A Special Bounded Sequential Procedure.
Abstract
The concept of item by item sequential sampling has been developed from the Wald sequential probability ratio (SPR) test. The SPR plan for one-sided variables inspection is characterized by two parallel lines on a plot of the cumulative sum of observations T(n) versus accumulated sample size n. The operation of the plan is described by analyzing the sequence T(n). The number of observations, n, required for defining a course of action is a random variable, often characterized by large values of n before a decision is made. Truncation rules are required to prevent unacceptable sample sizes even though convergence is guaranteed. This truncation increases the associated producer's and consumer's risk. Herein a sequential non-probability ratio (SNPR) plan is examined which is characterized by intersecting lines and thus an implicit truncation property. A heuristic algorithm to define the parameters of the plan is introduced. The algorithm produces an SNPR plan which provides the same levels of protection as the non-truncated SPR plan.
