- Abstract
Imperfect maintenance policy is always required and carried out on the equipment parts under limited maintenance resources. The maintenance strategy optimization of the imperfect maintenance level for each equipment part becomes difficult for large parts number or high imperfect maintenance levels. To solve the imperfect maintenance strategy optimization problem of equipment with multiple parts and maintenance levels, a repeated cooperative game theory based optimization algorithm was proposed in this research. Considering the imperfect maintenance level of each equipment part as the optimization variable and maintenance cost minimization as the optimization objective, a mathematical model of imperfect maintenance of equipment with multiple parts connected in series was fabricated under the constraints of limited maintenance time and minimal required reliability. Further, considering the administrators corresponding to each equipment part as the game players, the equipment imperfect maintenance model was mapped into a cooperative game scenario. Via constructing the strategy space, setting the payoff in each round of the cooperative game, the updated maintenance plan in each round will move towards the global optimum via repeated game. Moreover, the performance of the proposed method was tested via case and parameter studies, and compared with traditional optimization methods including genetic algorithm method. The analysis results show that the proposed cooperative game algorithm provides overall more accurate optimization results, and enhances the optimization efficiency. The research could provide more practical guidelines for imperfect maintenance strategy optimization of equipment in engineering applications.
