摘要：In line with the expansion of Information Technology (IT) and increasing of its usages, especially with universality of internet, experts in Iran's customs– with regard to their natural duty in commercial transactions with international and universal societies - have also tried their best to exploit and use these new technologies. Therefore, since June 1990,Iran's custom through cooperation with United Nations Conference on Trade and Development (UNCTAD), United Nations Conference on Development Program (UNDP), and World Customs Organization (WCO), had tried to establish this system in Iran. In 1377 Hegira, by recognizing capabilities and attributes of ASYCUDA in equalizing and facilitating customs services, and increasing the efficacy of Iran's customs, it is established in west Tehran customs and import section. ASYCUDA is a system for automatic processing of customs data which is a plan called NEGAR (acronym for automated system for customs data in Persian) in Iran. Then other parts like export, temporary admission, and temporary exportation, were performed in this customs as other sub plans of ASYCUDA. The aim of this research is to recognize obstacles in effective executing of ASYCUDA for increasing the speed of goods release, optimal exploitation of storehouses, better use of human force, developing usage culture for mechanized systems, gaining more income, and presenting in time, rapid, and exact statistics for foreign trades. This project is applicative by aim, but naturally, it is a surveying-descriptive project. We use some measures like frequency distribution, percentage, measures of central tendency, and measures of distribution, and statistical graphs in descriptive analysis. In inferential analysis, first by means of Kolmogrof Smirnov's test, we examined the normality of data, and then by using T test we compare observed (practical) averages with theoretical one to decide about rejection or approval of each hypothesis individually. Finally, by using one-way analysis of variance, we compare the averages of four responding groups (Zanjan and Qazvin staffs, and clients of both of them) for every variable, and then with regard to research hypotheses, we compare these groups' opinions. According to the obtained results, it is identified that in Zanjan and Qazvin customs the establishment of ASYCUDA has increased the speed of customs performance. All people have enjoyed from cost reduction in customs affair, and this enjoyment has been equal among all of them. Moreover, the establishment of ASYCUDA has increased the accuracy of releasing goods and as a result clients' satisfaction has increased
