Restricted alliance and coalitions formation

Abstract

The task of carrying out humanitarian and peacekeeping missions by a high number of hardly collaborating and vaguely linked nongovernmental organizations is a challenging problem. Collaborators, joined by a common goal, group into parties playing an active role in the mission. In the paper we have considered such groups of collaborators as alliance and coalition. On the account of the fact that some of the group members (agents) representing individual organizations may disagree to cooperate (share information and resources) with all the other agents but only with a selected number of them, we introduced the specific type of alliance called "restricted alliance". The paper focuses on the problem of coalition formation (coalition structure) with the agents of restricted alliance. The main attention is paid to the issues of agents' activities at the stage of coalition structuring.
