Abstract:
A production/manufacturing planning system comprising:a production planner configured to output a planning result after performing production planning for a whole factory having a plurality of manufacturing lines that are configured to produce a plurality of kinds of products; a manufacturing scheduler configured to provide, at least in part based on said planning result outputted from said production planner, a manufacturing planning schedule relative to each of the manufacturing lines for each kind or product being produced by each of the manufacturing lines, said manufacturing scheduler being provided in each of said manufacturing lines; a line capability grasping simulator configured to simulate product delivery quantities as quantities of products produced by each of said manufacturing lines and to provide simulated result data for predicting future product delivery quantities; a process control system configured to control the progress of a plurality of processes being preformed in each of said manufacturing lines and to provide, for each manufacturing line, historical information data including past record data for each of said products produced by each of said manufacturing lines, said process control system being provided in each of said manufacturing lines, and a scheduled past record control system configured to determine whether it is likely that there will be a probable future failure of any of the manufacturing lines to process and deliver planned quantities of products with respect to said manufacturing planning schedule and to give an alarm when the scheduled past record control system determines it is likely that the probable future failure will actually occur and to provide a change of a parameter being used to perform production planning for the whole factory to said production planner when the alarm is given so as to prevent said probable future failure from actually occurring, the scheduled past record control system determination being at least in part based on said historical information data of said process control system and said simulated result data of said line capability grasping simulator.
