基于系统工程理论的民用飞机成本问题研究

The study of civil aircraft cost based on the system engineering theory

针对民机成本问题开展分析,其重要性在民用航空市场上日益凸显。由于成本的范畴广泛,关系复杂,采用系统工程的分析方法对其进行研究,捕获相关利益攸关方的需求,建立民机成本的功能模型和功能分解树,并针对"降低直接运营成本(Direct Operation Cost,以下简称DOC)"这一子功能开展具体的分析。同时,确定直接运营成本的飞机级设计需求,并将其分解至系统层级,并针对"降低燃油成本"和"降低直接维修成本"这两个具体需求开展设计、验证和优化流程与方法的探讨,为民用飞机的成本研究问题提供参考。

The importance of the cost issue in aviation market is growing day by day.Thus,the cost is analyzed adopting the system engineering analysis methods due to its complexity.Different needs from different stakeholders are captured to form the functional model and decomposition tree of civil aircraft cost.In addition,the specific analysis of the sub-function"decrease the Direct Operation Cost(DOC)"is carried out.The DOC design requirements in aircraft level are obtained and divided into system level.Design,verification and optimization processes and methods are derived for two concrete requirements,"decrease fuel cost"and"decrease direct maintenance cost".The study would provide useful reference for the research of civil aircraft cost issue.
