time, and uses the changed process lead time to start the process. After changing the date and time, the load stacking unit 2 is activated again. 2A and 2B are explanatory views showing the data structure. FIG. 2A shows the order configuration stored in the production plan storage unit 1 of FIG. 1, and the configuration data includes process lead times of all processes for all orders for which a production plan is to be created. It is the sum of the order lead time, the manufacturing start date and time and the manufacturing end date and time of the order, the process start date and time at each process, the load, and the process lead time. FIG. 2B shows the structure of the data stored in the process capability data storage unit 4 of FIG. 1, and stores the process capability for each time bucket divided for a certain period for each process. FIGS. 3A and 3B are explanatory views showing load adjustment of the order. FIG. 3A shows the change of the process start date and time and the manufacturing end date and time of each process of the relevant order, which is performed by the process start date and time adjustment unit 11 of FIG. The manufacturing end date and time and the process start date and time of each process are moved in parallel by the change in the manufacturing start date and time. FIG. 3B shows the process lead time, the process start date and time, and the process start date and time when the order lead time is changed without changing the manufacturing end date and time of the corresponding order, which is performed by the process lead time adjusting unit 8 in FIG. It represents a change in the start date and time. First, the process lead time of each process is changed at the changed rate of the order lead time. Next, for all the processes, the sum of the process lead times from the corresponding process to the final process is subtracted from the manufacturing end date and time to obtain the process start date and time. Further, the changed order lead time is subtracted from the production end date and time to obtain the production start date and time. At this time, the load per unit time is changed and the load is adjusted by changing the process lead time. Since the production end date and time are fixed and the order lead time is changed, the delivery date can be kept.

Process capability data storage unit, (C) load pile unit for accumulating a load per unit time obtained by dividing the load of the order by the process lead time for each time bucket, (D) A load heap storage unit that stores a cumulative load that is a value accumulated in the load heap unit for a time bucket, (E) compares the process capacity of the process capacity data storage unit with the accumulated load of the load heap storage unit A capacity-load comparison display section, which is displayed as (F) An order lead time change instruction input section for designating a specific order from the above orders and for inputting the change of the order lead time, (G) Designation An order lead time changing unit that changes the order lead time of the order to an input value from the order lead time change instruction input unit, (H) when changing the order lead time by fixing the manufacturing start date and time, The process lead time for each process is changed in proportion to the change in the order lead time, and the process start date and time of each process is the sum of the process lead time from the start process to the corresponding process and the manufacturing start. When changing to a value obtained by adding the date and time, changing the manufacturing end date and time to a value obtained by adding the order lead time to the manufacturing start date and time, and fixing the manufacturing end date and time to change the order lead time, The process lead time for each process is changed in proportion to the change in the order lead time, and the process start date and time of each process is changed to the corresponding process. To the final process, the sum of the process lead times is changed to a value obtained by subtracting the manufacturing end date and time, and the production start date and time is changed to a value obtained by subtracting the order lead time from the production end date and time. A process lead time adjusting unit for activating, (I) a manufacturing start date / time change instruction input unit for inputting a change of the manufacturing start date / time by designating a specific order from the orders, (J) the specified order A manufacturing start date / time changing unit that changes the manufacturing start date / time of the production plan storage unit to an input value from the manufacturing start date / time change instruction input unit, (K) when changing the manufacturing start date / time, the manufacturing end date / time is A process start date and time adjustment unit that changes the production start date and time, changes the process start date and time for each process by the production start date and time, and activates the load stacking unit. A manufacturing schedule planning adjusting device characterized by the above.
