Reliability Analysis Of Multi State Coherent Systems Atefe Gheisari a gheisary@math iut ac ir 2019 Department of Mathematical Sciences Isfahan University of Technology Isfahan 84156 8311 IranSupervisor Dr Sareh Goli s goli@cc iut ac irAdvisor Dr Maryam Kelkinnama m kelkinnama@kashanu ac ir2010 MSC 90B25 Keywords Reliability Multi state system Mean residual lifetime Faliure tree Markove process AbstractRecently interest has grown in the study of multi state systems because some practical systems and components haveseveral different performance levels In addition each component may have more than two different failure modeswhich each mode has a different effect on the system level performance Thus such systems should be investigatedas multi state systems The multi state system is a system with the property that the system and each componenthave i i 0 1 M possible states where 0 is the complete failure state and m is the perfect functioning state Inrecent years there has been some interest in the multi state k outof n systems and its properties The system is said tohave multi state k out of n structure if the system is in state j or above if there exists an integer value l j l M such that at least kl components are in state l or above Multistate k out of n systems have many applications fordescribing engineering systems such as oil supply system manufacturing system and lighting system El Neweihi et al 1978 introduced the first definition of multi state k out of n systems According to this definition a system hasa performance level in state j or above if at least k components are in state j or above A generalized multi state k out of n G system defined by Huang et al 2000 which in this system k can have different values for different systemstate levels Zuo and Tian 2006 obtained algorithms for reliability evaluation of such system Afterwards Tian et al 2009 studied a new multi state k out of n system and made a algorithm for its reliability evaluation Kolowrockiand Soszyska 2006 Kolowrocki and Kwiatuszewska Sarnecka 2008 and Eryilmaz 2010 considered a multi state k out of n system with M 1 possible states then the lifetime of the system in state j or above is actually the
