DESCRIPTION:Prof. Konstantinos G. Zografos\nThe shipment of hazardous mate
 rials constitutes a serious transportation safety problem. Although hazard
 ous materials accidents are rare\, their consequences (e.g.\, fire\, explo
 sion\, chemical spills) are severe and may endanger human lives and/or cau
 se property damage and environmental pollution. Planning safe truck routes
  is considered an effective\, pro-active risk mitigation measure. Thus\, h
 azardous materials transportation and distribution decisions\, in addition
  to conventional business objectives\, should also consider risk minimizat
 ion objectives. Hazardous materials routing problems can be grouped into t
 wo broad categories: i) single origin-single destination full truckload an
 d ii) single origin-many destinations less than truckload. Although substa
 ntial research effort has been devoted to the former category\, limited wo
 rk has addressed the latter. In this talk\, we present the evolution of ha
 zardous materials routing and scheduling models and we propose a new formu
 lation that takes into account the multi-objective nature of hazardous mat
 erials routing decisions and the dynamic characteristics of the underlying
  roadway network. The hazardous materials distribution problem is formulat
 ed as a bi-objective\, time-dependent vehicle routing and scheduling model
  with time windows. A heuristic algorithm was developed to solve the propo
 sed model. Computational results from the application of the proposed algo
 rithm to problem instances of realistic size are also presented.\n\nBio: K
 onstantinos G. Zografos is Professor at the Department of Management Scien
 ce and Technology of the Athens University of Economics and Business and D
 irector of the Transportation Systems and Logistics Laboratory. His profes
 sional expertise\, research and teaching interests include Applications of
  Operations Research and Information Systems in Transportation Systems and
  Logistics Management. He has published more than 100 papers in academic j
 ournals and conference proceedings. Professor Zografos has served as a con
 sultant to governmental agencies\, companies and international organizatio
 ns\, in USA\, Europe and Greece and has been involved as a principal inves
 tigator in more than 60 R&D projects. He has received the ENO Foundation f
 or Transportation award\, the 2005 President's Medal Award of the British 
 Operational Research Society\, the Edelman Laureate Honorary Medal of INFO
 RMS in 2008 for significant contributions to Operations Research\, and oth
 er awards.
