摘　　要：为了将产品成本估算引入到产品的并行设计过程中,实现产品成本评估与产品设计的同步推进,达到降低产品成本的目的,论文探讨了并行工程的产品开发过程,提出了在并行工程环境下对产品进行成本估算的方法,即基于产品结构树的快速成本估算法和基于材料消耗的详细成本估算法。研究表明将产品成本评估引入到产品设计中,在产品设计的不同阶段对产品成本进行估算,及时向设计人员反馈产品成本信息,可以保证所设计的产品在满足用户性能需求的同时又具有较高的经济性。Cost evaluation was synchronized with the product development process by introducing cost estimates into the concurrent product development process. Engineering methods were developed for concurrent product development cost estimates. The cost estimation methods include a quick cost estimation method based on the product structure tree and a detailed cost estimation method based on material consumption. Product cost estimates at different design stages with feedback to designer can assure that the product design has high quality as well as good economics. 
