UPDATE:

With the rapid spread of the 2019 Novel Coronavirus, related closures, and travel bans, we have decided to postpone the AdONE Summer School as the health and welfare of participants is our top priority.

We are actively considering alternative times and will communicate those when possible. Most likely, we will postpone the summer school by one year until July 2021. All information regarding the postponed school will be available here as soon as the timeline has been fixed.

Abstract

Mobility problems involve transporting users from their origin to the desired destination. As such, they planning the itinerary of vehicles that are used for the service. We will focus on mobility services performed by buses and/or minibuses which, contrary to tram or metro, are not forced to follow the path determined by the related network. In this case, the problem of determining the trips of the buses corresponds to a routing problem with pickup and deliveries or to a Dial-A-Ride Problem (DARP) (this last terminology being the most commonly used in the mobility literature).

We will investigate different Mixed Integer Linear Problem formulations (MILPs) for routing problems in general, showing the advantages and the drawbacks of each of them.  We will then move to formulations for the DARP. In addition, we will present ways to strengthen the formulations, namely through valid inequalities. Finally, we will show how MILPs can be used heuristically to build solution approaches capable of handling instances of larger size than the ones which are typically solved through exact approaches, avoiding, anyway, the burden of building ad-hoc heuristic or meta-heuristic algorithms. In particular, we will present different ways of building “easy to implement” matheuristics on top of a MILP formulations.

Maximilian Schiffer: Recent and Future Trends in Mobility and Transportation Systems

Maximilian Schiffer is Assistant Professor of Operations and Supply Chain Management at TUM School of Management, Technical University of Munich. Before joining TU Munich, he was a Visiting Postdoctoral Scholar at Stanford University and a Postdoctoral Scholar at RWTH Aachen University. Further, he is an Associate Member of the GERAD. He received a Ph.D. degree in Operations Research from RWTH Aachen University in 2017.  Maximilian’s expertise lies in in the field of Operations Research and Management Science, specifically in Dynamic Programming, (Mixed) Integer Programming, Metaheuristics, Robust Optimization, as well as Machine Learning and Forecasting, applied to a variety of complex application fields, e.g., Transportation Problems, Supply Chains, Production Networks, and Big Data. His research on electric vehicles and logistics networks with intermediate stops has been awarded with numerous prizes, e.g., the INFORMS TSL Dissertation Prize and the GOR Doctoral Dissertation Prize. Currently, Maximilian’s research focuses on the development of Operations Research and Prescriptive Analytics methods to solve central societal problems, especially in the field of mobility and transportation. To this end he focuses on electric vehicles, autonomous mobility on demand systems, and inter and multi-modal transportation, including multi-stakeholder perspectives. His interdisciplinary work in this field has been recognized beyond the field of Operations Research in Robotics and Transport Engineering, e.g., by a best paper award from the IEEE Conference on Intelligent Transportation Systems.

Short Bio

Marlin Ulmer is a Professor at the Business Department of the Technische Universität Braunschweig. He studied Mathematics in Göttingen and Swansea. His PhD-thesis at TU Braunschweig focused on the interface between Management Science, Mathematics, and Computer Science. It was awarded, amongst others, by the INFORMS TSL Society and the German OR Society. Marlin’s teaching and research interests comprise applications from the entire field of Urban Mobility and Logistics, Operations Research, Stochastic Optimization, Dynamic Decision Making, Approximate Dynamic Programming, and Machine Learning. He works with leading experts of these fields all over the world. Click here for his Google Scholar profile.

Abstract

Many urban mobility and logistics applications experience information changes over time, for example, when new mobility demand is revealed. Companies can adapt their plans to the new information, and if possible, can already anticipate future information changes in their planning. The corresponding mathematical models are (stochastic and dynamic) sequential decision processes.

We will discuss how to define, model, and solve sequential decision problems. We will focus on a set of selected applications from the field of urban mobility and logistics, amongst others, bike-sharing systems, same-day delivery, and dynamic dial-a-ride. We will review and analyze the existing methodology for solving sequential decision problems, for example, simulation procedures and approximate dynamic programming. We will also discuss and evaluate the suitability of different methodology with respect to problem and data characteristics. The overall goal is to get an overview over the field’s terminology and methodological toolkit while also getting an idea how to choose the “right” method for a specific problem.

Abstract

Vehicle routing problems have been the focus of extensive research over the past sixty years, driven by their economic importance and their theoretical interest. The diversity of their applications has motivated the study of a multitude of problem variants. In this talk, we will review some emerging VRP variants and heuristic solution techniques which are developed to tackle them. We will study the close connections between the structure of the problem decision sets and the solution methods, showing how heuristics can effectively perform a search in a reduced space defined by fewer groups of decision variables. Finally, we discuss recent research perspectives connecting machine learning, pattern extraction and local searches.
