Decision making in solving many problems is denominated by traditional techniques which mainly rely on solutions with differential equations. Unfortunately, such analysis is sometimes not very effective in dealing with systems with complex interdependence variables or unclear system boundaries (fuzzy environment).

The concept of fuzzy decision (fuzzy decision) is a reflection of this reality - a reflection that serves as a starting point for the development of decision making that has the ability to model real-world imprecision and uncertainty with Fuzzy logic.
