Operational availability demonstration of military airplane based on simulation

Jiao Jian Wang Zili(Dept.of System Engineering of Engineering Technology,Beijing University of Aeronautics and Astronautics,Beijing 100083,China)  
Operational availability(A_O) is an important top parameter of military airplane RMS(reliability,maintainability and supportability).In order to obtain reasonable and valid A_O,based on characters of demonstration stage,a simulation model using Monte-Carlo method and queue theory was constructed by integrating the mission requirements,initial operations and support concept of military airplane and RMS data from similar systems.The sample methods of mission start,failure time and repair time were analyzed,and the sample formulas were presented.The model requires military airplane RMS data and operation maintenance scheme as input data,and calculates iteratively a family of relative curves between A_O and RMS parameters.Based on analyzing the curves synthetically,the reasonable results could be obtained.The algorithm processes of reliability simulation and relative formulas were presented,and the method was verified by a case as well.The simulation model has general-duty character and can be used for different parameters demonstration by modifying the statistical formulas.
