Vertex method for computing functions of fuzzy variables. (English) Zbl 0634.94025
The calculation of (fuzzy) values of functions of fuzzy variables is considered. A so-called vertex method is proposed which is based on interval analysis, discretization, extension principle and alfa-cuts of the respective fuzzy sets. The method is easily implementable, and yields normal fuzzy sets, without widening of the resulting function value set.
