摘要
构建了由2个风险规避的航空公司组成的航空联盟网络的决策模型,并利用均值-标准差(mean-standard deviation)风险度量准则建立了航空联盟成员的决策目标函数。首先,分析了航空联盟网络在集中决策下的均衡模型。研究发现航空公司的风险规避特性将会降低机票价格,进而减少联盟整体的效用。其次,研究了航空联盟实施收益共享机制下的分散决策模型,研究结果表明收益共享机制不仅可以实现联盟成员个人的效用最大化,同时可以达到联盟整体效用的最大化。研究还发现,实施收益共享机制可以提高航空联盟成员的绩效水平。绩效水平提升的幅度与价格弹性系数、国内与国际航线的运作成本的比值、航空公司的风险规避度及收益共享系数等因素密切相关。此外,通过数值分析研究了不同参数对航空联盟成员实施收益共享机制后提升的绩效水平的影响程度。
An airline alliance network consisting of two risk-averse airlines is addressed in this paper. A decision-making model for such a network is proposed. By using the mean-standard deviation risk measure criteria, a decision-making objective function for the airline alliance members is also established. First, an equilibrium model in the network is analyzed under the centralized decision-making. It is found that the risk aversion characteristics of airlines reduce ticket prices of airlines, thereby reducing the overall effectiveness of the airline alliances. Second, under the revenue sharing mechanism, a decentralized decisionmaking model in the airline alliance network is investigated. Result shows that revenue sharing mechanism can maximize not only the effectiveness of the individual alliance members, but also maximize the overall effectiveness of airline alliances. The revenue sharing mechanism can improve the performance of airline alliance members, which is closely related to the price elasticity coefficient, the ratio of operating costs in the domestic and international routes, the airline＇s risk aversion and the revenue sharing coefficient. In addition, numerical results determine that the effects of different parameters on the performance levels of the airline alliance members are different under the revenue sharing mechanisms.
