生产成本是工程和管理分析的重要绩效指标。尽管成本分析在整个产品开发周期中具有明显的相关性，但它并没有成为设计工程师关注的焦点。在某种程度上，这是因为对成本的一些关键误解——工程师没有接受过将制造成本与他们更熟悉的技术和设计参数联系起来的技术培训。虽然有许多人呼吁在工程和经济分析之间建立更密切的关系，但这些关键的概念障碍，加上现有计算工具的限制，限制了将成本分析纳入产品和过程开发。本文总结了需要克服的概念限制，并提出了修改过程成本分析概念的基础。此外，它提出了一系列成本分析案例，这些案例证明了“环境”的概念是有效使用工程成本估算的核心。
Production cost is a vital performance metric for engineering and management analysis. Despite its obvious relevance throughout the product development cycle, cost analysis has not been a focus of the design engineer. In part, this is because of some key misunderstandings of what cost is-engineers have not been trained in the techniques that tie manufacturing cost to the technical and design parameters with which they are more comfortable and familiar. While there have been many calls for a closer relationship between engineering and economic analysis, these key conceptual obstacles, in conjunction with the limits of the computational tools available, have limited the integration of cost analysis into product and process development. This paper summarizes the conceptual limitations that need to be overcome and presents a basis for revising the notion of process cost analysis. Moreover, it presents a series of cost analysis cases that demonstrate the way in which the notion of “context” lies at the heart of effective use of engineering cost estimates.
