In this paper, we consider the problem of determining optimal operating conditions for a data processing system. The system is burned-in for a fixed burn-in time before it is put into field operation and, in field operation, it has a work size and follows an age-replacement policy. Assuming that the underlying lifetime distribution of the system has a bathtub-shaped failure rate function, the properties of optimal burn-in time, optimal work size and optimal age-replacement policy will be derived. It can be seen that this model is a generalization of those considered in the previous works, and it yields better optimal operating conditions. This paper presents an analytical method for three-dimensional optimization problem.
