Research on maintenance manner optimization of airborne product based on RCM

More than 90% of the helicopter attachments repair by way of hard-time maintenance, which brings great inconvenience and huge material consumption to the user. In this paper, the mathematical models are established by analyzing the factors affecting repair decision-making from reliability, maintainability and efficiency perspective and adopting the method of FMEA combined with an improved logic decision graph, which determine the maintenance manner and the maintenance interval under different maintenance modes. By improving the maintenance manner and determining the maintenance interval under different maintenance modes, the goal of this thesis is to effectively change the improper maintenance and salve the problems of high cost and low availability. Then, the optimized maintenance manner, based on the proposed optimization model, effectively determines airborne products maintenance methods and maintenance interval for a type of helicopter, which has shown the validity and applicability of the decision mode and method.
