Preface
This volume contains a selection of refereed papers referring to lectures presentedat the symposium "International Conference on Operations Research (OR2010) –Mastering Complexity" held at Universität der Bundeswehr München, September1–3, 2010. This international conference took place under the auspices of the Ger-man Operations Research Society (GOR). It was organized for the first time in part-nership with the Italian Operational Research Society (AIRO) which was responsi-ble for the organizations of three topics.
The symposium had about 750 participants from more than 48 countries all over theworld; more than 30 colleagues came from Italy and 127 researchers registered asPhD-candidate; this category was offered successfully for the first time. The confer-ence attracted academics and practitioners working in various fields of OperationsResearch and provided them with the most recent advances in Operations Researchand related areas to the general topic "Mastering Complexity".
Complexity is a natural component of the globalization process: Financial markets,traffic systems, network topologies, energy resource management and so forth areall characterized by complex behavior and economic interdependencies. OperationsResearch is one of the key instruments to model, simulate and analyze such systems,and to answer questions concerning not only efficiency but also safety & security. Infact, gaining optimal solutions, suitable heuristics and efficient procedures for theseapplications are some of the challenges which were discussed at the internationalOR2010 and are documented in that volume.
At the conference, 439 regular talks, 2 plenary keynotes, 15 invited semi-plenarytalks and 7 invited talks by award recipients were given. Out of those contributionsaccepted for presentation at the conference, 171 extended abstracts were submittedfor the post-proceedings, of which 104 were finally accepted –after a thorough peer-reviewing process– for publication in the present volume. Due to a limited numberof pages available for the proceedings volume, the length of each article had to berestricted.

Preface
We would like to thank the GOR-board for the abundant collaboration, which wealways found to be helpful and fruitful. We are grateful to all the anonymous re-viewers, who were asked to review one or more submitted papers. Many thanks toour Italian colleagues Grazia Speranza, Paola Zuddas and Renato de Leone for theircooperation and enormous efforts. We have to say special thanks to Zafer-KorcanGörgülü who invested a lot of time in preparing this LATEX-document and optimizingthe layout process in an excellent manner.
Finally, we would like to thank Dr. Werner A. Müller and Christian Rauscher fromSpringer-Verlag for their support in publishing this proceedings volume.
