摘要
We once proposed four metric criteria for the multi-dimensional software trustworthiness such as monotonicity, acceleration, sensitivity and substitutivity, and presented two metric models based on theses criteria. Both the substitutivity among critical attributes are 1 and that among non-critical attributes are either 1 or 0 in our two models. In fact the substitutivity between different critical attributes or that between different non-critical attributes should be different. In order to deal with this problem, in this paper we partition critical attributes into several groups. The substitutivity between attributes within the same group are identical, and the substitutivity between attributes belong to different groups are not the same.
