摘要
为保证机场所有出租车的收益均衡,机场允许短途载客出租车返回优先再次载客。为判定返回机场的出租车能否享有优先权,提出了最大短途载客距离即短距阈值的概念。利润的方差最小时各出租车的收益就会更加均衡。基于这个数学理论,文章建立了利润方差最小的随机优化模型,并提供了求解算法设计。以成都双流国际机场出租车为例,对模型进行实证分析。通过计算得到机场出租车载客短途阈值为13.6km。最后通过讨论发现,该模型具有较强的应用性,值得推广。
In order to ensure the income balance of all taxis at the airport,the airport allows short-distance passenger taxis to return and give priority to carrying passengers again.In order to determine whether taxis returning to the airport can enjoy priority,the concept of maximum short-distance passenger distance,i.e.short-distance threshold,is put forward.When the variance of profit is the smallest,the income of each taxi will be more balanced.Based on this mathematical theory,this paper establishes a stochastic optimization model with minimum profit variance,and provides a solution algorithm design.Taking the taxi in Chengdu Shuangliu International Airport as an example,the model is empirically analyzed.Through calculation,the short-distance threshold of airport taxi passengers is 13.6km.Finally,through discussion,it is found that the model has strong application and is worth popularizing.
