面向并行工程的DFC与DTC辨析.doc

面向并行工程的DFC与DTC 内容摘要：本文对面向成本的设计（Design For Cost）和按费用设计（Design To Cost）的思想进行了分析，指出DFC与DTC的不同之处主要在于：DFC是一种设计方法，DTC在很大程度上属于管理方法；DFC主动地运用各种方法降低产品的成本，而DTC是为了获得一个满足给定的目标成本并符合用户要求的设计。两者的相同之处主要体现在从设计入手考虑产品的全生命周期成本。从两者对成本的重视程度、对设计的改进和产生的时间顺序看，可以说DFC是DTC的进一步发展。 Content abstract: in this paper, the Design For Cost (Design For Cost) and Design (the Design To Cost) according To the Cost of the ideas are analyzed, and pointed out that DFC and DTC difference mainly lies in: DFC is a kind of Design method, DTC in largely management method; DFC and actively use various methods to reduce the cost of the products, and DTC are to get a satisfy the given target cost and meet the requirements of the user design. Both in common mainly from the design of the product whole life cycle cost into consideration. From the degree of attention to the cost, improvement of design and produce the time order of, can say DFC is the further development of DTC. 关键词：并行工程，按费用设计（DTC—Design To Cost），面向成本的设计（DFC—Design For Cost） Keywords: concurrent engineering, Design according To Cost (DTC - Design To Cost), Design For Cost (DFC, Design For Cost) 0、引言 0, the introduction 在当今时代，并行工程一直是研究的热点，在其中的DFX领域中存在着许多课题，如：面向制造的设计（DFM—Design For Manufacturing）、面向装配的设计（DFA—Design For Assembly）等，当人们把目光转向成本时却遇到了两个十分类似的概念，即DTC（Design To Cost）和DFC（Design For Cost），有的研究者将两者混淆了，本文从两者的异同之处进行了分析，希望对并行设计的研究工作起到有益的作用。 In todays era, concurrent engineering has always been the hot spot of the research, there are many issues in the field of the DFX, such as Design For Manufacturing (DFM, Design For Manufacturing), Design For Assembly (DFA - Design For Assembly), etc., when people are turning To Cost is met two very similar concepts, namely the DTC (Design To Cost) and the DFC (Design For Cost), some researchers will confuse the two, this article from the similarities and differences of the two place are analyzed, and hope that the study of concurrent Design work play a useful role. 1、按费用设计（DTC—Design To Cost） 1, according To Cost (
