Abstract:
1. A non-transitory computer-readable medium storing computer-executable instructions that when executed by a computer cause the computer to perform a method, the method comprising: monitoring a prognostic parameter of a computing system; mapping respective maintenance costs of the computing system to respective prognostic parameter values such that the maintenance cost mapped to a given value is an accumulation of maintenance costs while the prognostic parameter is at the given value; partitioning values of the prognostic parameter into two or more partitions based on the maintenance cost, wherein each partition corresponds to a computing system operating state; assigning the maintenance cost for the values in a partition to an operating state that corresponds to the partition; and selecting a preventive maintenance schedule that minimizes a system cost function that calculates an expected maintenance cost when preventive maintenance is performed in the operating states according to a given preventive maintenance schedule.
