AN APPLICATION OF A NON-PARAMETRIC TECHNIQUE FOR RELIABILITY COMPARISONS

Abstract

The basic configuration of the subsystem, involving partial sequential and parallel redundancy, is described and certain special problemsARISING FROM THE INCREASING HAZARD RATE (IHR) of one of the blocks are indica ed. Two alternative maintenance procedures are considered; one in which a repair action is initiated when a redundant block fails, the other in which failures in the redundant blocks are repaired at scheduled times and preventative maintenance is performed on the IHR block. Models for predicting the mean time between failures (MTBF) of the subsystem for each of these alternates are derived. From these models the relationship between the subsystem MTBF and the failure distribution of the IHR block is determined. A non-parametric method for predicting certain limiting characteristics of the IHR failure distribution on the basis of a small sample censored test is discussed and then applied to predict which of the alternative maintenance procedures can be expected to give the greatest subsystem MTBF.
