Maintenance decisions considering on minor repair time differences in a hybrid system
To improve system operation rate while reducing maintenance cost,considering the impact of the difference in equipment maintenance time,a two-objective optimization maintenance decision-making model for the hybrid sys-tem was established.Based on the equipment failure rate decay curve,considering each device in the compound sys-tems of minor repair time,preventive maintenance time and system reliability,the system run rate and maintenance cost model was constructed,which was taken as the goal to construct hybrid system maintenance decision model un-der the threshold of system reliability and equipment failure rate.The case results showed that compared with the maintenance decisions made by assuming the same time of minor repair of different equipment in the system and the same maintenance time of different equipment in the existing study,the maintenance decision made by considering the difference between the repair time of different equipment in the system and the time of preventive maintenance was more realistic,the result was more real and the effect was better.
