The needs of users are usually vague and uncertain for component-based software system development. Proposed a model of a non-linear fuzzy quality function deployment(NF-QFD)of the component selection.The model consider the maximizing of the cohesion and minimizing of the coupling of software component models,and at the same time,take into account maximizing the user requirements.The model can solve the optimization problem of the component selection in the software development,and provide more decision-making support for designers.%在利用构件进行软件开发时，用户的需求通常是模糊和不确定的。提出了基于非线性模糊质量功能展开（NF-QFD）的构件选择模型。该模型在考虑构件之间高内聚、低耦合的同时还兼顾用户需求最大化，通过该模型可以解决软件系统开发时构件选择的优化问题，为设计人员提供更多的决策支持。
