摘要
In this work, functions of type-2 fuzzy numbers are analyzed. For the special case of interval type-2 fuzzy numbers, the type-2 membership function of the output variable is calculated using the lower and upper membership functions of the input variables and the vertex method. This procedure is used in an application where the type-2 fuzzy fault currents of an electric distribution system are calculated. The results are shown and the advantages of the approach are discussed.
