This study examined the economic and environmental efficiency of 27 global airlines in 2010. An extended environmental slacks-based measure data envelopment analysis model with the weak disposability assumption was developed to assess the efficiency of the airlines. Asia-based airlines are generally more efficient, followed by European and American airlines. The poor fuel consumption is a major…
Numerous studies have analyzed the productivity, efficiency, and competitiveness of ports. However, empirical studies on the environmental efficiency of ports have not yet been carried out, since all previous studies have not considered the undesirable outputs that ports generate, for instance, CO2 emissions. To fill the gap in the literature, the objective of this study is to estimate environm…
Numerous countries have implemented or are considering a range of policies to lower emissions from transportation. An analysis of the impacts of environmental regulation is a crucial issue, which has not been properly highlighted in the transportation literature, particularly in terms of the foregone output by such regulation. This study develops a novel DEA model that measures the foregone out…
The objective is to identify the factors affecting shipping companies’ port choice based on a survey to a sample of shipping companies. Six factors were considered relatively important: local cargo volume; terminal handling charge; berth availability; port location; transshipment volume and feeder network. Exploratory factor and confirmatory factor analyses identified five port choice categor…

This paper considers a multimodal transportation problem, which is the problem of determining the transportation flow, i.e. volume of container cargoes, and the transportation mode in each trade route, for the objective of minimizing the sum of shipping and inland transportation costs. The problem takes account of two restrictions: maximum cargo volumes capacitated at each seaport and maximum n…
