Abstract

Three-level Skip-lot sampling plan split by two stages (Split2-SkSP0 is proposed by modifying multi-level skip-lot sampling plan proposed by Choi(1993), which has normal and terrace inspections on the first and the second stages, respectively. The plan is designed to work more higher level inspections when the quality of the submitted products are good, otherwise, return to the normal or the terrace inspection as fast as possible. Also, the formula of the operating characteristic function for the split skip-lot sampling plan is derived using the Markov chain approach. Also, operating characteristic properties of the proposed plans are studied and graphically compared with those of the multi-level skip-lot sampling plans.

다단계 스킵-로트 샘플링 검사계획(Choi, 1993)을 수정하여, 1단에 정규검사 2단에 단지(段地, terrace)검사를 둔 2단으로 분할된 스킵-로트 샘플링 검사계획을 설계하였다 스킵-로트 샘플링 검사계획은 제품의 품질이 우수할 경우에는 더 높은 단계의 검사를 수행하고, 그렇지 않을 경우에는 곧 바로 정규검사 또는 단지검사로 되돌아가도록 되어 있다. 마코프 연쇄를 이용하여 분할된 3단계의 샘플링 검사계획의 검사특성곡선을 도출하여 그 성질을 규명하고, Choi의 샘플링 검사계획과도 비교하였다.
