【摘要】 随着经济全球化的发展，全球市场正在逐渐形成并不断地发展，在最短的时间内以最低的成本生产出高质量的产品已成为制造商的竞争焦点。并行工程技术正体现了这种思想，人们不断地开发并行工程的支持工具DFX(Design for X)，如面向制造的设计DFM(Design for manufacture)，面向装配的设计DFA(Design for assemble)等，这些工具的应用在缩短产品开发周期方面取得了成效，但是在产品成本降低方面没有实质性的进展。在实际中，产品设计人员对于产品成本的知识通常掌握不多。为此，研究设计过程中产品成本的估算方法、预测理论以及降低产品成本的设计方法，实现产品设计方案的技术经济性综合优化，对于降低产品成本，提高其市场竞争力具有十分重要的意义。 在对国内外产品成本估算方法研究的基础上，本文的工作主要从以下四个方面展开。第一，研究面向成本设计的概念和关键技术，面向产品全生命周期分析影响产品成本的各项因素；第二，建立基于功能的产品成本估算模型，以适应“自顶向下”的现代产品的设计理念，将产品成本与产品结构在功能这一概念上得到统一；第三，在基于功能的产品成本估算模型的基础上，提出了基于功能的产品成本两级估算方法，此方法可用于产品设计全过程中产品成本的估算；最后，以浙江工业大学硕士学位论文摘要Solidworks为开发平台，Delphi为编程工具，初步构建了基于功能的产品成本估算系统，验证了本文估算方法的实用性和可行性。更多还原

【Abstract】 With the development of economic globalization, the global market is taking shape gradually and developing constantly, and producing the high-quality products with the lowest costs within the shortest time has already become the manufacturers’ competition focus. Running side by side engineering technology reflects this thought, people constantly develop the support tool DFX(Design for X), such as design for manufacture, design for assembly, etc. The application of these tools has made some effects in shortening the products’ development cycle, but there is no substantive progress in reducing of the cost of the products. In reality, the products’ designers don’t usually grasp enough knowledge of products’ cost. Therefore, studying the estimating method and predicting theory of products’ cost in design process as well as the design method for reducing the products’ cost and realizing the technologically economically synthetic optimization for products’ design plan have very important meaning in reducing the products’ cost as well as improving its market competitiveness.Based on the study of the domestic and international products’ cost estimating method, the paper spreads out from four following respects. First, study the concept and the key technology for DFC and analyze every factor influencing the products’ cost within the products’ life cycle; second, set up the estimating model of products’ cost based on the function to meet the modem products’ design idea of the "top-down", unifying the products’ cost and structure on this functional concept; third, based on the functionally estimating model of the products’ cost, propose two grades of products’ cost estimating method based on the function . The method can be used in the cost’ estimation in the whole course of product design; finally, regarding Solidworks as the developing platform, Delphi as the programming tool, structure a based on function-based products’ cost estimating system to tentatively prove the practicability and feasibility of this text’s estimating method.更多还原
