Choice and decision making are an integral part of the purposeful activities people in all areas public private life. Tasks multi-criteria characterised by fact that alternative decisions evaluated a set criteria concept its outcome coincide. The defining such problems is Pareto optimal (Pareto set). This forms not comparable terms evaluation criteria. choice can be performed only on basis subjective preferences maker. In recent decades, extensions traditional methods to fuzzy environment have been proposed. One well-known approaches TOPSIS method. paper, version this method considered situations where values form numbers.
