基于直觉模糊集的构件质量评价模型研究

Research on evaluation model of component quality based on intuitionistic fuzzy sets

为了客观地反映构件指标的模糊性并增强决策的柔性,建立了一种基于直觉模糊集的构件质量评价模型。首先,在ISO/IEC 9126软件质量度量模型基础上,通过增加、删除质量特性和质量子特性,建立了构件质量评价指标体系;其次,将直觉模糊集引入构件质量评价模型并给出了构件质量评价的具体步骤;最后,利用基于直觉模糊集的评价模型给出了待评价构件的优劣排序。实例验证了该方法的合理性与有效性,为构件评价工作提供一定参考。

An evaluation model of component quality is presented in this paper. The proposed model can reflect the influence of fuzzy factors and enhance the decision flexibility. First, based on ISO/IEC 9126 software quality model, a component quality index system is established by adding or dislodging some quality characteristic and sub-characteristics. Then, intuitionistic fuzz- y set is introduced into the evaluation model, and the relevant steps on component quality evaluation are proposed. Finally, the evaluation model is able to rank the components. The experimental results and the analysis show the feasible of the approach. It can provide feasible reference for component evaluation.
