【摘要】：商用飞机的设备选型是一项综合技术性和经济性等多重复杂因素的工作,是一个复杂的多目标决策问题。对于飞机制造商而言,应合理地设置选项,开发出适应客户要求的产品,为提高市场占有率打好基础;对于航空公司客户,应对设备选型进行科学合理的决策,以使购置的飞机适应市场需求,在保证安全性的基础上实现最佳的经济性。研究商用飞机设备选项的评价方法,无论对于民机制造商抑或航空公司客户都是非常必要的。本文在分析常见评价方法优缺点的基础上,对飞机设备选项中必选设备的多选问题和可选设备的最优选择问题进行了评价分析,主要开展了以下研究:(1)以制造商的视角来考虑设备类的初选,以通用性、可靠性、性能、经济性为一级指标,建立了面向制造商的设备选项评估模型。采用多目标规划的方法对面向制造商的设备选项模型进行求解;(2)从客户的角度出发,在初选的基础上对设备类进行精选。以可靠性、维修性、性能和经济性为一级指标,建立面向客户的设备选项评估模型。先后采用层次加权法对设备类选项进行评估;运用经济分析法研究了设备选项的投入产出问题;采用直接运行成本分析法进行设备选项的评价。(3)对上述方法进行了实例验证研究。通过飞机防撞设备实例,对建立的一整套指标体系进行了验证。结果表明,基于面向制造商到面向客户的一体化飞机设备选项评估方法合理有效。通过对加装翼尖小翼各类经济指标进行直接成本计算,获得加装所需成本和潜在收益,验证了直接运行成本分析法的合理性和科学性。
[Abstract]:The equipment selection of commercial aircraft is a complex and complex work, such as technology and economy. It is a complex multi-objective decision problem.For aircraft manufacturers, it is necessary to set options reasonably, develop products that meet customer requirements, and lay a good foundation for increasing market share; for airline customers, we should make scientific and reasonable decisions on equipment selection.In order to make the purchased aircraft adapt to the market demand and achieve the best economy on the basis of ensuring safety.It is necessary for both civil aircraft manufacturer and airline customer to study the evaluation method of commercial aircraft equipment options.On the basis of analyzing the advantages and disadvantages of common evaluation methods, this paper evaluates and analyzes the problems of multi-selection of necessary equipment and optimal selection of optional equipment in aircraft equipment options.In this paper, the following research is carried out: (1) to consider the primary selection of equipment from the manufacturer's point of view, a manufacturer oriented equipment option evaluation model is established based on the criteria of generality, reliability, performance and economy.The method of multi-objective programming is used to solve the equipment option model for manufacturers. From the customer's point of view, the equipment class is selected on the basis of primary selection.Based on reliability, maintainability, performance and economy, a customer-oriented evaluation model of equipment options is established.The method of hierarchical weighting is used to evaluate the equipment option, and the input-output problem of the equipment option is studied by using the economic analysis method.The direct operation cost analysis method is used to evaluate the equipment options.An example of aircraft anti-collision equipment is used to verify the established index system.The results show that the evaluation method of aircraft equipment options based on manufacturer-oriented to customer-oriented is reasonable and effective.Through the direct cost calculation of all kinds of economic indexes of wingtip wings, the cost and potential benefits of adding airfoil are obtained, and the reasonableness and scientificity of direct operating cost analysis are verified.
