Abstract: Existing maintenance models are lacking in relevance due to the neglect of the operating characteristics of these devices during the establishment process.The scheduling of maintain resource should be taken into account when formulating the equipment maintenance plan as the overall optimal management idea being popular.Based on this,it takes the equipment that does not allow downtime during operation as the research target,and establishes the sequence preventive maintenance model by using the relationship between equipment reliability and service age.Secondly,In order to optimize the maintenance plan under the condition that the maintenance resources are fixed,it establishes the maintenance center cost minimization model according to the maintenance plan of the equipment based on the analyzing of cost factors for the maintenance center.Finally,it takes a medical monitor that its failure time subjects to Weibull distribution as an example.The simulation results show that the model can meet the maintenance of the equipment and proves the feasibility of the proposed joint optimization method.

Key words: preventive maintenance, time window, linear approximation, vehicle scheduling
