A Method Based On Fuzzy Evaluation Model Of Layered Component Testability Evaluation

With the rapid development of computer software technology, software products have been applied to all areas of society, today's software has gradually become a collection of components assembled.So that the quality of each component directly affects the overall quality of the software. Therefore, in the beginning of the test, evaluation component testability of components is very important. How to quickly and accurately obtain the evaluation results can be tested components has become an urgent problem.In this paper, the testability of components and the existing evaluation model, a hierarchical model based on fuzzy evaluation component testability evaluation methods, mainly for the following aspects:1 According to the definition of the testability of components and related research results, this paper defines testability evaluation component set, and its stratified.2 Fuzzy comprehensive evaluation method, this paper proposes a hierarchical model based on fuzzy evaluation component testability evaluation methods, the main job of the following areas:(1) For component testability features, the definition of component testability evaluation set.(2) Because the testability of component indicators do not belong to the better, so the indicators proposed algorithm IPA results of different measurement standardization.(3) According to the fuzzy comprehensive evaluation method, this paper proposed AHP, SCTFCE and MCTFCE three algorithm components for test to make a more objective assessment.(4) In order to improve the adaptability of this method, the weight update algorithm is proposed WUA.3 Simulation results demonstrate that the proposed hierarchical model based on fuzzy assessment evaluation component to test the feasibility and effectiveness.
