Civil Aviation Maintenance Cost Analysis And Evaluation

This research is the scientific research project done by Civil Aviation College of NUAA cooperating with one civil aviation manufacturer but deeper than it. It is composed of the four parts following:The analysis and evaluation of maintenance cost is of great significance for aircraft manufacturers and airlines both. The output of this research can help the manufacturers to optimize their design, manage and control their suppliers and finally reduce the total life cycle maintenance cost during the period of designing the aircraft. Meanwhile it can help the manufacturers to do their market-exploit. To analyze and evaluate the maintenance cost during the period of operating the aircraft can help the airlines to make their maintenance funds arranged and used reasonable, and optimize their maintenance planning by given scientific data support. Meanwhile it help the decision-maker to do a reasonable decision in exploiting the lines, lines arranging and the number and modal of the aircraft planned to buy as well.1. establish a database of civil aviation cost;2. research the way how to confirm, assign and predict the maintenance cost especially the direct maintenance cost(DMC) during the phase of the design of civil aircraft. And the author brought out the DMC analysis flow, work procedure for calculating DMC, assign and prediction for the system's DMC.3. research the way how to analyze and evaluate the maintenance cost especially the airframe maintenance cost during the phase of operation of civil aircraft. And the author brought out the maintenance cost prediction method for the single airframe maintenance event based on the airlines maintenance program and the prediction method for the annual maintenance cost based on the grey theory.4. establish a software system of the analysis and evaluation of the civil aircraft maintenance cost.
