Aircraft life cycle cost evaluation method

Abstract

The invention belongs to the field of aircraft life cycle cost evaluation, and particularly relates to an aircraft life cycle cost evaluation method. The method comprises the following steps: performing staged cost evaluation at the initial stage of aircraft development, including scheme argumentation stage evaluation, preliminary design stage evaluation, detailed design stage evaluation, production initial stage evaluation and use guarantee stage evaluation; and performing index cost evaluation in the middle and later periods of aircraft development, wherein the index evaluation comprises complete machine index evaluation and system / component index evaluation. The full-life-cycle cost evaluation method is put forward in the field of aircraft equipment, and the cost of the whole aircraft development process can be evaluated; according to the cost evaluation method, different methods can be used for evaluating the whole life cycle cost of the airplane according to the characteristics of each development stage of the aircraft; a rapid and effective evaluation means is provided for the whole-life-cycle cost design work and the cost examination work of the aircraft, and a decision basis can be provided for the whole-life-cycle cost management and control work of the aircraft.

Description

technical field [0001] The application belongs to the field of aircraft life cycle cost evaluation, and in particular relates to an aircraft life cycle cost evaluation method. Background technique [0002] The excellence of aircraft not only refers to the excellent performance and advanced technology, but also reflects the advantages and disadvantages of the whole life cycle cost. Aircraft life cycle cost evaluation is to conduct research and comparative analysis on the basis of full life cycle cost estimation, and then conduct cost evaluation by analyzing key cost units and influencing factors, cost risk items and risk levels, cost / efficiency / benefit , to provide decision-making basis for controlling and reducing life cycle costs. [0003] At present, the life cycle cost evaluation of many equipment products is self-contained. Due to the differences with foreign systems and the relative weak technical foundation, it is difficult to quickly reach foreign standards. The who...

Problems solved by technology

Due to the differences with foreign systems and the relative weak technical foundation, it is difficult to quickly reach foreign standards, and the whole life cycle cost of aircraft can only be judged from a technical point of view to a certain extent
