Method of Testability Allocation Based on Triangular Fuzzy Numbers
Tang Wencha · Ceshi jishu xuebao · 2014
Considering multiple factors that affect the distribution of the test,experts are needed through pairwise comparison to determine the relative importance of the factors. However,due to the people's judgment of fuzziness and uncertainty,judgment in the structural comparison judgment matrix is often not given a value determined. To this problem,proposed a testability allocation method based on triangular fuzzy numbers. The method using triangular numbers to represent the numerical range of expert judgment,considering the fuzzy judgment,change inelastic hard index into fuzzy soft index,establish a structural model based on triangular fuzzy numbers,combined with the analytic hierarchy process( APH) to determine the index weight method,distribution of test indexes obtained by gaining weight. Finally,an example application study of this paper,the application results proved the feasibility of this method.
