Discrete Production System Difficulties Different type of products needs different production process, needs different layout of equipments>Product change,layout changes The production proportion of different type of products often changes workforce organizing,equipments arranging production scheduling are very difficult and needs to adjust continuously. The requirement of production capacity is dynamic,the load- balance and the synchronization of production process are very difficult but necessary. Annual plan for production is usually inaccurate,however,the short plans such as monthly and weekly plans are the keys.Difficulties Different type of products needs different production process, needs different layout of equipments>Product change, layout changes The production proportion of different type of products often changes > workforce organizing, equipments arranging , production scheduling are very difficult and needs to adjust continuously.
