Sažetak
A mathematical model for optimising preventive maintenance of aircraft jet engine was developed by dynamic programming. Replacement planning for jet engine modules is regarded as a multistage decision process, while optimum module replacement is considered as a problem of equipment replacement. The goal of the optimal replacement policy of jet engine modules is a defined series of decisions resulting in minimum maintenance costs. The model was programmed in C++ programming language and tested by using CFM56 jet engine data. The optimum maintenance strategy costs were compared to costs of simpler experience-based maintenance strategies. The results of the comparison justify further development and usage of the model in order to achieve significant cost reduction for airline carriers.
