Optimising Maintenance Intervals for a Component using a New Hill-Climbing Algorithm

Maintenance reduces the occurrence of failures of a component (or IT product) and also extends its useful life. This way the time to dispose of such a component may be delayed and this reduces the rate at which greenhouse gases enter into the food chain and the atmosphere. It will be helpful to produce set of maintenance intervals for such component at which its extended useful life and cost are most improved. This set will consist of trade-offs between extended life and cost and is known as optimal set. This paper builds on earlier work to define the optimisation of the maintenance intervals of a given component with respect to its extended useful life and cost. The paper also establishes and uses a new approach of hillclimbing search algorithm.
