STOCHASTIC MODELING OF SINGLE UNIT SYSTEMS WITH DELIBERATED FAILURES SUBJECT TO WARRANTY

Abstract

The prominent objective of present study is to analyse the impact of warranty and deliberated failures on single unit systems.
A novel stochastic model is developed using regenerative point technique (RPT) and semi-Markovian approach (SMA) for a
single unit system. The system suffers due to two types of failures with warranty period namely normal failure and deliberated
failure. Warranty period for the system is prespecified and after that no provision of extended warranty is made. All kinds of
failure rates, repair rates are Lindley distributed while warranty period follows exponential distribution. Various measures of
system effectiveness derived. The numerical values of these measures are derived for a particular case with respect to failure
and repair rates.
