A Study for Airliner Maintenance Cost Optimization

Reducing the direct maintenance cost(DMC) of airliner in the preliminary design by strengthening the reliability design and maintainability design can effectively improve the economics of airliner.In the paper,we used airliner maintenance cost model based on reliability and maintainability design parameters,to collaborative optimize the reliability and maintainability design parameters by collaborative optimization method,for seeking the satisfaction design parameters that can reduce maintenance costs.Maintenance costs design parameters optimized which gave the general ideas of collative optimization for airliner landing gear maintenance cost optimization,all of which laid the foundation for solving airliner system optimization.DMC of airliner landing gear example solves optimization problems of airliner DMC effectiveness.
