As express delivery service market in Korea expands rapidly, many domestic companies of various sizes are exposed to fierce competition. They are striving for providing superior service at a competitive price in order to remain competitive. Collaboration creates economies of scale which leads to the reduction of operational cost as well as increase in net profit under a win-win situation. This study proposes a sustainable alliance model, in which the problem is considered of selecting service centers in each merging region with low demand in express courier services. In particular, A co-evolutionary genetic algorithm is developed, which may be implemented under a distributed decision-making scenario assumed in collaboration system. A Shapley value as a methodology for cooperative game theory is also applied for forming coalitions in express delivery services with the equitable allocation to each company. An example problem is performed to verify the appropriateness of the suggested collaboration model.
