摘要:

为了定量反映民机“座级”、“设计航程”与直接运行成本之间的内在关联性,利用NASA 97方法为各种样本机型在不同的长短结合的“飞行航距”下生成直接运行成本样本点,确定“型别等级”民机市场直接运行成本与“飞行航距”的函数形式并计算回归系数的估计量,以此分析“座级”、“设计航程”与各个回归系数估计量之间的函数关系,给出“型别等级”民机市场DOC的计算模型函数,通过OLS方法估算模型的回归系数.通过与NASA 97 方法对4种样本机型产生的10个样本点的比较,发现模型计算的最大相对误差为0.086,因此模型可行.

Abstract:

To quantitatively reflect the interrelationship of direct operation cost with seat class and designed range for civil aircraft, this paper first uses the NASA 97 method to generate sample points of direct operating cost for various aircraft types over any mix of flying distance. Then, the functional form between direct operation cost of aircrafttyperank and flying distance is determined and the regression coefficient estimation is conducted. In addition, the paper analyzes the functional relationships between regressed coefficient estimation and seat class and designed range of the corresponding airplanes. It further proposes the functional form of direct operation cost for aircraft type rank. In the last section, the OLS method is used to estimate the function’s coefficients. Compared with the NASA 97 method, the results on 4 specific aircraft types generating 10 sample points show that the maximum relative error is 0.086, which verifies the feasibility of the proposed model.

Key words: air transportation, direct operation cost, OLS method, seat class, designed range, flying distance
