An Improved Fuzzy Approach to Planning and Scheduling Problems in Hybrid Distributed MES

摘要

This paper proposes an improved approach which based on the model dealing with uncertain processing times, flexible due-dates and input-output radio. Associating with fuzzy set, classic scheduling rules, multi-closed loop control and user cooperating, hybrid system problems are hierarchically decomposed into the planning level problems, the scheduling level problems and material tracking feedback level problems.
