为了提高软件可信性评估的准确性,提出了一种基于模糊灰色关联分析的软件可信性评估方法,该方法使用梯度模糊数计算各个可信指标的权重。首先计算出软件可信指标的正、负理想值,然后使用灰色关联分析方法计算出可信指标度量值对正、负理想值的灰色关联度,依次计算出软件可信性评估值。其中,通过模糊梯形数对可信评估指标的权重值进行处理。应用结果表明:所提方法对于软件可信性的评估是有效的,结果具有较高的准确性。

In order to improve the accuracy of software trustworthiness evaluation , a method is proposed based on fuzzy grey relational analysis , and the weights of the evaluation indicators for software trustworthiness are calcu-lated by trapezoidal fuzzy number method .First, the positive and negative ideal values of trustworthy indicators are calculated from the positive and negative ideal points .Then, the trustworthiness for software is computed through fuzzy grey relational analysis , and software trustworthiness evaluation values are calculated , especially , the weights of the evaluation indicators for software trustworthiness are calculated through trapezoidal fuzzy num -ber method.Application results show that the proposed method is effective and highly accurate , and does not cause much computational burden .
