摘要
在对现有的软件产品质量度量方法进行分析的基础上,提出了一种基于粗糙集的属性权重分配方法通过已知数据寻找出对总体用户满意度影响不同的各属性权重因子,发现影响产品质量的关键因素,以揭示质量改进与用户满意度之间的内在互动关系.同时把单层次的知识细化成多层次知识,有助于提高权重设置的精确度,并且结合专家意见更合理的设置权重,弥补了现有方法的不足.
Researching the theory of evaluating index of user satisfaction degree, this paper builds a model and proposes a method to determine objective weights of software products quality based on rough sets. The model and method reflects an internal relationship between quality improvement and user satisfaction degree through external data which can find out the key factors affecting software products quality. Also, subdividing information of monolayer into that of multilayer and combining objective weights and subjective weights given by experts, the model and method improves the accuracy of weights and remedies the inadequacy of existin methods.
