Abstract

In the areas of reliability analysis, the applications of life testing play a great important role. Under the deterministic circumstances, production reliability acceptance test (PRAT) for reliability sequential-sampling test (RSST) possesses high reliability and economic values in various fields. However, the past literatures showed that some of these uncertainties during the sampling inspection originate from trend, season, cyclic, or random variations; others come from improper operations. Hence, under these factors effect, the RSST may generate a vague value. In order to deal with uncertainty happened; this paper applies the triangular fuzzy number (TFN) are used to express the fuzzy phenomenon of the reliability sampling inspection's parameters. Also, both the centroid and the signed distance approaches are used for defuzzification. To compare these estimates of the reliability sequential-sampling plan in the fuzzy sense, the better defuzzification method is generated.
