Research of preventive maintenance task interval optimization model and method of aircraft

Aircraft maintenance order specifies all preventive maintenance tasks involved in aircraft basic level maintenance. During the beginning of aircraft service,the maintenance tasks are intended to be conservative. With the accumulation of aircraft use and maintenance experience,the demand for optimization of maintenance task interval is becoming more and more obvious. Taking the service data as the analysis object and the system reliability as the measurement standard,the optimization analysis method of preventive maintenance task interval is constructed and a realizable mathematical model is formed in this paper. Taking a maintenance task as an example,its service data are analyzed and suggestions on maintenance interval optimization are given. The example has proved the feasibility of the mathematical method and model which can be used as a reference for military aircraft maintenance task interval optimization analysis.
