Cities are the most important targets of an enemy invasion because of the high population density and the place of capital accumulation. Accordingly, this study seeks to rank the vulnerability of the five regions of Urmia city against the dangers of unexpected events and war based on passive defense principles by investigating and identifying effective indicators. This research, based on its purpose, is an applied research and according to the method of work, has an analytical nature. In this study, after studying and analyzing the related documents and resources of passive defense, 14 indicators that are related to some principles of passive defense including principles of dispersal, hardening and localization were selected and then hierarchical analysis process method was used for giving weight to the indices. For performing spatial analyses, index data layers were first digitized and edited in GIS software and by converting data layers into raster and classifying them, the calculated coefficient of significance (via hierarchical analysis method) was multiplied in each index and by using the weighted sum of the indices, the vulnerability was measured in the five districts of Urmia city. In the final step, the vulnerability of the five regions of Urmia city was ranked according to the TOPSIS model. The results indicate that the vulnerability of the five regions of Urmia city are from top to bottom, respectively, regions five, one, three, four and two and also in most of the cases, they are associated with weaknesses in the principle of dispersal, hardening and localization.

Economic and oil sanctions against the I.R.Iran have played an important role in the stagnation of Iran's oil industry in the last 10 years, especially after the sanctions were intensified in July 2012. Iran's ability to produce oil declined and its oil exports were decreased by 50 percent over this period. But, many analysts believe that the sanctions were not the only factor that affected Iran's petroleum industry and the problem of mismanagement among high-level executives and high-level managers in oil industry has played an important role in its growing stagnation. Some other experts emphasize the role of fluctuations in the world oil market. However, there is no accurate figures about the effects of each factors because of the existence of several variables but, this article by using Analytical Hierarchy Process (AHP) method, explore the weight of each effective factor. The calculations based on this method show that from 2004 to 2014 mismanagement in oil industry was responsible up to 35/5 percent, mismanagement in high-level executives was responsible up to 33/5 percent and the economic sanctions responsible only up to 31 percent in the stagnation of Iran's oil industry. Based on the statistical data resulting from this research, we can study influential factors on oil industry development with a new attitude and put emphasis on the neccessity of removing existing obstacles and implementing institutional and structrual reforms to achieve the goal of oil industry development and eventually, sustainable development on the basis of developing comprenensive economic institutions.
