GENERALIZED CSP-(C1, C2) SAMPLING PLAN FOR CONTINUOUS PRODUCTION PROCESSES

Abstract

In this paper, a new continuous sampling plan is introduced whose sampling inspection phase is characterized by the maximum allowable number of nonconforming units c1 and c2 and the sampling rates f1 and f2 and is designated as CSP-(C1, C2). A Markov chain model for the proposed plan is formulated and certain common measures of performance are derived. The continuous sampling plan of type CSP-C developed by Govindaraju and Kandasamy12 is a special case of this new sampling plan. Moreover, Dodge's continuous sampling plan (CSP-1) also becomes a special case of proposed plan. The advantage of the proposed plan is to achieve a reduction in the average fraction inspected at good quality levels compared with the CSP-1 and other continuous sampling plans.
