Optimization and Operations Research is a component of Encyclopedia of Mathematical Sciences in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias.
The Theme on Optimization and Operations Research is organized into six different topics which represent the main scientific areas of the theme: 1. Fundamentals of Operations Research; 2. Advanced Deterministic Operations Research; 3. Optimization in Infinite Dimensions; 4. Game Theory; 5. Stochastic Operations Research; 6. Decision Analysis, which are then expanded into multiple subtopics, each as a chapter. These four volumes are aimed at the following five major target audiences: University and College students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.
Ulrich Derigs is Director of the Department of Information Systems and Operations Research (WINFORS) at the University of Cologne, Germany. He received a Master’s degree (1975) and a Doctoral degree (1979) in Mathematics and a Doctoral degree (1981) in Economics from the University of Cologne. In 1985 he completed his habilitation at the University of Bonn. He was Assistant Professor at the Mathematical Institute (1976 to 1979) and at the Seminar for Industrial Engineering (1979 to 1981) at the University of Cologne. From 1981 to 1985 he was Assistant Professor at the Institute for Econometrics and Operations Research at the University of Bonn and member of a Sonderforschungsbereich (DFG). From 1985 to 1990 he was Professor of Information Systems and Operations Research at the University of Bayreuth, and since 1990 he has been Professor at the University of Cologne. He has done extensive research in combinatorial optimization with an emphasis on the design, analysis, and evaluation of efficient algorithms and industrial applications. Today his interest lies in the interface between Operations Research and information systems. His focus is the design and implementation of model-based decision support concepts and systems in different application areas such as routing and scheduling, production planning, logistics, finance, and telecommunication.
Ulrich Derigs is on the editorial board of several journals. From 1988 to 1992 he was editor in chief of OR-Spektrum, the journal of DGOR, the German OR society. From 1992 to 1998 he was a member of the board of DGOR and from 1996 to 1998 President of the DGOR.
