基于可用度的非等检测周期和不完全维修优化
Availability-based maintenance optimization under unequal inspection period and imperfect repair
摘要
Abstract
Taking the multi-component system as research object,a maintenance optimization model based on the unequal inspection period and imperfect repair is established by considering the requirement of expected availability for improving the system's availability.An age reduction factor is used to describe the effect of imperfect repair,and the modelling approach for the unequal inspection period is proposed.Unavailable situations are classified into three kinds of independent cases,and the availability is calculated accordingly.Based on the analysis of the relationship between the unavailable cases and the unequal inspection period,an optimization model under imperfect repair is established to optimize the system's expected availability.A case study of a wind turbine is provided,and three key components,i.e.gearbox,generator and spindle,are considered.The optimization results of the unequal inspection period model and the equal inspection period model are compared.The results show that the unequal inspection period model based on availability can update the maintenance plan so as to optimize maintenance activities and improve the system's availability.关键词
