Abstract: The statistical product control, also termed as, acceptance sampling, extensively used in enterprises to reach a decision on ruling of lots of manufactured products, is a definite plan that states the sampling rules to be used and the standards for acceptance or dismissal of lots submitted for inspection. In acceptance sampling, the largely used practice to minimize the testing time and cost of inspection of manufactured units is the variable sampling inspection plan, in which the sentencing of a lot of individual items is based on metrical data. One of the special purpose sampling plans, multiple deferred state sampling plan for attributes reviews the quality of current lot as well as forthcoming lots for settlement of a lot. This paper proposes a technique for designing a multiple deferred state sampling plan for variables with the quality characteristics of product following normal distribution. The optimized parameters of the proposed plan are assessed by utilizing two points on the operating characteristic (OC) curve for specific requirement to ensure upon the producer and consumer conservation, when the standard deviation is known and unknown.
