Abstract:

Consider various host systems that consist of both hardware and software. There is an IT center which governs the maintenance activities of all of those host systems. The center's major concern is deciding the proper level of repair capacity for various kinds of failures due to hardware, software, and operator related problems where corresponding failure and repair times may exhibit fairly large variations. In this paper, we use Monte Carlo simulation in order to decide the optimal repair capacity when both failures and repair times of individual host systems exhibit long-range dependent property. In terms of utilization rate, average and maximum waiting times, we suggest the optimal capacity of maintenance. Various sensitivity analyses follow.
