Climate change is one of the greatest environmental, economic, and social challenges of our time. Urban transportation has had a major negative impact on our environment—most of our air pollution comes from transport. This paper explores ways to move toward a more sustainable transport system by focusing on creating a more efficient and livable city and improving the environmental efficiency of...

Transportation networks have been developed during the recent decades with the rapid growth of economy. At the same time, the conflicts between different transportation modes were getting more and more intense. To describe the competition relationship in integrated transportation system, a multi-agent competition model was presented. It is important to provide decision support for regulators to...

This article adopts a family of surrogatebased optimization approaches to approximate the response surface for the transportation simulation input– output mapping and search for the optimal toll charges in a transportation network. The computational effort can thus be significantly reduced for the expensive-toevaluate optimization problem. Meanwhile, the random noise that always occurs through ...

The analysis of the most researches related to the supplier selection shows that very little attention is given to transportation although its cost may be significant important to this selection. In this paper, we present a multiobjective approach of selecting suppliers and allocating the order quantity among them, taking into account transportation. The objectives to minimize in the model are ...

Japanese companies in India are required to pay additional costs to avoid breakdown of machinery due to blackouts and voltage changes. The bad condition of roads inflicts damage on commodities during transportation. Transportation between Delhi and the South takes one week due to the lack of express highways. Economic losses are incurred because of the long transportation time and high gasoline...
