Many of today’s systems are characterized by a network structure and evaluation of alternatives is based on multiple criteria. Network systems contain both positive and negative feedbacks. In the paper, a hybrid procedure is proposed for operation in network environment. The procedure is based on a combination of DEMATEL, ANP, and PROMETHEE approaches. DEMATEL is a comprehensive method for building and analyzing a structural model involving causal relationships between complex factors. For the network seems to be very appropriate Analytic Network Process (ANP) approach. The ANP makes possible to deal systematically with all kinds of dependence and feedback in the system. PROMETHEE methods are methods for multi-criteria evaluation of alternatives, based on preference relations between alternatives, which may be expressed as a network. These methods have specific advantages in analyzing and evaluating network systems. The combination of these approaches gives a powerful instrument for analyzing network systems by multiple criteria.
