Explanation of Theoretical Basics of Analysis of the World Order

International Relations Science has been developed to find an answer to the order puz-zle. The most important subject of processing theories of this field of study is providing an order paradigm between actors of the international system area. This paper aims at determining theories of international relations pertaining to order issue in the post-cold war international system. It seems that the field of international relations is confronted with too many paradigms for an explanation of its subject (order) because of the evolu-tion of its functional framework i.e. international system. Therefore, in reply to reasons of disorders and order issues, some important strategies like balance-driven order, insti-tution-based order, idea-based order, and justice-based order are presented, all of which are described. By the end, it has been tried to present appropriate paradigm indices of order in the current international system.
