The paper identifies key factors relating to Iran’s border management from theories and models that related to borders and applies a mathematical analytic hierarchy process (AHP) to scale and level the factors. Results showed that there are 25 factors that could be classified in five sections contributing to effective maritime border management of Iran in Persian Gulf. In terms of the significance of factors, the highest scale is related to political dimension and between the factors the foreign policy of Persian Gulf countries had the highest scale. At second level with less distance to first level, geographical, geopolitical and geostrategic facts have the highest scale and in this dimension the geostrategic position of Persian Gulf had the highest scale. At third, fourth and fifth level, more distance than the first levels, are located respectively players, structural factors and boundary factors.
