Radial fuzzy systems are fuzzy systems exhibiting the radial property in antecedents of their rules. A fuzzy system has nominal consequents if its output is defined on a finite unordered set of possible actions. The question of coherence is the question of under which conditions we are assured that regardless the input to the system is, an output of the system exists, i.e., the output is non-empty. In other words, a fuzzy system is coherent if it has no contradictory rules in its rule base. In the paper we state sufficient conditions for a radial I-FS with nominal consequents to be coherent.
