摘要
针对不确定环境下的机场群航空客流分配问题,考虑旅客在全出行链上的出行延误,综合评估旅客的出行成本并建立出行效用函数,根据随机用户均衡原理构建了机场群航空客流均衡分配模型,最后设计基于变分不等式的投影收缩算法对模型进行求解.将模型应用到有长短途航线的机场群出行交通网络中,实例验证了所提出模型和算法的有效性.算例结果表明:调整地面交通水平、机场服务效率、航班飞行时间可靠性等措施可以降低旅客延误成本,促进客流在机场群中均衡分布.
To explore the influence of the uncertainties of multi-airport systems on passenger fow distribution,this paper evaluates the delay cost of passengers from the perspective of air travel chain,and establishes the travel utility function of air passengers by jointly considering travel time,travel cost,and delay cost.Then,we present an equilibrium passenger flow distribution model based on the stochastic user equilibrium theory,which is transformed into variational inequality and solved by the projection and contraction algorithm.Numerical experiments are carried out on a traffic network of a multi-airport system with long and short-haul,verifying the practical applicability of the proposed model and algorithm.The results show that the improvement of the ground transportation level of multi-airport system,the service level of regional airports and flight time reliability are all helpful to reduce the travel delay of passengers and promote the balanced distribution of passenger fow in the multi-airport system.
