The time-dependent location-routing problem

The urban freight transport industry is rapidly growing due to the role it plays in the economic vitality of the cities. With rapid population increase in the urban areas, growth of road freight transportation has been inevitable. The way to route large trucks around and within urban centers is highly critical due to its immense social, environmental, and economic impacts. Despite its importance, it has become a challenge in big cities which from the research point of view, it has led to the emergence of the green vehicle routing problem and from the practical one, the authors observe that recently, many cities have invested on improving their transportation systems. However, at the same time that the urban freight transport is known to be responsible for congestion and pollution in the cities, it is itself a victim of logistic decisions. With cost minimization as the main focus in freight transportation planning, designing an efficient distribution network in which the least time is spent on the road network, by avoiding the traffic jam, has been of less concern. Focusing on this aspect, the goal of this paper is to develop a new mathematical model and solution algorithms for network design problems with traffic congestion considerations.
