Tutorials
The role of the tutorials is to provide a platform for a more intensive scientific exchange amongst researchers interested in a particular topic and as a meeting point for the community. Tutorials complement the depth-oriented technical sessions by providing participants with broad overviews of emerging fields. A tutorial can be scheduled for 1.5 or 3 hours.

Brief Bio
Prof. Asvin Goel is Associate Professor of International Logistics at Jacobs University and Adjunct Professor of Supply Chain Management at the Zaragoza Logistics Center in Spain. He holds academic degrees from the Faculty of Mathematics at the University of Göttingen (Dipl.-Math.), from the Faculty of Mathematics and Computer Science at the University of Leipzig (Dr. rer. nat.), and from the Faculty of Law, Economics, and Business at the University of Halle-Wittenberg (Dr. rer. pol. habil.). He has several years of working experience as an independent consultant and software developer for the logistics industry. From 2006 to 2008 Prof. Goel was Visiting Associate Research Professor within the MIT-Zaragoza International Logistics Program and served as principle investigator of the research project "In-Transit Visibility" which was jointly conducted by DHL Exel Supply Chain, Deutsche Post World Net, the MIT Center for Transportation and Logistics, and the Zaragoza Logistics Center. In 2009 he was invited as Visiting Researcher to the National ICT Australia (NICTA) in Sydney and in 2010 he was Visiting Researcher at the Centre Interuniversitaire de Recherche sur les Réseaux d’Entreprise, la Logistique et le Transport (CIRRELT) in Montréal.

Abstract
Abstract:
Economic pressure forces transport companies to maximise vehicle utilisation and minimise labour costs. Both goals can be achieved by optimizing vehicle routes and schedules using sophisticated algorithms. Highly optimized routes and schedules, however, often eliminate idle times to such an extend that drivers do not have enough time to regularly take breaks and rests. The absence of sufficiently long breaks and rests can lead to truck driver fatigue and reduced road safety. This tutorial shows how work schedules can be assessed with respect to their accident risks and shows how vehicle routes can be optimized without impairing road safety. It gives an overview over different hours of service regulations world wide and identifies common types of constraints imposed by these regulations. A general framework is presented that can be used to model the constraints and it is shown how typical solution procedures for vehicle routing problems can be adjusted in such a way that the resulting routes and schedules comply with the regulations. Furthermore, a comparison of the impact of different hours of service regulations world wide is given and open research questions are discussed.
Keywords:
Vehicle routing, Fatigue/Risk models, Hours-of-service regulations
Aims and Learning Objectives:
Participants will learn why it is important to explcitly schedule breaks and rests when optimizing vehicle routes and will learn how constraints imposed by hours of service regulations can be considered within typical solution procedures for vehicle routing problems.
Target Audience:
Students, researchers, and practitioners interested in rich vehicle routing problems including real-life constraints such as hours of service regulations.
Prerequisite Knowledge of Audience: Participants are expected to have basic knowledge in vehicle routing problems.
Detailed Outline:
1. Introduction to road safety and fatigue/risk models
2. Overview of several hours of service regulations world wide
3. Modelling of hours of service regulations
4. Hours of service regulations in vehicle routing
5. Evaluation of accident risks of different regulations
6. Discussion of open research questions.
Related Experiences:
Prof. Goel developed software for the trucking industry including the estimation of arrival times considering real-time GPS data and hours of service regulations. Furthermore, he has published several papers on hours of service regulations in leading journals such as Transportation Science and Transport Policy. His recent paper "A. Goel and T. Vidal, Hours of Service Regulations in Road Freight Transport: An Optimization-based International Assessment, Transportation Science 48(3), p. 391-412, 2014" won the INFORMS TSL Best Paper Award 2014.
