Linguistic modeling of complex irregular systems constitutes the heart of many control and decision making systems, and fuzzy logic represents one of the most effective algorithms to build such linguistic models. In this paper, a linguistic (qualitative) modeling approach is proposed. The approach combines the merits of the fuzzy logic theory, neural networks, and genetic algorithms (GA s). The proposed model is presented in a fuzzy-neural network (FNN) form which can handle both quantitative (numerical) and qualitative (linguistic) knowledge. The learning algorithm of a FNN is composed of three phases. The first phase is used to find the initial membership functions of the fuzzy model. In the second phase, a new algorithm is developed and used to extract the linguistic - fuzzy rules. In the third phase, a multiresolutional dynamic genetic algorithm (MRD - GA) is proposed and used for optimized tuning of membership functions of the proposed model. Two well - known benchmarks are used to evaluate the performance of the proposed modeling approach, and compare it with other modeling approaches.
