Today, due to the importance and expansion of the use of information technology, many organizations are witnessing problems and inconsistencies regarding the non-fulfillment of business needs due to the high volume of investment in information technology. One of the reasons for this discrepancy is the lack of alignment between the IT strategy and the business strategy, and therefore the lack of effective implementation of information technology governance. Therefore, the most important goal of the research is to provide a model for identifying and ranking the factors affecting IT governance. For this purpose, it has been used from the combined approach of fuzzy DEMATEL and fuzzy ANP .In this study, the data of 20 experts in the field of information technology are collected through a questionnaire. Therefore,The research method is  descriptive survey based on the nature and data collection and in terms of purpose, it is a practical development. In order to achieve the goals and answer the research questions, this research has been done in three main phases. In the first stage, by reviewing the literature and evaluating the results of studies, Provides a context for the comprehensive identification and extraction of factors and sub-factors affecting IT governance and their classification. In the following,  for the screening the identified variables, fuzzy Delphi technique was been used and with the opinion of experts, the classification of 21 key sub-factors among the 7 main factors has been confirmed. In the second step, internal relationships between the main factors are calculated using fuzzy DEMATEL method and the location of the network is plotted. Finally combined DEMATEL and fuzzy ANP and fuzzy ANP method has been used to weigh the factors and rank them. One of the most important result of the current research is to identify the causes and prioritize the effective factors in implementing of information technology governance in organizations. These priorities indicate that, among other factors, the position of information technology in organizational structure in the weight of networks analysis has the first priority. Too, By DEMATEL method .The IT strategy factor with the highest output vector has been identified as the most influential factor and the support and skills of senior IT managers with the highest total output and input vector have been identified as the most interactive factor

This study aimed to identify and categorize factors in successful implementation of knowledge management using fuzzy Dematel in Saraamadan Elmo-Fanavari Salmanian Fars Company.
This study is an applied research in terms of objective and descriptive-survey in terms of data collection. The population of this study consists of 15 experts from Saraamadan Elmo-Fanavari Salmanian Fars Company. The data collected by 2 questionnaires. The first questionnaire was used to identify the most important success factors of knowledge management the proposed factors. The second questionnaire was to compare the priority of the factors identified by the first questionnaire.
Findings: Taking 11 influential factors for the successful implementation of knowledge management into consideration, based on the respondents’ point of view, culture of people, motivation and communication were identified as the most important cause factors, and information technology was introduced as the most important effect factor.
The most important step in the successful implementation of knowledge management in organizations is to identify the most influential factors for implementation of knowledge management. Results indicate that, culture and people, motivation and communication can be considered as the most important cause factors for the successful implementation of the company's knowledge management system.

Due to different effects of ICT on varied aspects of performing the duties in organizations, governments have been intending to use ICT in the recent years very dramatically. The significant issue to which we should pay attention is the using of ICT without directing attention towards the mutual effects of different ICT domains shall be resulted in malfunction and inefficiency of organizations in carrying out their tasks. Therefore, the present research tried to develop a systematic structure in ICT domain and analyze the various ICT domains in order to identify the penetrating and penetrated factors (cause and effect). In doing so, at the present research firstly by the usage of other researcher's results and achievements, it was attempted to specify the different ICT domains including objectives, obstacles, drivers, team dynamics and organizational support and then another elements so-called ICT effectiveness was added in order to study the effect of above-mentioned factors on ICT effectiveness. Then, standard fuzzy DEMATEL technique questionnaire was distributed among 35 persons of experts working in ICT and IT fields to gather required information and data. After gathering required data and information, they were analyzed through DEMATEL techniques in fuzzy states, respectively. The results obtained from the DEMATEL technique in fuzzy state reveal that in ICT domain, the objectives were determined as the most penetrating elements into other elements of ICT domain and the drivers were the most penetrable element in ICT domain too.
