中文摘要：

基于先进的设计开发理论理念，结合企业新产品开发流程及企业新产品开发的实际情况，为了提高设计效率，通过对发明问题解决理论（TRIZ）、质量功能配置理论（Quality Function Deployment-QFD）、价值工程理论（Value Engineering-VE）等设计方法的研究和应用，提出了集成QFD、VE、TRIZ理论的面向成本的新产品研究开发系统QVTS。系统规范了从设计需求分析到设计方案提出等过程的设计流程，给出了各阶段解决具体问题的方法和工具。对于实现产品设计方案的技术经济综合优化、降低产品成本和提高产品竞争力有着十分重要的意义。

英文摘要：

A new product development system, cost oriented QVTS with integrated QFD, VE and TRIZ theory is put forward based on the research and application of TRIZ innovation theory, quality function development theory and value engineering theory and process of new product development of enterprise to improve the design efficiency. Design process is normalized from the analysis of design needs to design plan working out. Then methods and tools for solving the problems of all the phases are put forward. The system is important to the optimization of the design plan at the aspects of technical economy, cost cutting and com- petitive power improvement.
