OPTIMALITY ISSUES IN A SERIES SYSTEM FROM MANUFACTURER’S PERSPECTIVE CONSIDERING BURN-IN AND WARRANTY PERIODS

Abstract

Reliability engineers generally have to deal with systems that consist of some components in series and others inparallel. Reliability of a series system can be calculated by multiplying the reliability of individual elements in that system.Failure rate of many deteriorating systems shows a bathtub shape curve. The aim of this paper is to find the average totalcost of a series system, from a manufacturer’s point of view, during the first two phases of its life; considering optimalityissues for burn-in and warranty periods. Numerical illustration is provided to show the applicability of the model

Keywords

• Series System, deteriorating system, renewing warranty, burn-in, optimization
