Globalization, intensification of governmental and non-governmental organization & apos; s provisions and squeeze and the demand of clients about concerning environmental affairs have motivated many organizations to start considering Green Supply Chain management in order to facilitate environmental and economic functions. Administration of green supply chain management unifies the management of supply chain with environment requirements during the functioning of levels of supply chain. This paper aims to identify green supply change management & apos; s factors in order to facilitate implementation of green supply chain management in rail industry. Thus, the effective factors of green supply chain management establishment are extracted and the method of interactions between sub-scales is studied by DEMATEL technique. The result specifies that reduction of production loss sub-scale is the most effective factor on other agents. In addition, the effective elements peered out by fuzzy TOPSIS that the scale of loss management stands on the first ranking and improvement of production process and interior environment management scales stand on the second and the third level and other scales follow them.

Today, development of economic activity and employment is known as an effective strategy for economical and social development of the countries. Entrepreneurship in Iran is also as the most executive and practical strategy to exit the economical and social deadlock and problems. However, entrepreneurship development needs identifying and removing existed obstacles and problems. There are a lot of researches about obstacles and restrictions on entrepreneurship but, to the best of our knowledge, there is no research to identify vital factors and degree of their effect on the network of factors. In this paper using DEMATEL technique, the entrepreneurial barriers in the industry of Iran are categorized in 2 groups of cause and effect. We also use fuzzy concept to handle any ambiguity on the feedbacks gathered from decision makers. To achieve this purpose, at first using views of professors and active managers in the field of entrepreneurial and also related books and using Delphi technique, 9 vital factors are identified and they are analyzed in two groups of internal and external obstacles in the industrial sector of Iran. The research chooses 100 most active companies in one of the industrial poles of Iran for the proposed study of this paper. Furthermore, questionnaires are distributed among the top managers of these companies, to analyze the barriers in entrepreneurship in the industry. The results show that two factors of "kind of management" and "organizational structure" are the most important factors. In addition, “legal obstacles" and" optimum use of financial resources” are at the highest degree of impression on business units.

One of the main challenges in Stock Market is to choose an appropriate combinations of various assets. The aim of this study is to propose a hybrid method, which is able to survey one problem with some criteria that it is very good for investment problem. In this study, we use a hybrid multiple criteria decision-making (MCDM) model, which shows the dependent relationships among criteria with DEMATEL method to build a relations-structure among criteria. We then use Analytical Network Process (ANP) to determine the relative weights of each criterion with dependence and feedback, and the VIKOR method is implemented to rank and select the best alternatives for investment. This study is in stock exchange in Iran to select the best stocks and the data are gathered through the years (2006-2010). There are a lot of methods to rank and select of firms that most of the methods just do one, ranking or selecting; but the used method in this study not only ranks the firms but also determines which firms (stocks) are best for investment, so that in this study 2 of 50 firms are proposed for investment.

This paper identifies and analyzes barriers of customer relationship management (CRM) implementation in SMEs. Hence, based on a comprehensive review of the literature and gathering the viewpoint of experts, the influencing barriers are identified. In order to analyze the identified barriers, DEMATEL methodology is applied and a causal model of the relationships between barriers is developed. Furthermore, based on the DEMATEL results the barriers are also categorized into two groups of driver and dependent. The results of study show that inadequate budget, organization culture, obligation of major management to CRM and inadequate access to modern technical knowledge are among effective impediments and play important role in successful establishment of customer relationship management system.

Agile supply chain plays an important role on having efficient production planning. There are different factors affecting the efficiency of a supply chain and the attempt of this paper is to find the most important elements in agile supply chain. The proposed model of this paper gathers decision makers & apos; opinions and based on DEMATEL technique determines the most important items. The preliminary results of this survey indicate that we could divide the factors into four groups and two elements including automation and utilization of technical tools of relations and information play the most important roles among other factors.

Measuring the performance of a supply chain is normally of a function of various parameters. Such a problem often involves in a multiple criteria decision making (MCMD) problem where different criteria need to be defined and calculated, properly. During the past two decades, Analytical hierarchy procedure (AHP) and DEMATEL have been some of the most popular MCDM approaches for prioritizing various attributes. The study of this paper uses a new methodology which is a combination of AHP and DEMATEL to rank various parameters affecting the performance of the supply chain. The DEMATEL is used for understanding the relationship between comparison metrics and AHP is used for the integration to provide a value for the overall performance
