Multi-objective decision-making model for distribution system condition-based maintenance

This paper proposes a multi-objective maintenance decision-making model based on Dempster-Shafer (D-S) evidence theory to determine the optimal maintenance scheme from the alternative schemes. This model selects the change of distribution system reliability after maintenance, load loss and maintenance cost as decision-making indexes. And decision-maker's preference of three indexes is also taken into consideration to meet the requirements of different maintenance circumstance.
