Abstract: To solve the conflict between the customization,technology improvement and commonality in product development,a modular design method for multi-strategies was proposed.The Quality Function Development (QFD) method for multi-strategies was introduced to build the distribution model and evolution model of the main parameters.The functional module partition method based on flow principle was used to divided modules preliminarily.Aiming at the relationship between multi-strategies design analysis modules and main parameters,the partitioning principle and the instance design principle were proposed to evaluate the initial module partitioning result.The effectiveness and feasibility of the method were verified by a case study of modular design for a refrigerator product family.

Key words: product multi-strategies, modular design, module partition method

摘要： 为解决机电产品开发中客制化、技术进化和通用化三种策略之间的矛盾,提出机电产品多策略模块划分方法。该方法首先采用多策略质量功能展开方法,构建主参数分布模型和演进模型|其次采用基于流准则的功能模块划分方法初步划分模块|然后针对多策略设计目标分析模块与主参数的关系,提出分离准则和实例设计准则对划分结果进行评估。通过电冰箱产品族的模块划分验证了方法的有效性和可行性。
