Actualizing low cost strategy, reducing production and operating costs, improving efficiency of capital appreciation is not only the eternal topic of enterprise management, but also the fundamental goal to pursue for enterprise production and capital operation. Facing to the fierce market competition, the auto enterprises of our country should focus on improving new product development capabilities and cost competitiveness. As continuing improvement to independent research and development of our country's auto enterprises, in the processing of new product development, how to effectively control costs and improve profitability is significant for improving the market competitiveness of new products.Research shows that although the investment cost of product design stage is only about 5% of the total cost, it decides more than 70% of product cost. Therefore controlling cost should focus on the product design stage, this paper presents the research topic about cost control for the design stage. The research emphasis is cost estimating of parts and cost control techniques in the design stage.First of all, the paper analyzes the content of cost control in product design stage, including: cost estimating analysis and cost control, the former services for the latter. Then the research status of cost control is introduced.Secondly, this paper gives a detailed study about cost estimation in the design stage, and for different part characteristics and different design stages, two cost estimating methods are proposed: one is based on integrated similarity that is used to estimate the cost of similar parts in the concept design stage; the other is based on ABC which solves the cost estimation problem of new parts and detailed design stage.Then, in order to control and manage product cost, the paper introduces objective cost management into the design stage of new products. This chapter introduces the theory of objective cost management in detail, focuses on the study about the decomposition method of objective cost. The concept of ameliorative rate is proposed in order to analyze economy of parts and get the priority of cost control. Combining the value engineering and DFC, a unique checklist about specific parts is designed which can inspire designers to look for measures of cost reduction.Finally, some related researches on the overall framework of cost control software system are done; the overall requirement analysis and network integration solutions of system are given. A software system about cost control for design phase is developed...
