This proceedings volume presents recent theoretical and practical advances in operational research (OR). The papers focus
on a number of key areas including combinatorial optimization, integer programming, heuristics, and mathematical programming.
In addition, this volume highlights OR applications in different areas such as financial decision making, marketing, e-business,
project management, scheduling, traffic and transportation. The chapters are based on papers presented at the 13th Balkan
Conference on Operations Research (BALCOR). BALCOR is an established biennial conference. The selected papers promote international
collaboration among researchers and practitioners, with a particular focus on the Balkan countries.
