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

摘要

This project report investigates the feasibility of applying statisticaludtest procedures ( or sampling inspection ) to reduce the time spent onudinspecting electronic modules produced on the various production linesudof Telephone Manufacturers ( TM ). The effect of these procedures on suchudfactors as the average outgoing quality and the production yield, is examined.udh-.udTwo inspection situations exist at TM but no information concerning theudproduction process ( distribution of defective products ) is available,udthis data must therefore be simulated.udA number of sampling plans are chosen for evaluation. The relative performanceudof each of these sampling plans is then assessed using the simulatedudproduction process data. The sampling plan that produces the bestudresults, is selected for implementation.
