全球竞争环境下模糊的产品规划与设计具有重要的理论和现实意义。本项目将利用质量功能展开、供应商协同设计、模糊集、模糊规划和优化等理论，研究基于质量功能展开和供应商协同的模糊产品规划与设计问题。 研究的主要内容为：建立基于质量功能展开的新产品开发过程的模糊信息建模的理论与方法。建立基于质量功能展开和供应商协同的产品规划与设计的模糊建模和优化的理论与方法，并针对模型的特点以及为适应大规模优化问题的需要，设计相应的混合智能算法。根据基于质量功能展开和供应商协同的模糊产品规划与设计的理论和方法，开发基于质量功能展开和供应商协同的模糊产品规划与设计的决策支持系统。 研究内容的解决需要从理论上深入研究，也需要根据我国企业的实际情况探讨新理论、新方法的应用途径，以提升其产品的规划与设计水平。

Fuzzy product planning and design under a global competiitve enviroment has a great significance of theory and practice. This project will investigate a proplem of product planning and design based on quality function deployment (QFD) and supplier collaboration (SC) by using the theories of QFD, SC design, fuzzy set, fuzzy programming and optimization. The main contents will be investigated as following: a QFD-based theory and method of modeling fuzzy information of new product development will be proposed. A fuzzy theory and method of modeling and optimizing product planning and design based on QFD and SC will be proposed, and then a novel mixed intelligent algorithm will be designed to solve the proposed models according to the features of the models. According to the proposed theories and methods of fuzzy product planning and design based on QFD and SC, a decision support system of fuzzy product planning and design based on QFD and SC will be developed. Solving the research contents not only requires the in-depth invetisgation of theory, but also need to discuss the applications of the proposed novel theories and methods according to the actual instances of many corporations in China in order to advance the levels of product planning and design in the corporations.
