Today organizational environment has been complicated and in such environment importance of organizational communication are greater. One of strategies to better communication is telecommunication systems in the organization. Telecommunications systems have important role in each organization. Vendor selection of a telecommunications system is a multi-attribute decision making problem. Decision making in real world face with imprecise data and furthermore, because such decisions usually are based on the intellectual judgments of managers, to improve decision making must use fuzzy logic. In this paper, we used literature review and experts opinions for determining the model attributes and then developed a fuzzy TOPSIS model with combined weighs basis final weighs. In this model all numbers are fuzzy and triangular typically. A case study done in Qazvin Islamic Azad University to apply the developed model. Result of this decision mentioned that best systems are purchased. Key Words: Telecommunications Systems (Central), Vendor selection, Fuzzy TOPSIS, Combined Weights.
