Generalized approach to modeling negotiations

Based on a concept of pressure which is more general and flexible than the commonly accepted utility approach, this paper develops a general approach for structuring modelling negotiations. The proposed model makes it possible to combine satisficing and optimizing approaches and to discover the best satisficing compromise which may be a dominated or even a non-vertex solution. The set of notions and definitions enables description of different types of negotiations and from different points of view. Two models of simple types of negotiations which are presented in the paper give a basis for further research on more complex types of negotiations.
