“Decentralized optimization of multi-commodity flows over time” Over the last 15 years, research on collaborative logistics has gained traction and resulted in a wide variety of research contributions that assess the potential and benefits of supply chain collaboration on the efficiency and performance of logistics.  Existing methods, however, tend to assume a long-term commitment between a small, fixed group of companies (e.g., a group of companies operating a joint transport corridor by bundling volumes). While such an approach might be viable in specific, small-scale cases, it lacks scalability and limits a healthy competition. In this research, we want to focus on the tension field between the (unrealistic) idea of supply chain collaboration – and the large gains it brings – and complete decentralization.  The goal is to understand how (partial) decentralization can alleviate the limitations of fully centralized supply chain collaboration while preserving synergy creation as much as possible (e.g., by giving concrete incentives and providing the possibility for spontaneous interaction).

Unofficial story of Prof. dr. Pamela Habibović

Date: October 4, 2022
Time: 4:00 pm - 5:00 pm
Location: Hybrid
GUS@UM

Did you ever wonder about the real stories of your colleagues? Behind every success you can read on a CV, are the numerous failed attempts, challenges and lessons learned. And then there are also all the successes that no one ever hears about. Our guest for this session is our Rector Magnificus Prof. dr. Pamela Habibović.

16h: The unofficial story of Prof. dr. Pamela Habibović
16.40h: Q&A with the audience
17h: after talk with drinks/nibbles

Growing Up in Science is a regular speaker series with academics who are willing to share their “real stories”. The Maastricht Young Academy believes that sharing these stories is important because as a community, we can listen to each other, support each other and, thereby, learn from each other!

We are looking forward to it!

Prof. Dr. Frank Phillipson

Date: June 9, 2022
Time: 12:30 pm - 1:30 pm
Location: hybrid
OR-lunch

“From OR to quantum computing: Am I in a superposition or are those fields entangled?”

During this talk, prof. dr. Frank Phillipson will talk about his background and experiences in applying OR in telecommunication, logistics, defense and scheduling during the (almost) 25 years carreer at KPN and TNO. The lasts years, Frank made the shift to quantum computing applications and machine learning. He will tell you why he made this shift, what quantum computing is and how this can help solving optimisation problems and what the plans for his endowed chair ‘Computational Operations Research’ look like. ​

Academic citizenship with prof. dr. Bram Akkermans

Growing Up in Science:  Academic citizenship, by Prof. Dr. Bram Akkermans

The Maastricht Young Academy is on a mission: create a university-wide movement for more academic citizenship. Academic citizenship means that we take care of those around us. Crucial elements are, e.g., good leadership, mentoring and a policy that supports and values all service-related tasks that we – as good academics – fulfil on a daily basis.

Prof. Dr. Bram Akkermans (LAW) considers academic citizenship a top-priority in his daily professional live. During the session, he will not only convince you about the importance of academic citizenship, but also share his experiences on how you can make a difference!

Growing Up in Science is a seminar series by the Maastricht Young Academy. For more information on the Maastricht Young Academy and an overview of all our activities and events, please visit our website: https://www.maastrichtuniversity.nl/research/maastricht-young-academy

“Envy-free Pricing of Seats in a Planetarium”

In this talk, we study a geometric envy-free pricing problem with a single item demand. The aim of the seller is to maximize the revenue by assigning prices to points and by allocating customers to these points in an envy-free manner, i.e., every allocated customer receives a point of the highest possible utility and all non-allocated customers cannot afford any point. Next to the continuous problem, we consider a discrete version where customers purchase the tiles of a regular tessellation of the plane, e.g., squares of the grid or hexagons of the honeycomb. For the special case of continuous version of the problem, where all customers have the same preferred point, we introduce a dynamic programming algorithm solving the problem in polynomial time. For the discrete version of the problem, we extend the dynamic programming algorithm to the quasi-polynomial time approximation scheme.

Research seminar “unlock me”

Date: May 4, 2022
Time: 10:00 am
Location: Ecole de Gestion de l'Université de Liège
Research seminar

I will present research results and ongoing work with respect to joint speed optimization at inland waterway networks.

Abstract: “The time needed to traverse a set of river segments on the inland waterways depends not solely on the speed of the vessel under consideration, but is also heavily influenced by the interaction with other vessels near river obstacles (such as locks). During the seminar we will consider the perspective of the lock operators as well as the individual skippers and discuss the impact of collaboration on the efficiency of inland waterway operations. Moreover, we will set the stage for ongoing/future research on the idea of intertemporal collaboration.”

“Optimality of Quasi-Polynomial Time Algorithms”

Lars will talk about some future research ideas. In algorithm design, the classical notions of efficiency and inefficiency (polynomial running time and exponential running time) do not cover quasi-polynomial time algorithms, which lie in between them. This leaves the corresponding problems in an uncertain state. A lot of scientific effort goes into trying to improve these quasi-polynomial running times to polynomial ones, but little is done to show that some of these problems might not be solvable in polynomial time. What tools do we have to achieve such lower bounds?

Research seminar “Unlock me”

Research seminar

During this ENM research seminar, I will present my research on speed optimization and skipper collaboration on inland waterways.

Abstract
“The time needed to traverse a set of river segments on the inland waterways depends not solely on the speed of the vessel under consideration, but is also heavily influenced by the interaction with other vessels near river obstacles (such as locks).  During the seminar we will consider the perspective of the lock operators as well as the individual skippers and discuss the impact of collaboration on the efficiency of inland waterway operations.

The presentation will also cover joint work with Julian Golak, Alexander Grigoriev, Veerle Timmermans and Marieke Vonk.

“Toward the smoothed analysis of k-jump neighborhood”

In this talk, we consider the problem of scheduling jobs on identical parallel machines to minimize the makespan. We analyze a simple local search method w.r.t. the so-called k-jump neighborhood.  We will talk about the worst-case running time of the algorithm. The idea of the research is to see whether the worst-case running time can be improved by applying smoothed analysis.

What are the struggles that academics go through?

On the 21st of October 2021 at 4pm, the Maastricht Young Academy will host its ninth Growing Up in Science event. In this session, Dr. Aurelie Carlier, assistant professor at MERLN, will share her unofficial story.

Aurelie obtained her MSc in Biomedical Engineering in 2010 and her PhD degree in Biomedical Engineering in 2014, both at KU Leuven, Belgium. She is also the co-founder and vice-chair of FEM, a network to discuss and tackle gender issues.
