Transportation hub networks are important for many large-scale logistics and supply chain systems. Basic hub location models rely on some key assumptions about the transportation cost that limits their practicality We present a new model for hub location and network design that uses fixed and variable transportation costs on all arcs, fixed costs for hubs, and also allows direct arcs. This approach...
Scientific evaluation of the hub airport Competence is the important prerequisite and basis of enhancing the Competence of the hub airports. The paper first clearly defines and analyzes the conception and characteristics of the hub airports. Based on the critical success factors of the hub airports, the paper builds a hub airport Competence evaluation index system and establishes a multiple criteria...
As the maximum flow could be the indicator of congestion possibility, the theoretical study of major airport was how to determinate the maximum flow when the parameter changed. Then, a discrete time loss queuing algorithm of airport was proposed, which calculated maximum flow with deducting probability transfer matrix of flight arrival rate and airport service rate. Compared to the existing general...
This paper mainly studies the algorisms of detecting and resolving air traffic conflicts. First of all, it generalizes the background and contemporary process of research in this field. Then, it establishes the flight prediction algorism via force directed method and writes the computerized prediction program based on VB.NET to verify the authenticity of this algorism. Finally, in accordance with...
Firstly, an air passenger capacity investigation at the capital international airport is made, and a composite forecasting model based on total air passenger capacity is established, in which multiple regression and ARIMA model are parallel connection and their forecast results are series connection with BP neural network. Secondly, according to the average growth rate of air passenger capacity, all...
This paper puts forward a two-stage correlative DEA model to measure airport production efficiency. The complicated production process of decision-making units is decomposed into two sub-processes. The correlative DEA model is used to evaluate the airport production efficiency by considering the co-relationship of sub-processes within the whole production process; an empirical study on 8 airports...
We consider a situation in which the booking requests from different fare classes arrive concurrently and two hotels compete with each other. Under this game theoretic setting, this problem was formulated as a two-player two-fare-class dynamic game. The main contributions can be presented as follows. First, each hotel's optimal future revenue is a non-decreasing function of its own room inventory...
In view of the analysis on agglomeration and diffusion of airport on economy, this article firstly abstracts the spatial scope of airport economic zone as the attraction domain of airport. Based on the completely unconstrained model and the development characters of the airport economic zone, secondly this article brings forward the theoretic model of the spatial scope of airport economic zone. Finally...
The most significant energy consuming infrastructures and the greatest contributors to greenhouse gases in the US today are electric and freight/passenger transportation systems. Technological alternatives for producing, transporting, and converting energy for electric and transportation systems are numerous. Selecting from among them requires long-term assessment since these capital-intensive infrastructures...
Previous studies of the US Air Transportation System have tried to identify rational airline behavior during times of significant economic and regulatory change. That research indicated that even during periods of increased fuel prices and slot controls at the New York Airports, the airlines chose to reduce the size of the aircraft rather than reduce schedule and increase aircraft size. This study...
This model estimates the ton-km required for each sector in the US economy which is important in understanding freight movement, modal resiliency, the relative dependence on transportation and transportation choices for various products and services. Relating this estimated freight movement to energy requirements and greenhouse gas emissions may lead to more effective policies in reducing the freight...
Modern supply chains depend on efficient, reliable and extensive freight transportation systems. Many of these systems utilize hub-and-spoke networks to provide transport between many origins and many destinations. These networks include hub facilities that provide a connecting, sorting and consolidation function which concentrates flows on the inter-hub links, called hub arcs, to exploit the economies...
Emergencies have been bringing huge damage, even worse when emergency event chain reaction is formed. Different emergency evolution models have been studied in the systematic perspective to find out common characters and correlation among four various emergency events. We propose an academic framework with four hierarchies including single event, event chain, event network, and event supernetwork...
A Free Trade Zone (FTZ) is an economic zone that an international business can utilize to optimize its supply network. It provides the advantages of operation efficiency as well as financial benefits. For these reasons, many international businesses choose to locate their manufacturing factories or distribution centers in an FTZ. However, the deployment of business sites in such an area necessitates...
The difficulties of accessibility still exist in air travel, although it has been available to most people today. This paper is aiming to construct an economical scheduling algorithm of the movement of wheelchairs and escorts throughout a day, and find the minimum budget of costs. After describing the general situation in Epsilon Company, this paper divided the costs into five parts. For each part,...
This paper introduced a two-stage stochastic model to address the strategic air freight network design problems under stochastic demand. Most of existing approaches for the airline network design problems are restricted to deterministic environment. However, the demand in airline market usually varies seasonally. The first stage of the proposed model is to determine the number and the location of...
In this paper, we study the asymptotical optimal solutions for the general airline revenue management problem, considering both customer cancelations and no-shows. We study a simple case where there is only one fare-class; the management controls the opening and closing of the fare-class, with the objective of maximizing the total revenue. We first develop a fluid control problem, where the customer...
In this paper, according to the principle of ICAO which named as "user paid for by himself", the model of aircraft economic classification is set up based on the theory of support vector machine (SVM). Then, in China, the model is used in the practice, the testing result is able to reflect out accurately characteristics of the data, and closely with the value of passenger enjoyed services.
In this paper, based on relevant assumptions, the maximum profit function (MPF) among different code sharing options has been established , in which the optimum fare can be gained to calculate the airlines maximum profit. Then the results would be tested by the air passengerspsila welfare function. Finally, the method is applied in practice successfully.
With the development of air traffic transportation industry, present design capacity can not meet future demand. Multi-airport system is the research object of this paper. The main influencing factor of multi-airport system capacity is partial route legs have less capacities. This paper combines the restricted optimization method of simultaneous perturbation stochastic approximation (SPSA) and hierarchical...
