摘　　要：模具生产过程具有离散化定制的特点,使得在质量和产量约束下的准时交货较为困难.结合准时制与动态规划设计了一种多级调度算法及相关系统,将调度问题从车间排产扩展到整个产品生产流程,并从信息建模出发建立了各模型的关联关系,以便更完全地分配企业生产资源,均衡开展生产,从而缩短订单的生产周期.根据试验及初步应用验证,系统可以有效解决企业的离散化定制产品的调度问题,缩短订单的生产周期.The mold production process has the characteristic of the discrete customization, which makes it difficult to deliver the goods on time due to the restriction of quality and production. Combining JIT （just in time） and dynamic programming, a multilevel scheduling algorithm and the related system are designed. The scheduling algorithm extends the scheduling problem from the shop floor to the entire production process, and establishes the relationship of the model from information modeling, which makes the allocation of production resources more fully, and balances development of production, so as to shorten the production cycle of orders. According to the experimental study and preliminary application verification, the system can effectively solve the enterprise discretization constant product scheduling problem, and shorten the production cycle of orders.
