Speech Title: The Problem of Covering Solids by Spheres of Different Diameters

Abstract: We propose a mathematical programming formulation (Mixed-Integer Nonlinear Programming) for the problem of covering a solid by a finite number of spheres of different radii. We use this approach to model and study a complex sphere covering problem occurring in the configuration of a gamma ray machine radiotherapy equipment unit. We illustrate some results.

Date and Time: Thursday, September 26, 17:15-18:00

Speech Title: Optimization and Modeling in Energy Systems

Abstract: Energy systems are undeniably considered as one of the most important infrastructures in the world. Energy plays a dominant role in the economy and security of each country. In this lecture, we are going to consider several difficult problems in energy networks, such as hydro-thermal scheduling modeling, electricity network expansion, liquefied natural gas and blackout detection in the smart grid.

Date and Time: Thursday, September 26, 14:15-15:00


Roman Slowinski 

Professor and Founding Head of the Laboratory of Intelligent Decision Support Systems within the Institute of Computing Science, PoznaƄ University of Technology, Poland.
Coordinating Editor of the European Journal of Operational Research (EJOR).

Speech Title: How the European Journal of Operational Research (EJOR) reflects
the evolution of Operational Research?

Abstract: The editor of EJOR will answer the question posed in the title, giving some characteristics of the journal, and explaining the approach of its editors to evaluation and selection of articles. Topics of Operational Research which recently raised the highest interest will also be pointed out. Some quantitative measures of the journal quality will be presented, along with the EJOR-R-index that has been proposed and used by the editors of EJOR to award 25 best reviewers each year. The last part of the presentation will be devoted to some advices addressed to young researchers on how to write articles about Operational Research.

Date and Time: Friday, September 27, 11:00-11:45


Alexis Tsoukiàs

CNRS (Centre National de laRechercheScientifique) research director at LAMSADE, Université Paris Dauphine. Former President of the Association of European OR Societies (EURO).

Speech Title: What is a Decision Problem?

Abstract: The talk introduces a general framework through which the whole potential set of decision problems can be described. The aim of the framework is to show that only a finite number of primitive characteristics describe a decision problem, thus reducing it to a finite number of combinations. In the talk we present in some details some of these characteristics, particularly emphasising the problem statement dimension. We also provide a number of simple examples in order to show how this framework helps in categorising current decision problems, in reformulating decision problems and in constructing formal arguments for the decision aiding process.
