A MATHEMATICAL MODEL TO PREDICT PERFORMANCE RELIABILITY OF A MANUFACTURED COMPONENT WITH MULTIPLE CRITICAL CHARACTERISTICS BY NONDESTRUCTIVE TESTING,

Abstract

A mathematical model was developed for the estimation of the reliability of delivered items. The model is based on a series of assumptions about probabilities in manufacture and quality control. Quality control inspection is assumed to be of a nondestructive type. The mathematical model also indicates the sensitivity of the reliability estimate with respect to changes of the probabilities in manufacture and quality control, and an optimization procedure for a reliability increase with respect to costs is outlined. Some considerations for establishing a confidence level for the reliability estimations are added. (Author)
