机械产品CIMS环境下的设计成本测算的实现

Realization of the Design Cost Control Over Mechanical Products Based on CIMS

对产品技术成型 ,结构相对稳定的大型设备制造企业如何在事前———产品设计阶段进行成本控制问题进行了研究 ,提出了设计成本控制要经过的两个阶段 :即产品方案设计阶段和零件结构设计阶段 ,给出了每个阶段采取的不同成本测算方法及数学模型 ,并进行了案例计算。

The cost control in the course of products designing in large scale equipment manufacturers whose products are relatively mature and steady going is discussed in this paper.Generally,the design cost control can be separated into the cost control over project design,and cost control over stucture design.The different methods of rough estimate and mathematical models are presented.
