%0 Journal Article %T Construction of Functions by Fuzzy Operators %A J¨®zsef Dombi %A J¨®zsef D¨˘niel Dombi %J Acta Polytechnica Hungarica %D 2007 %I ?buda University %X In this paper we present a new approach to compose and decompose functions.This technology is based on pliant concept. We use the proper transformations ofConjunction of Sigmoid function to create an effect. We aggregate the effects to composethe function. This tool is also capable for function decomposition. %K Pliant concept %K Sigmoid %K Conjunction %K Aggregation %K Dombi operator %U http://uni-obuda.hu/journal/Dombi_Dombi_12.pdf
