Calculations of Amounts of Joint Reservev of Airplanes in Civil Aviation Systems

摘要

In this paper, based on the "airplane repairing" model and "airplane purchasing" model, for the N systems of single unit from different airline companies where reserve of airplanes starts at the same time under the same storage conditions that normal probability is not less than P_0 during the designed storage period T_0 , the spare parts number M for N identical systems is derived. According to the same principle, ideas of joint reserve of airplanes have been proposed, and the validity has been checked through the examples of Weibull distribution.
