  In this study, we assume a software process model with independent functions as a component. The vaguer and ambiguity aspects of human thinking and reasoning process lead people to utilize fuzzy theories to solve certain problems. The goal of this paper is to employ the method of fuzzy mathematic to classify the components in component library during the process of software evolution. To classify component, the target parameters extracted from components are selected out before the standardization and the clustering is performed after the establishment of fuzzy equivalent matrix. This paper outlines the overall processes of the classification of a component and finally an example is discussed as a case study.

  The Rosenbloom-Tsfasman metric (RT, or ρ, in short) is a non-Hamming metric and is a generalization of the usual Hamming metric, so the study of it is very significant from both a theoretical and a practical viewpoint. In this study, the definition of the exact complete ρ weight enumerator over Mnxs (R) is given, where, R = Fq+uFq+...+ut-1Fq and ut = 0 and a MacWilliams type identity with respect to this RT metric for the weight enumerator of linear codes over Mnxs (R) is proven which generalized previous results. At the end, using the identity, the MacWilliams identity with respect to the Hamming metric for the complete weight enumerator cweC (x0, x1, xu,..., x(q-1)+(q-1)u+...+(q-1)ut-1) of linear codes over finite chain ring R is derived too.
