Abstract

Data for production is input by and input device 3 and stored in a data base 1 for planning. Knowledge for planning is also input by the input device 3 and stored in a knowledge base 2 for planning. An inference engine 6 automatically makes and modifies the production plan. The plan made by the inference engine 6 is stored in a data base 17 of inference result. An intelligent editor 15 makes a plan free of inconsistencies through the input device 3. The inference result of planning of the intelligent editor is also stored in the data base 17 of inference result. Data in the data base 1 and in the data base 17 of inference result is either indicated on a display 16 or printed on paper by a printer 22. As a result, it is possible to make a reliable plan and realize planning having wide extent of utilization.
