Reliability Evaluation of Web based Software


P. K. Suri, Bharat Bhushan


Vol. 7  No. 9  pp. 151-156


The IEEE defines reliability as “the ability of a system or component to perform its required function under stated conditions for a specified process time”. To most project & software development managers, reliability is equated to correctness, that is, they look to testing and the number of bugs found & fixed. Web based software consists of finite number of modules called web pages. The control is transferred among the web pages through hyper links according to Markov process [1, 2]. The software fails or reaches its final state successfully and/or moves to another state and finally enters into the terminal state. The reliability of web based software may be defined as the probability of entering of web based software into a terminal state successfully. The present paper attempts to analyze the reliability behavior of web based software system using Markov process. The software simulation technique designed here will act as a tool for the software quality assurance (SQA) team for evaluating the reliability of web based systems. The reliability evaluation acts as indicator of quantum the SQA needed for meeting the project software quality objectives.
