摘　　要：针对大型离散制造企业产品结构特点,提出产品的自制件、外购件、原材料和工艺的多级综合结构模型.为了实现产品设计成本的优化控制,建立产品结构与或树的配置模型,并通过定义产品组成子件之间的相关性表示产品满足工艺需求的可制造性.基于单级产品结构与或树给出产品设计成本优化模型,采用仿真示例进行验证.仿真结果表明,所提出的DFC的模型Opt-BOMP较之DTC模型能够获得成本更优的产品设计方案.Opt-BOMP充分考虑了用户对产品的质量需求、供应商对外购物料的影响、产品的工艺要求、产品设计和生产的结合,能够增强产品设计的可行性.With respect to the characteristics of product structure in large discrete manufacturing enterprise, a multiple level product structure which integrated self-made items, outsourcing parts, raw materials and making processes was proposed. Afterwards, aiming at the optimization and control for product design cost, a product and/or tree structure based on configuration model was established, in which the assembly feasibility satisfying the requirements of an item making process was represented by the definition of correlation between its components. Based on the single level product and/or tree structure, a design cost optimization model was then given. Simulation experiments were employed to demonstrate its effectiveness. The experiments showed that the proposed Opt-BOMP on model DFC can achieve a better cost product design than the DTC model. The OptBOMP has considered the quality requirements of a product, the impact of supplier on outsourcing materials, the technology requirements of a product and the combination of product design and manufacturing, it can improve the feasibility of a product design.
