Simulation and Optimization of Job Shop Scheduling for Dry Transformers Based on eM-Plant

摘要

The model of job shop scheduling to fabricate dry transformers is constructed by Object-oriented Petri Net (OPN) in this paper, the essential attributes and ways of all object classes are defined to judge if there is a deadlock in the system. The overall OPN model of job shop scheduling is built according to relations of event actions in the manufacturing system. Product processes in the job shop is simulated by eM-Plant software to reconstruct and optimize the manufacturing system at last.
