Abstract : A Mathematical model for a Computer
system is developed by considering the aspects of
priority in repair disciplines, cold standby redundancy
and independent failures of components. There is a
single server who visits the system immediately for
conducting h/w repair and s/w up-gradation. Server
inspects the h/w components at their failure to see the
feasibility of repair. If repair of the h/w components is
not feasible, they are replaced by its identical
components. However, only up-gradation of the s/w is
made by new one at their failure. And, priority for the
s/w Up-gradation in one computer system is given over
inspection and repair of the h/w components in another
computer system. The system works as new after repair
activities. All the failure time distributions are assumed
to be negative exponential while that of inspection,
repair and replacement times are taken as arbitrary with
different probability density functions (pdf). The
expression for some important performance measures
of the system are derived in the steady state using semi-
Markov process and regenerative point technique. The
graphical behavior of MTSF, availability and profit
function has been observed for particular values to
various parameters and costs. The profit of the present
model has also been compared with that of the model
Malik and Anand [2011].
Keywords: Computer System, Hardware Failure and
Priority for the Software Up-gradation, Inspection,
Feasibility of Repair and Statistical Modeling.
