桃园机场航厦下方捷运扩挖隧道施工案例

在桃园国际机场第二航厦下方,预留了捷运机场线的隧道,由于新规划的路线改变,需要扩大该隧道断面;这项扩挖隧道工作位于卵砾石地层,有11m高的水头;结构的宽度由4 m扩大至18.4 m,总开挖量约有7 927 m3。为了确保第二航厦结构及营运安全,新设了避雷接地网、重型托基支撑架及安全监测系统等;并藉由袪水、双环塞固结灌浆及防洪安全门等工程措施,辅助钻石链锯进行镜面破除切割。开挖过程中对于开挖壁面保护,则采用喷凝土、自钻式岩栓及垂直钢支撑,构成了临时开挖主要支撑系统。介绍隧道扩挖施工,细部工作内容及经由施工得到的许多宝贵经验。

Robust flight-to-gate assignment using flight presence probabilities

In this paper we present a novel method to improve the robustness of solutions to the Flight-to-Gate Assignment Problem (FGAP), with the aim to reduce the need for gate re-planning due to unpredicted flight schedule disturbances in the daily operations at an airport. We propose an approach in which the deterministic gate constraints are replaced by stochastic gate constraints that incorporate the inherent stochastic flight delays in such a way so as to ensure that the expected gate conflict probability of two flights assigned to the same gate at the same time does not exceed a user-specified value. The novel approach is integrated into an existing multiple time slot FGAP model that relies on a binary integer programming formulation and is tested using real-life data pertaining to Amsterdam Airport Schiphol. The results confirm that the proposed approach holds out great promise to improve the robustness of the FGAP solutions.

Simulation-based assessment methodology to improve ground service operations at a hub airport

ABSTRACT

Airport terminals are dynamic environments and security/passport services generally constitute costly bottlenecks in terminals. Increases in the number of airline passengers compels airport terminals to provide more efficient services to its customers under space and resource limitations. This study examines the level of service of passenger processes at Istanbul Atatürk Airport by constructing a comprehensive simulation model. It focuses mainly on passport control services and passenger transfer security services because of the airport's hub status and the strategy of Turkish Airlines. The increasing number of transfer passengers may cause disruptions in departure flight schedules due to slow passenger processes. After validating the model, we investigate the consequences of three main alternative solutions, including 17 sub-scenarios, to capture target quality levels. Finally, we provide the results for each scenario to investigate the optimum allocation of resources to terminal operations.     

A choice model of airline passengers’ spending behaviour in the airport terminal

This study examines the influence of passengers’ travel-related factors, their intention to shop and the impact of socio-economic factors on their consumption behaviours while at the airport terminal. Three categories of consumption model – shopping, dining and airport entertainment – are developed to analyse different consumption behaviours. The results show that free time is the main factor that influences passengers to choose entertainment while waiting at the terminal, and the use of airline lounges has a negative influence on the extent of engagement in all three types of passenger consumption behaviour, especially dining. Furthermore, passengers’ dining expenditure has a positive effect on the extent of engagement in entertainment, but a negative influence on the extent of engagement in airport shopping. Passengers’ preferences of airport shopping area after they have cleared security is positively associated with the extent of engagement in both shopping and entertainment but negatively associated with the extent of engagement in dining activities.
