基于群体决策的软件构件质量评价模型研究

Research on evaluation model of software component quality based on group decision-making

为了简化层次分析法(AHP)在构件质量评价过程中的步骤,同时降低评价过程当中的主观性,建立了一种基于群体决策的软件构件质量评价模型。通过采用改进的AHP,在保证单个判断矩阵满足一致性的前提下,求出指标权重,同时用每个专家赋予不同的权重对指标进行评价。将指标的权重和专家权重进行线性加权,在专家权重相对确定的情况下,采用基于群体决策的策略对构件质量进行综合评价。实验结果表明,该方法较大程度上减少了建立判断矩阵时的主观性,使计算过程更具客观,最大程度地接近了计算结果的真实性。

To simplify the steps of the analytic hierarchy process （AHP） in the software component quality evaluation procedure and reduce the subjectivity in the evaluation. Based on group decision-making, a evaluation model of software component quality is proposed. By the premise of guarantee of single judgment matrix satisfying consistency, the index weight is calculated by the way of the improved AHP. Meanwhile, every expert＇ s relative weight is determined in-group decisions. And then a synthesis evaluation method of index weight based on expert＇ s relative weight is presented by using weighted linear. In this way, to a much greater extent, the subjectivity of establishing the judgment matrix is reduced, and the calculation is more objective. Thereby the result of calculation is more authenticity.
