Joint optimization of production and maintenance for system considering quality losses under imperfect maintenance
Aiming at the problem of quality losses in a serial production system considering equipment deterioration,Wiener process was used to model equipment deterioration,the strategy of imperfect maintenance and replacement based on real-time product quality information was proposed by considering the comprehensive influence of equip-ment imperfect maintenance on the residual degradation level and residual degradation rate,which was optimized in conjunction with the production plan,and the mathematical model of minimizing the total cost was established.The Monte Carlo simulation was used to sample the total cost and a flower pollination algorithm with optimized conver-sion probability was used to solve the model.Numerical experiments showed that the condition-based maintenance strategy using real-time quality information had a lower total cost than other three types of comparison strategies,with an average optimization ratio of 9.61％under high production load system and 10.71％under low production load system.
