Design and Optimization of Underground Logistics Transportation Networks

Distributed Optimization in Transportation and Logistics Networks

Many important problems in communication networks, transportation networks, and logistics networks are solved by the minimization of cost functions. In general, these can be complex optimization problems involving many variables. However, physicists noted that in a network, a node variable (such as the amount of resources of the nodes) is connected to a set of link variables (such as the flow c...

Integration of Social Concerns in Collaborative Logistics and Transportation Networks

Freight transport optimization, long based solely on an economic approach, happen today through the integration of environmental and/or social concerns, in line with the objectives of sustainable development. In the case of Small and Very Small Enterprises, these objectives cannot be reached individually, and these companies have to join their efforts to find collective solutions. Therefore, th...

Network Design in Transportation and Logistics: Models and Algorithms

Network design problems in transportation and logistics are both complex and largescale—often containing millions, or even billions, of decision variables and tens of thousands of constraints. Finding optimal or near-optimal solutions to large-scale network design problems is challenging, if not impossible. To address this issue, we extend and bring together in a unified setting two complementa...

Underground Mining Transportation Systems

Integrated Transportation Network Design Optimization

Traditionally, the design of a transportation system has focused on one of the two systems that comprise the transportation architecture, the vehicle or the network design. However, to define a systems level architecture for a transportation system, it is necessary to expand the system definition during the design process to include the network definition, the vehicle architecture, and the oper...
