民机直接维修成本系统动力学仿真研究

Research on Simulation Approach Based on System Dynamics for Civil Aircraft's Direct Maintenance Cost

以民用飞机直接维修成本为研究对象,分析了成本产生的因果关系,绘制了存量流量图,建立了存量、流量、辅助变量、常量之间的关联方程以及确定其初始值;在确定模型合理的基础上,分析了模型的计算结果,并通过调整模型的参数来观察模型结果的变化以确定最优策略,为决策者提供决策支持。分析结果表明,仿真方法具有一定的实用性。

This paper first analyzes the causality of the direct maintenance cost＇s generation;then draws the stock and flow diagram, establishes the correlation equation of stock, flow, instrumental variables, con- stants and determines their initial value;on the basis of the model reasonable,analyzes the model＇s calcu- lation results, observes the change optimal strategy, provides decision of the model results by adjusting support for decision- makers. The per＇s simulation method＇s practicality model＇s parameters to determine the analysis results have verified this pa-per＇s simulation method＇s practicality.
