The invention relates to a power distribution network maintenance vehicle scheduling method which comprises the steps of obtaining vehicle information of each maintenance center and service place information needing to be maintained; substituting the vehicle information of each maintenance center and the service place information to be maintained into a preset operation cost model, and solving byadopting a genetic algorithm to obtain a vehicle scheduling scheme; wherein the operation cost model is constructed by taking operation cost minimization as a target and combining boundary constraintconditions; wherein the services needing to be overhauled comprise planned overhaul, fault first-aid repair and temporary overhaul. The power distribution network electric power fault maintenance service level is improved completely, and the asset management level is improved lean.
