A computation scheme based directly on the dynamic programming formulation is proposed, a time-sharing computer program is discussed, and the results of an example problem are presented.Abstract:
A method for determining where to locate the inspection stations in a multistage production process with imperfect inspection is presented. Dynamic programming is used to establish that the optimal expected total cost function at every stage is piecewise linear and concave. While the optimal policy at every stage usually consists of one “inspect” region and one “do not inspect” region, this policy structure is found not to hold in general. A computation scheme based directly on the dynamic programming formulation is proposed, a time-sharing computer program is discussed, and the results of an example problem are presented.read more

Process and Product Improvement in Manufacturing Systems with Correlated Stages
TL;DR: A procedure for measuring the effect of each stage's performance on the output quality of subsequent stages including the quality of the signal product, and identifying stages in a manufacturing system where management should concentrate investments in process quality improvement is offered and empirically validates.

Allocation of Screening Inspection Effort---A Dynamic-Programming Approach
TL;DR: In this paper, a general screening inspection program is developed in which inspection levels and the locations of inspection points are treated as variables, and it is shown that the function representing the total of inspection and scrap costs will be minimized by an extreme point solution, thus the minimum-cost inspection program will lie in a relatively restricted subset of all possible allocations.

The Analysis of a Simple Class of Multistage Inspection Plans
TL;DR: Under certain conditions an optimal inspection plan has the property that at every stage either the whole batch is inspected or no inspection is performed, and a very simple dynamic program can be solved to find the optimal plan.

Optimal Screening Plans for Nonserial Production Systems
TL;DR: In this article, the authors defined and evaluated quality control screening programs for the general n-stage nonserial production process and developed a total expected cost criterion, developed as a function of the screening applied at each inspection station, embracing the various costs of inspection, defect repair and defects passing through the process undetected.
