MULTI-OBJECTIVE PROGRAMMING FOR AIRPORT GATE REASSIGNMENT

To improve the efficiency of gate reassignment and optimize the plan of gate reassignment,the concept of disruption management is introduced,and a multi-objective programming model for airport gate reassignment is proposed.Considering the interests of passengers and the airport,the model minimizes the total flight delay,the total passengers′walking distance and the number of flights reassigned to other gates different from the planned ones.According to the characteristics of the gate reassignment,the model is simplified.As the multi-objective programming model is hard to reach the optimal solutions simultaneously,a threshold of satisfactory solutions of the model is set.Then a simulated annealing algorithm is designed for the model.Case studies show that the model decreases the total flight delay to the satisfactory solutions,and minimizes the total passengers′walking distance.The least change of planned assignment is also reached.The results achieve the goals of disruption management.Therefore,the model is verified to be effective.     

从亚特兰大中枢看白云机场的建设与发展

近年来,位于亚洲太平洋地区的香港、仁川、成田、新加坡、北京以及浦东机场对亚太航空枢纽地位的竞争较为激烈,香港、仁川、成田和新加坡机场已经取得了良好的发展业绩,并初步确立了他们的枢纽地位,北京和浦东机场在举办2008年奥运会和2010年世博会的促进下,发展势头也非常迅猛,而广州白云机场在亚太航空枢纽的竞争方面面临的压力很大。因此学习和借鉴国外成功的机场建设和管理经验,加快白云机场自身的发展步伐,对促进广州白云机场建设东南亚及太平洋地区重要枢纽机场目标的实现有重要的现实意义。美国亚特兰大机场(Hartsfields-Jack-sonA…     

停机位容量评估及其包络线分析

为客观评估停机位系统保障能力,探索机位容量提升方法,将进出港航班的地面作业时间、停机位缓冲时间及航班定位时间引入到容量模型,设计了一种改进型的停机位系统容量评估模型。以国内某机场为例,使用停机位容量包络线方法,分别从进出港航班比例变化、机型组合比变化、机位利用率和航班平均机位占用时间同时变化三个方面,对停机位系统的容量进行了评估分析。使用该模型和容量分析方法,可以为机场运行管理人员在制订机位容量提升计划、组织高峰时段航班运作及制订中远期机位规划等方面提供有益的决策支持。
