Abstract: Under the condition of serial system without intermediate buffers,perfect and imperfect preventive maintenance ways existed in system by assuming machines were subjected to Operation Dependent Failures (ODF),which were limited in maintenance resource.On this basis,an integrated production lot and maintenance planning model was presented by considering stockout and inventory cost.An integrated mathematical model of multi-machine serial system was established,and a multi-stage decision solving method was proposed for the complex non-linear characteristic of this model.For analyzing the problem of model's large decision space,the genetic algorithm was used to search the maintenance planning group.By comparing with the enumeration method and the simulated annealing algorithm,the effectiveness of the model and the superiority of the proposed algorithm were illustrated with practical experiments.

Key words: production lot planning, maintenance planning, joint optimization, multi-machine serial system
