A novel routine outage maintenance strategy is proposed. The optimization model for routine outage maintenance is established

minimizing the objectives of the cost of maintenance

the loss of gain from power selling

and the loss of over-reparation. The practicality of the new strategy is improved

since the data used in the mathematical model is supported by condition-based maintenance technology. The new strategy is evaluated by utilizing the probabilistic production simulation technique

with a comparison made with the time-based maintenance (TBM) strategy. Test results show that

in terms of both the economic index and reliability index

the new strategy is superior to the TBM strategy.
