Considering the gap between academic research and real world application, the characteristic of manufactories of "much variety and little batch", this paper discusses the abstraction and modeling of the workshop performance using colored Petri net characterizing definite description of DEDS. And rule bases are applied into the model to tackle the dynamic events and disturbances with dynamic scheduling. After analysis on agile response of MES and integration of its scheduling model, by adopting distributed component technology the workshop scheduling model was capsulated as a scheduler to realize the scheduling module of MES easier to be integrated and rapidly reused. Finally a prototype of scheduler is proposed.
