The bipolar nature of group decision and negotiation processes makes them difficult to analyze. On the one hand, a multitude of behavioral factors needs to be taken into consideration when examining the specificity of interaction between all stakeholders and parties involved. On the other, the formal issues related to the problem structuring and solving should be examined to assure that the compromising solution would be efficient and satisfying for all stakeholders. To provide a comprehensive support to the negotiating parties an integrated approach that takes into account both behavioral and formal issues should be applied. It requires combining the recent developments from such fields as sociology, psychology, economics, management science (decision making, operations research) and computer science. However, when the economic aspects of negotiation or group work are becoming more important to the stakeholders (such as the costs and profitability of the solutions implemented or their impact on the society) a bigger focus is put on improving the decision making mechanisms and developing the formal concepts that lead to best possible and efficient compromises.
