Train path (infrastructure), rolling stock and crew scheduling are three critical planning decisions in railway transportation. These resources are usually planned separately in a sequential process that typically starts from planning (1) train paths and goes further on to (2) rolling stock and (3) train drivers. Such a sequential approach helps to handle the complexity of the planning process ...

Since railway transport possesses the advantage of high volume and low carbon emissions, diverting some freight from road to railway will help reduce the negative environmental impacts associated with transport. This paper develops a flow assignment model for quantitative analysis of diverting truck freight to railway. First, a general network which considers road transportation, railway transp...

As the intelligent railway is the trend of current railway development, the paper aims to show an overview of the Railway Intelligent Transportation System (RITS) in China. Firstly, the current transportation situation in China is given and then some basic concepts of RITS are talked about as well. Secondly, the necessity of RITS is analyzed to show its strategic position. Then, the overall arc...

Railway and metro transport systems (RS) are becoming one of the popular choices of transportation among people, especially those who live in urban cities. Urbanization and increasing population due to rapid development of economy in many cities are leading to a bigger demand for urban rail transit. Despite being a popular variant of Traveling Salesman Problem (TSP), it appears that the univers...

We have designed and implemented a distributed model for planning and scheduling of transports in a railway company which is usable also for other production planning problems. Our model emphasizes the use of an agent for the coordination of distinct sub-problems occurring in railway scheduling such as for instance the allocation of track resources to transports, the allocation of vehicles to t...

The railway transportation planning under the fuzzy environment is investigated in this paper. As a main result, a new modeling method, called minimum risk chance-constrained model, is presented based on the credibility measure. For the convenience ofs olving the mathematical model, the crisp equivalents ofc hance functions are analyzed under the condition that the involved fuzzy parameter...

In 2012, a survey was carried out in 8 French cities to study noise annoyance due to combined transportation noise sources. Both partial and total annoyances were measured. The current paper will first focus on partial noise annoyance due to railway traffic measured in 6 French cities. In order to predict annoyance due to single transportation noise sources, the European Commission recommends t...

in this article, multiple-product pvrp with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. a mathematical formulation was provided for this problem. each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. to solve the problem, two meta-heuristic methods...
