Abstract

This research work presents a new approach to prioritize distribution maintenance activities based on system reliability and cost-effectiveness. The objective of this approach is to minimize the weighted average system reliability index (WASRI) by ranking maintenance tasks based on their marginal benefit-to-cost ratios, where the benefit is defined as improvement in WASRI. Estimations of WASRI improvement are obtained by utilizing the linear relationship between the benefit obtained from a maintenance task and the change of failure rate of the maintained component.
