A knowledge based system for combined just-in-time and material requirements planning

Abstract A knowledge based simulation model for combined Just-in-Time/Material Requirements Planning systems is presented. The model written in PROLOG includes two expert systems, one for Kanban logic and the other for job shop control. The model is applied to an electronics assembly plant. Factors related to demand variability, vendor lead time variability and buffer sizing are examined. Knowledge based simulation modeling is found to be an effective approach for examining such combined systems in a real world environment.
