Title: Economic and environmental sustainability of freight transport in Europe
Abstract: The demand for transportation in Europe is continuously increasing, which puts a high pressure on the European transport ecosystem. Therefore, the European Union wants to ensure economic growth while at the same time mitigating the strains put on economic, environmental and social sustainability of companies. Therefore, the European Commission supports research in this area within the European Union in its 7th framework program (FP7). The Institute for Production Management of WU Vienna has been participating in two related research projects, namely “LOGMAN” and “GET-Service”.

The FP7 project “LOGMAN” aims at identifying “Logistics and Manufacturing Trends” and their impact on sustainability in supply chains. Whereas some trends and best practices (e.g. offshoring), have turned out to be advantageous in the past concerning economic criteria, they have also increased transport activities and, consequently, greenhouse gas emissions. In the course of the project, case studies with European companies from different industries have been conducted. The identified trends and best practices have then been analyzed according to their effects on economic and environmental sustainability based on a three-dimensional framework. This framework consists of financial economic criteria (e.g. total costs), non-financial economic criteria (e.g. service levels) and environmental criteria (e.g. CO2 emissions). Based on that, scenarios have been developed and evaluated using macro-economic transport- and emission-models in order to derive recommendations for pan-European transport policies.

The currently ongoing FP7 project “GET-Service” approaches the goal of achieving economic and environmental sustainability in freight transportation from a micro-economic perspective. It is the goal of this project to develop an integrated information platform that facilitates increased “Green European Transportation”. This information platform will greatly simplify the provisioning and the exchange of information between transport planners, professionals and governmental bodies, in particular focusing on the exchange of information between different organizations. To make this possible, the platform will provide facilities for (real time) information sharing, transport planning and control, thus enabling companies to increase the efficiency of their transportation and to react quickly to unexpected events. This will lead to faster and safer freight transportation in Europe, which, consequently, has positive effects on the overall traffic situation, but also on congestion and on CO2 emissions.

Title: Timetable Synchronization for rail mass transit
Abstract: We propose a mixed integer programming (MIP) optimization model for a timetable synchronization problem for rail mass transit. The objective is to minimize the sum of all waiting times of all passengers at interchange stations. By adjusting the trains’ run-times and station dwell-times during their trips, and their dispatch times, turnaround times and headways at the terminals, we can construct high-quality timetables. A novelty in our formulation is the use of binary variables to determine the relative sequencing of trains on different lines with passenger transfers, which enables the correct representation of the waiting times for transfers to the “next available” train at interchange stations.

With trains departing every few minutes from each terminal, there are a large number of trips to consider, and hence the MIP formulation for the timetable synchronization contains thousands of binary variables and tens of thousands of continuous variables and constraints. We also investigated an optimization-based heuristic for this problem, whereby we can get good-quality solutions within a reasonably short time.

The train schedule for the MTR system in Hong Kong is used as an illustrative example, which indicates that our approach improves the synchronization of the current schedule significantly. We also explore the trade-offs among different operational parameters and flexibility and their impact on overall passenger waiting-times.

Professor Werner JAMMERNEGG
Dr. Werner Jammernegg studied Business Administration at University of Graz and Technical Mathematics (Information Processing) at Graz University of Technology, Austria. Besides two master degrees, he holds a doctoral degree in Business Administration and a habilitation degree in Operations Research and Statistics. He has been Professor of Operations Management at WU (Vienna University of Economics and Business), Austria, since 1990. In 1998, he rejected an offer from KIT (Karlsruhe Institute of Technology), Germany, for a full professorship of Manufacturing Management. Since 2008 he has been head of the Institute for Production Management and since 2010 he has been director of the Master´s of Science program in Supply Chain Management at WU.
The teaching and research interests of Dr. Jammernegg include Production and Operations Management, Supply Chain Management and Stochastic Modelling. He has published on these and related topics in refereed international journals such as Annals of Operations Research, Decision Support Systems, European Journal of Operational Research, International Journal of Production Economics, Journal of Economic Dynamics and Control, Omega, Review of Economics and Statistics, Review of Managerial Science and Total Quality Management. Recently, Dr. Jammernegg has been participating in three research projects on the economic and environmental sustainability of long-distance freight transport, sponsored by the European Union under the seventh Framework program (Freightvision, LOGMAN, GET-Service). He is also the co-author of two introductory textbooks o

Professor Janny M.Y. LEUNG 梁美兒
Janny Leung is Professor, Systems Engineering and Engineering Management Department, The Chinese University of Hong Kong. She obtained an S.B. degree in Applied Mathematics from Radcliffe College, a B.A. in Mathematics from Oxford University and a Ph.D. in Operations Research from the Massachusetts Institute of Technology. Before returning to Hong Kong, she was a faculty member at Yale University and the University of Arizona.
Her main research interests are combinatorial optimisation and logistics; she has investigated problems in public transit scheduling, supplier selection, material handling, routing and distribution planning, facility layout, production scheduling and baseball time-tabling.
