In this paper we introduce a new sequential sampling plan based on sequential probability ratio test for fuzzy hypotheses testing. In order to deal with uncertainty happened, the triangular fuzzy number (TFN) is used to express the fuzzy phenomenon of the sampling plan’s parameters. In this plan the acceptable quality level (AQL) and the lot tolerance percent defective (LTPD) are TFN. For such ...

This paper presents the procedure for the construction and selection of the mixed sampling plan using MAPD as a quality standard with the TNT(n;c1,c2 ) plan as attribute plan. The plans indexed through MAPD and AQL are constructed and compared for their efficiency. Tables are constructed for easy selection of the plan.

Abstract In conventional sampling plans, the rate of fraction faulty items is supposed and fixed, but in some practical situations, this value not fixed fuzzy. To attain real flexible value, we used transmuted Weibull distribution a fuzzy environment. Fuzzy based on set theory. According to our investigation, acceptance The improvement research evaluate vague portion malfunctioning ( $$\tilde{p...
