Research on Shop Scheduling and Adjustment of Production Planning Problem Based on MES

For the high complexity problems of unequal distribute production capacity in workshop,the paper analysised the task allocation and control structure in workshop based on manufacturing execution system(MES),established production capacity matrix according to the production capacity of different working centers,and set up manufacturing capacity needs matrix according to the statistical of capacity needs for components manufacturer.Balance analysis model for workshop production capacity requirements planning and actual balance of production capacity was established.Mathematical model for calculating deviation of production capacity is established to analyze the coordination of capacity requirements and actual production capacity,and to analyze uncertainties of the production capacity distribution in discrete manufacturing workshop.Finally,application example about the model used in workshop program management and capacity balance management is given.
