Abstract

In this paper, author focus on the profits of a computer system with software redundancy by introducing the concept of hardware preventive maintenance (PM), priority to hardware PM and hardware repair over software up-gradation. The system fails independently from normal mode. All the repair activities such as hardware repair, software up-gradation, hardware preventive maintenance before failure and hardware replacement after maximum repair time are carried out by a single server immediately, if required. All random variables are statistically independent. The negative exponential distribution is taken for the failure time of the component while the distributions of repair time, up-gradation time, preventive maintenance and replacement time are assumed arbitrary with different probability density functions. Semi-Markov process and regenerative point technique are used for obtaining the values of various parameters. The behaviour of profits has been examined.
