Optimization Model Under Grouping Batch for Prefabricated Components Production Cost

During the prefabricated component (PC) production stage, for many kinds of PCs, production technologies are not the same. It is an important reason for high cost of PC production that reasonable group batch plan is lacked. By group technology and planning theory, an optimization model of grouping batch production for a variety of PCs is established. The model regards the minimum of the cost of production of PCs as the objective function. The size of the bottom mold, the type of embedded parts and connectors and the number of molds in the production process of PCs are constrains. By comparative analysis of application instance, the production cost under grouping batch for PCs is significantly reduced. It proves that the optimization model has a reference for production cost control under grouping batch for PCs.
