Abstract

This paper investigates the reliability characteristics of a system based on the concept of a university web server. Whenever a browser brow a request different types of error can occur due to which system may suffer from partial to complete failure. Different types of repair as per requirements, including waiting have been incorporated while modeling this real life system. It is interesting to mention here that waiting has been taken as a type of repair when web server is busy. With the applications of Laplace transforms and supplementary variable technique different reliability measures like availability, reliability, M.T.T.F. and effective cost analysis have been evaluated. Some particular cases have been taken at last to highlight the results.
