Research on distribution equipment condition-based maintenance using drosophila optimization algorithm

In view of the disadvantages of preventive maintenance for power distribution equipment, the power distribution equipment use state maintenance. Firstly the optimization model of preventive maintenance plan based on the minimum cost was set up, because of its disadvantage; add the reliability constraint conditions to establish the improved optimization model. Finally, the improved fruit fly optimization algorithm was use to solve the problem. Examples demonstrate the correctness of the improved model and the validity of the algorithm.
