%0 Journal Article %T Evaluation of reliability characteristics of two dissimilar network flow systems %A Ibrahim Yusuf %A Bashir Yusuf %J Applied Mathematical Sciences %D 2013 %I %X This paper presents a study on reliability characteristics of two dissimilar systems.System I consist of two paths while system II consist of three paths. A signal flowfrom the source to the terminal through the paths. Failure times and service times ofeach system are assumed to be exponentially distributed. The failure and repair timesassumed exponentially distributed. Using KolmogorovĄ¯s forward equations method,derivations for availability, busy period and profit function are presented in thispaper. Also numerical illustrations for the two systems are presented. Comparisonsare made based on assumed numerical values for the two systems. %K Redundant system %K reliability characteristic %K Availability %U http://www.m-hikari.com/ams/ams-2013/ams-37-40-2013/yusufAMS37-40-2013.pdf
