Due to economic and managerial disorders, metropolitan peri-urban areas have lost their quality and habitability. Aspects and problems diversity on the one hand, and territorial and functional dispersion on the other hand, have made spatial planning problematic. SDI establishment can improve spatial data management and decrease parallel works, through the creation of metadata, standardization, and development of data-sharing policies in Tehran. However, many internal and external factors have made the implementation of SDI difficult. For this reason, the current research has presented strategies to fulfill the requirements of SDI establishment with a pathological approach and using the SWOT method and the analytical network process method (ANP); consequently, the most important strategies are extrapolated as follows: (1) Research for increasing the efficiency in SDI implementation, (2) Geoportal establishment to improve data management due to peri-urban thematic data diversity and (3) Human resource and new technologies development to reduce the dissipation of financial resources in creating parallel and low-efficient systems.

Population growth and urbanization, increase in number of private vehicles, low-width’s streets and lack of marginal parking spaces, especially in central parts of cities, have brought numerous problems for big and populated cities. Locating mechanized parking lots, which with occupying less area have a high parking capacity, is of the necessities of urban and traffic planning in large cities. The present study aims to identify, to weight and to prioritize effective criteria in locating of mechanized parking with sustainable development approach, and ultimately to prioritize potential sites for the construction of mechanized parking lots in central part of Qom. Therefore, first with regard to principles and components of sustainable development and applicable planning of urban land and transport and traffic planning and also with regard to characteristics of Qom city, three criteria and 16 sub criteria to locate mechanized parking lots have been chosen. The method used in this research for weighting and prioritization of locating criteria and sub criteria is Analytic Network Process (ANP) and fuzzy PROMETHEE. Therefore, after gathering the required data from the paired comparison questionnaire and calculate the total weight of the criteria, priority was given as followed: “environmental” criterion with weight of 0.429 in top priority, “economic” criterion with weight of 0.347 in second priority and “social” criteria with weight of 0.251 was located in third priority. Moreover, the result of ranking potential sites to construct mechanized parking using fuzzy PROMETHEE were identifies as follow: location in Keivanfar street is the first place, location in Sedaqhat alley in the second place and location in ice making factory in the fourth place.

Tax revenue is one of the main government resources. But due to tax evasion and its consequences, the realization of the revenue faces great problem and the reduction results in a deficit of the state budget. The spread of tax evasion phenomenon is because of different factors. One of the tools developed by the legislators is tax sanctions for dealing with violators. The purpose of this study is to evaluate tax sanctions in preventing VAT evasion in Qazvin province. At first, by reviewing previous literature and through 120 questionnaires, experts’ and VAT taxpayers’ opinions were identified then by using Fuzzy DEMATEL techniques and views of 10 experts, the possible relationships, the impact of each relationship and the importance of these factors were determined. The Analytical Network Process (ANP) techniques were used for weighing and ranking the factors. The DEMATEL and ANP power vis-a-vis the first generation of causal-effect relationships are in a way that the number of paired comparisons is greatly reduced and obtaining the opinion of experts becomes simple. The Sampling method is simple random. The results show that tax sanctions are affected by other factors affecting tax evasion reduction but they do not affect any of the indexes and its weights i the lowest compared to other indexes.

This study seeks to identify factors affecting the Iranian economy underdevelopment and the ranking. The method applied, due to the nature of the research, is descriptive. The population of the study was experts in the field of economy. First, by deployment of experts using the Delphi technique, we identified 20 factors affecting underdevelopment in the Iranian economy, in five categories. Then using statistical methods and fuzzy multi-criteria decision-making techniques these factors were rated. The results show of the use of techniques such as multi-criteria decision DEMATEL and ANP. Among the five factors affecting economic underdevelopment, human factors and management have the greatest impact on underdevelopment, and are followed by cultural factors, political factors, social factors, and financial and economic as those with the most impact.

Energy is considered an important factor affecting economic development. Industrial development and increased demand for various types of energy have increased the importance of energy as a whole، and electrical energy. In particular، for the national development strategies and macro policies of nations. This study ranks different power producing stations based upon sustainable development criteria (economic، social، and environmental) through applying a multi- attribute decision making approach of ANP-BOCR. It proceeds to analyze، the ranking of stations through use of super decisions software. The results indicate that combined cycle and nuclear stations have superiority in term of advantages offered. However with reference to costs، combined cycle and hydroelectric stations are most economical. Besides، in term of opportunities offered، renewable stations rank highest. Finally، combined cycle stations have the least risks.
