Stochastic behaviour of various specific computer reliability models
Abstract This paper introduced two stochastic models related to various computer configurations, an expert system and a UNIX environment performance system. These types of system are useful in many areas such as diagnosis, monitoring, debugging, instruction, control, prediction, interpretation, designing and planning. It is the best tool for good decision making. In these systems, input information and data enter into control mechanism and, after that, processing in various facilities. After processing the data, conclusions or recommendations can be achieved in the form of output data. A practical problem also arises in this process, i.e., rebooting. Preventive maintenance (PM) is required to increase the working capacity of such a computer. Several cost effective reliability measures have been obtained using the Markov renewal process and graphical representations are also provided for further study.
