drama theory: a problem structuring method in soft or (a practical application: nuclear negotiations analysis between islamic republic of iran and the 5+1 group)

most of the time, groups/communities are involved in negotiations and disputations due to their various interests. they are always trying to pursuit their aspiration to embrace changes and influence on events. although sometimes these groups are not completely opposed to each other and their intention is just to get the desired results, almost always their conditions are in contrast with each other. these conflicts prevent negotiators from approaching desired acceptable solutions. for improving the negotiations, resolving the conflicts and reaching satisfactory decisions, drama theory is applied. this theory is based on game theory. in this paper, iran nuclear talks with 5+1 group will be discussed as an applicable case for drama theory.
