14/07/2017 @ 13:40 - 14:45 - A New Formulation for Planning Electric Power Generation Schedules* Guglielmo Lulli Lancaster University July 14, Friday 13:40 EA-409 The Unit Commitment (UC) problem, which is the problem of planning electric power generation schedules, has attracted intense research for many decades. Lagrangian Relaxation was the prominent methodology to solve this class of problems, but more recently [...]
07/04/2017 @ 13:30 - 14:30 - Facility Location and Item Prepositioning for Humanitarian Relief Systems under Demand Uncertainty and Road-Facility Vulnerabilities Seminar by Melih Çelik Middle East Technical UniversityAbstract: Disasters may have devastating effects on human life as well as the economy. With its particular proneness to earthquakes, Turkey is no exception for this rule. This study aims to propose a [...]
24/03/2017 @ 13:40 - 14:40 - Hospital Bed Management with Random Patient Length-of-StaySeminar by E. Lerzan Örmeci Koç UniversityAbstract: For the last few decades, it has been very challenging to manage the limited hospital resources due to the constantly increasing demand on health care services. In this talk, we are interested in managing one such resource, namely hospital beds when patients stay [...]
03/03/2017 @ 13:30 - 14:30 - A Computation-Implementation Parallelization Approach to the Computation-Time-Limited Vehicle Routing ProblemSeminar by Bahar Çavdar Middle East Technical UniversityAbstract: Increasing competition in supply chains forces companies into making better and computationally more demanding decisions. This becomes a bigger challenge especially in real-time applications where instances become available just before we need to start implementing the solution. Also, [...]
27/12/2016 @ 13:30 - 14:30 - Methods for Optimization under Uncertainty with Applications in Fleet Management Seminar by İlke Bakır Georgia Institute of TechnologyAbstract: In recent years, large-scale optimization with emphasis on transportation applications has become a particularly exciting field of research, thanks to the rapid technological advancement in transportation equipment and computational tools. Focusing on previously studied problems with this [...]
23/12/2016 @ 13:30 - 14:30 - Stein’s Lemma and Subsampling in Optimization Seminar by Murat A. Erdoğdu Stanford University Abstract: Statistics and optimization have been closely linked since the very outset. This connection have become more essential lately, mainly because of the recent advances in computational resources, the availability of large amount of data, and the consequent growing interest in statistical [...]
21/12/2016 @ 13:30 - 14:30 - Strategic Stable Marriage Seminar byJames Bailey Georgia Institute of Technology, Atlanta, GAAbstract: We study stable marriage where individuals strategically submit private preference information to a publicly known stable marriage algorithm. We prove that no stable marriage algorithm ensures actual stability at every Nash equilibrium when individuals are strategic. More specifically, we show that any rational marriage, [...]
04/11/2016 @ 13:30 - 14:30 - A New Formulation Approach for Vehicle Routing Problem with Backhauls Seminar by Barış Yıldız Department of Industrial Engineering , Bilkent University Abstract: Due to their practical importance and interesting theoretical properties vehicle routing problems (VRP) constitute one of the major research areas in operations research literature. Various formulations and solution algorithms have been proposed to solve [...]
