Transfer of technology as an inevitable necessity has been interested by scientific directors and executive directors in the past two decades. Obstacles facing this transition in modern countries (developed) in the countries such as Iran is considered significantly. This study is a descriptive survey, and applied in term of purpose. The purpose of this study is to identify and rank the barriers to transfer technology in Iran.Mentioned study uses literature research and expert opinions gathered through interviews and questionnaires, to identify high-impact barriers and has prioritized the major obstacles to transfer technology through the use of hierarchical analysis. The results show that technical, human, organizational information barriers were the most important barriers to transfer technology in Iran and technical barriers, in the infrastructure; in human barrier, managerial skills, the obstacle information, cost information and ultimately organizational barriers, have created the challenges.

In recent years, the supply chain has become a subject of interest for the managers and captains of industry and the life and death of the business organizations and corporation depend on the activity of intertwined chains. Beyond this definition, by adding the term Green, chain management refers to green procurement, green production, green distribution, green supply and inverse logistic. The main approach of this paper is designing and offering a mathematical model for designing the green supply chain networks, which three-level planning is developed, which is aimed in optimizing two contradictory goals and has problem conflicts including 1-minimization of costs, and 2-minimization of environmental pollutants. The problem is expressed as the longitudinal programming of integer numbers. Results show applicability and practicality of this model.
