Abstract
A stochastic model for a computer system is developed by providing hardware redundancy in cold standby. The hardware and software are considered as the two main components of the system having operative and complete failure modes. A single service facility is used to repair the hardware component and also to upgrade the software. The service facility is subjected to failure while repairing the hardware. Treatment is given to the failed service facility so that it can resume the assigned repair activities with full efficiency. The up-gradation of the software is done either at its outdated features or when it fails to follow the instructions properly in order to complete the assigned jobs. The failure times of the components and service facility follow negative exponential distribution while the distributions of hardware repair, software up-gradation and treatment time of the service facility are taken as arbitrary with different probability functions. The expressions for some reliability measures are derived in steady state by using semi-Markov process and regenerative point techniques. The graphical study of these measures has also been made for arbitrary values of the parameters.
