In this paper, we present a MCDM model for vendor selection of Telecommunications systems. Decision making in Telecommunications systems (Central) is more important because of their communicational role in organizations. Considering the multiple criteria in the vendor selection of telecommunications systems is a multi-criteria problem. Because these decisions usually are based on the intellectual judgments of managers, Fuzzy logic is used to improve decision making. Literature review and experts opinions used for determining the model indexes and then developed a Fuzzy TOPSIS model with combined weighs. Combined weights are result of integrating various methods such as intellectual judgment of managers, Fuzzy statistical average, modified weight and fuzzy weigh. In this model all numbers are Fuzzy and triangular type. A case study done in Qazvin Islamic Azad University to apply the developed model.
