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