灾害性天气下航空公司天气成本测算模型

A calculation model for airlines’ weather-related costs under disastrous weather conditions

为减轻灾害性天气对航空公司的影响,进一步提高经济效益,构建一种天气条件下航空公司的运营成本测算模型。首先,将航空公司运营成本重新划分为常规成本和天气成本2大类;然后,分析正常天气成本与非正常航班状态成本,得到给定情景航班的天气成本,累加所有航班天气成本,得到整个航空公司的天气成本,并重点关注灾害性天气下航空公司可降低的天气成本;最后,开展国内某中型航空公司的简单仿真案例研究。结果表明:该模型能够比较合理地计算航空公司可降低的天气成本;航空公司天气成本与其计划航班起降机场的灾害性天气危险性密切相关。

In order to mitigate the impact of disastrous weather on airlines and improve their economic efficiency,this paper proposes a calculation model for airlines’weather-related costs.Firstly,the airlines’operating costs were reclassified into two categories:regular operating costs and weather-related costs.Then,weather-related costs for a flight under a given scenario was calculated by analyzing its cost in normal weather and abnormal flight status cost.The weather-related costs of one airline was obtained by summing up the costs of all flights,focusing on the reducible weather-related costs under disastrous weather conditions.Finally,a simulation case study of a medium-sized airline in China was carried out.The results show that the reduced weather-related costs of airlines can be calculated by the proposed model reasonably,and the weather-related costs are closely linked with the weather hazard degree of departure and arrival airports of planned flights.
