Automatic machining scheduling method based on an expert system

摘要

An automatic machining scheduling method based on an expert system is provided, which can optimize and facilitate the assignment of processes in a large-scale production system to individual machine tools, based on expert experience accumulated as a database, thereby enabling effective operation of the production system. When requested quantities for respective machine models to be produced are input (S1), the machining time of each jig involved in a respective machine model and the usage form of each jig are read from the related files, and the former is multiplied by the latter, to obtain the total machining time for each of the machine tools (S2, S3). A day or week production matrix is created based on the ratio of the calculated time of each of the machine tools to the operating time thereof per day (S4-S7). It is determined whether a machining schedule including a pattern identical to the machining pattern of the matrix is registered (S10, S11). If the machining schedule is registered in the file, the registered schedule is used (S12-S15).
