THE APPLICATION OF FUZZY CLUSTER ANALYSIS IN THE EVALUATION OF DURABILITY OF COMPONENTS

Based on the fuzzy partition clustering, an evaluation method of components durability is proposed. According to the principle that the sum of squares of generalized Euclid distance of durability indexes between components and their clustering center should be the least, the durability fuzzy partition matrix is modified by use of iteration until the optimum result is obtained. The method proves to be correct. It avoids the irrationality in the conventional method and can be easily realized by programming.
