We study the problem of optimizing traffic in decentralized transportation networks, where the cost of a link depends on its congestion. If users of a transportation network are permitted to choose their own routes, they generally try to minimize their personal travel time. In the absence of centralized coordination, such a behavior can be inefficient for society and even for each individual us...

Many practical problems arising in real world applications, mainly in the fields of logistics and telecommunications, can be modeled as network design or vehicle routing problems. In this thesis we study three combinatorial optimization problems belonging to the classes of Network Design and Vehicle Routing problems that are strongly linked in the context of the design and management of transpo...

DynaMIT is a simulation-based real-time system designed to estimate the current state of a transportation network, predict future traac conditions , and provide consistent and unbiased information to travelers. To perform these tasks, eecient simulators have been designed to explicitly capture the interactions between transportation demand and supply. The demand reeects both the OD ow patterns ...

In logistics management, selecting the carriers to deliver freight is a critical process for global enterprises. This paper determines the optimal carrier selection based on a multi-commodity reliability criterion for a logistics network subject to budget. Traditionally, a logistics network includes nodes and routes connecting the supplier and customer. Along each route, several carriers are av...

Introducing electric vehicles (EVs) into urban transportation network brings higher requirement on travel time reliability and charging reliability. Specifically, it is believed that travel time reliability is a key factor influencing travelers' route choice. Meanwhile, due to the limited cruising range, EV drivers need to better learn about the required energy for the whole trip to make decisi...

The past decade has seen a sharp increase in the level and volatility of commodity prices (Graph 1). This has occurred alongside a sharp increase in commodity demand from emerging market economies, but also in parallel with a rapid increase in both commodity derivatives trading and financial investor activity in commodity markets (Domanski and Heath 2007; Dwyer, Gardner and Williams 2011). That...

This paper proposes a novel facility location model for health service network design by considering different key elements including the reliability aspects, service capacity, congestion, service quality, surrounding public infrastructures, geographical accessibility and several types of cost such as investment, transportation and operational costs. We formulate the problem as a robust scenari...

1. The second question suggested by the analytical framework is whether market failures will result from decreases in the prices of commodity outputs, in a context of agricultural policy reform. To answer this question, we need to know: (1) how price decreases will affect the level of production of both commodity and non-commodity outputs, and (2) what is the value of the resulting reduction in...

Transportation ridesharing network modeling tool, abbreviated as TransRNM, provides a framework to predict the flow and demand pattern of urban transportation networks with services, referred network. The prediction traffic travel in context is vital for modern planning management. TransRNM flexible interface define networks, any specific multiple structures, costs, choice behaviors, elasticity...

Transportation networks play a crucial role in human and animal societies. For a transportation network to be efficient, it must have adequate capacity to meet traffic demand. Network design becomes increasingly difficult in situations where traffic demand can change unexpectedly. In humans, network design is often constrained by path dependency because it is difficult to move a road once it is...
