Optimisation of test times of electronic equipment by the application of statistical test procedures

Abstract

This project report investigates the feasibility of applying statistical test procedures ( or sampling inspection ) to reduce the time spent on inspecting electronic modules produced on the various production lines of Telephone Manufacturers ( TM ). The effect of these procedures on such factors as the average outgoing quality and the production yield, is examined. h-. Two inspection situations exist at TM but no information concerning the production process ( distribution of defective products ) is available, this data must therefore be simulated. A number of sampling plans are chosen for evaluation. The relative performance of each of these sampling plans is then assessed using the simulated production process data. The sampling plan that produces the best results, is selected for implementation.
