城际铁路票额随机分配优化

Optimization for Randomized Allocation of Intercity Railway Ticket

票额分配是实现城际铁路效益最大化以及调整和优化列车开行方案的基本依据之一,同时也是适应城际客流需求的重要手段之一。在分析实际分配方法和确定式的整数分配票额模型难以适应城际客流需求的基础上,提出以实际客流情况为依据的弹性票额分配方法,将实际乘车客流量视为不确定因素即将其视为正态分布,建立随机整数规划模型并采取转化为确定性等价方法进行求解,使得整个列车票额收益最大化。以沪宁城际高速铁路高峰时段某列车为例得到验证。票额随机分配模型将为城际铁路票额分配提供新的思路和方法。

Ticket allocation is to achieve maximum efficiency and is a fundamental basis of adjustment and opti-mization of train in inter-city railway.It is also an important means to adapt to inter-city passenger demand.However,actual allocation and the integer allocation model cannot adapt to the needs of inter-city passenger.Based on the actual passenger,the paper apopts the actual car traffic as uncertain factor,which is a normal dis-tribution,and proposes a flexible method of ticket allocation,which establishes the stochastic integer program-ming model to make a resolution by transforming into a certain equivalent method to maximize the whole train ticket revenue.The Shanghai-Nanjing Inter-city express train is taken as an example to be verified.Ticket ran-domized optimization will provide new ideas and methods of intercity railway tickets allocation.
