中文摘要：

对产品开发过程中用户需求的获取过程进行研究,找到有效避免用户需求调查过程中的信息遗漏问题的方法.利用可拓学中的事元理论,从用户需求的根源“需要”出发,对产品开发的前端过程进行形式化研究.得出用户需要的获取方法及其事元模型的建立、用户需要的重要度分析方法和计算模型、用户需要模型映射成产品功能模型的方法等.通过对用户需要与产品功能的形式化研究能够很好地解决在产品开发过程中存在的信息遗漏问题,将有助于产品开发团队从用户需要出发,研发出更能满足用户需要的新产品.

英文摘要：

A study is conducted into the process of getting customer demands during the process of product design and development finding the way of avoiding the missing information during investigating customer demands.Based on the theory of affair-element in Extenics,a formal research is made on the front-end process of product development from user"needs",that is,the sources of the user demands.The methods of acquiring user needs and setting up the affair-element models of user needs,the importance degree analysis methods and the calculation model of user needs,the method that user need models to map into the product function models,and so on.Through a formal research of user needs and products'functions,a good solution can be derived to the problem for the product development of information on the first floor,which will contribute to the product development team in developing new products meeting user demands.
