rejuvenation model based on periodical inspection policy is set up. Firstly, by analyzing runtime
state and failure feature of software system, the functions of system unavailability and cost rate
are given and optimal system inspection interval and software rejuvenation interval are selected
via minimizing system unavailability and cost rate. Then boundary conditions of cost rate and
optimal inspection interval are deduced. Finally, quantitative analysis and numeric experiment
result show that selecting optimal inspection interval and software rejuvenation interval can
greatly reduce system cost and improve system availability and reliability. In addition, the
numeric experiment result further validate that the software rejuvenation model with periodical
inspection policy has higher system availability than the general software rejuvenation model in
the case of the failure rate following Weibull and exponential distribution. © 2013 Asian Network
