Abstract:
What we have today as our integral part of our daily life is networked and distributed system, its application covers from handled device such as cellphone and remote car keys to sophisticated equipment used in aircrafts, power systems, nuclear plants and healthcare system. Considering the critical importance of these system any failures of any of the element/components can significantly affect the performance of component resulting having detrimental or catastrophic impact. One of key component is user who is responsible on operation of the system; failure of user is responsibilities can results into catastrophic impact. This paper discusses the issue of reliability of system particularly mathematical modeling of user reliability on Networked and Distributed systems. To accomplish this we have outlined the background of the study, reliabilities of systems, user models, user reliabilities (user profile) model and provide a proposed mathematical user reliability model and concluded by point out the importance user reliability model.
