Abstract: City Logistics aims to reduce the negative impact of freight-vehicle movements on city-living conditions, particularly in terms of congestion/mobility and environmental impact, while not penalizing its social and economic activities and fostering an efficient and sustainable transportation system. More precisely, one aims to reduce and control the number of freight vehicles operating within the city, improve the efficiency of freight movements and their environmental footprint, and reduce the number of empty vehicle-kilometres in, out, and through the city. The optimized consolidation of loads of different shippers and carriers within the same vehicles and the coordination of the resulting freight transportation activities within the city are key strategies in achieving these goals. In this talk, we focus on the tactical planning of two-tiered City Logistics systems based on these ideas, and investigate the issue of explicitly integrating the variability associated to demand into the tactical-planning processes and models. We describe a two-stage modelling framework, and discuss a number of strategies to adapt the plan to the observed demand together with the associated recourse formulations. Algorithmic and managerial issues related to these formulations are also addressed.
Bio: Teodor Gabriel Crainic is Professor of Operations Research, Transportation, and Logistics at the School of Management of the Université du Québec à Montréal, Montreal, Canada. He is also Adjunct Professor at the Department of Computer Science and Operations Research of the Université de Montréal, Montreal, Canada, and the Institute of Economics of Molde University, Molde, Norway. Professor Crainic is senior scientist at CIRRELT, the Interuniversity Research Center for Enterprise Networks, Logistics and Transportation, and Director of its Intelligent Transportation Systems Laboratory. His research interests are in network, integer, and combinatorial optimization, meta-heuristics, and parallel computation applied to the planning and management of complex systems mainly in transportation, logistics, and telecommunication. He published extensively in these areas. Professor Crainic is Associate Editor for Transportation Science and Transportation Research Part C: Emerging Technologies, Area Editor “Parallel Computing” for the Journal of Heuristics, and serves on several other editorial boards. He co-founded the TRISTAN (TRienial Symposium on Transportation Analysis) and Odysseus (International Workshop on Freight Transportation and Logistics) series of international meetings. He is a member of the Royal Society of Canada.
