Environmental Impact and External Costs Associated with Hub-and-Spoke Network in Air Transport

چکیده
Under the background of economic globalization, air transport industry developed rapidly. It turns out that city-to-city network has not been able to adapt well development society, and hub-and-spoke came into being. The demonstrates advantages reducing operating costs airlines keep a competitive advantage, by maintaining interests in rapidly developing context. However, during operation aircrafts, they consume fuel spew great deal harmful pollutants air, which an adverse impact on living environment. This paper explores external associated with from environmental perspective. With some mathematical models, we construct take quantitative study transport. For calculating pollutant emissions, meteorological conditions were considered revise emission factors Engine Emissions Data Base (EEDB) published International Civil Aviation Organization (ICAO). measurement model is employed calculate externality toxic gas greenhouse (GHG). In order make more convincing, two alternative networks are computed: network. found poorer because different characteristics scale fleets. Therefore, under general trend green aviation, provides certain reference for airlines’ strategic decision-making.

A passenger demand model for air transportation in a hub-and-spoke network
This paper develops an air passenger model that deals with city-pair demand generation and demand assignment in a single framework. Using publicly available and regularly collected panel data, the model captures both time series and cross-sectional variation of air travel demand. The empirical analysis finds that pattern of correlations among alternatives can be described by a three-level neste...
متن کاملEuclidean Hub-and-Spoke Networks
The hub-and-spoke distribution paradigm has been a fundamental principle in geographic network design for more than 40 years. One of the primary advantages that such networks possess is their ability to exploit economies of scale in transportation by aggregating network flows through common sources. In this paper, we consider the problem of designing an optimal hub-and-spoke network in continuo...

HLP (hub location problem) tries to find locations of hub facilities and assignment of nodes to extended facilities. Hubs are facilities to collect, arrange, and distribute commodities in telecommunication networks, cargo delivery systems, etc. Hubs are very crucial and their inaccessibility impresses on network whole levels. In this paper, first, total reliability of the network is defined bas...

Maritime cabotage is a legislation published by a particular coastal country, which is used to conduct the cargo transportation between its two domestic ports. This paper proposes a two-phase mathematical programming model to formulate the liner hub-and-spoke shipping network design problem subject to the maritime cabotage legislations, i.e., the hub location and feeder allocation problem for p...
