Sequential Sampling Plan by Variable with Fuzzy Parameters

In this present paper we have proposed a method for designing sequential sampling plans (SSP) by variable when the acceptable quality levels (AQL) and the rejectable quality levels (RQL) are fuzzy number. We are calculated decision criteria in the fuzzy SSP by variable. This plan is well defined since if two quality levels are crisp, it changes to classical plan by variable. For such a plan, a particular table of rejection and acceptance is calculated and compared with the classical one.
