Abstract

Abstract

Based on the modeling thought of modern scheduling theory, the requirement property for aeroengines and the turnover property of aeroengine maintenance were analyzed, the concept of work note was introduced, a scheduling model of aeroengines under condition-based maintenance strategy was established, an online longest processing time (LPT) rule algorithm was improved for solving the model, and the used data of CF6 aeroengines were studied. It is pointed that aimed at aeroengine, on-wing time is longer, maintenance time is lower, guarantee rate is higher, and rental loss cost is lower when LPT rule is compared with traditional first come first serve (FCFS) rule. Analysis result indicates that LPT rule is better than FCFS rule, and the model is feasible.
