ABSTRACT = {Many practical applications, under the definitive evolutionary state of the nature, the consequences of 
the decisions, mental states of a decision maker are required. Thus, the need is for a new concept in the 
analysis of decision-making. Zadeh has introduced this concept as the Z-number. Because the concept 
is relatively new, Z-number in fuzzy sets, hence, its basic theoretical aspects are yet undetermined. This 
paper presents a method for ranking Z-numbers. Hence, we propose a new method for ranking fuzzy 
numbers based on that of hyperbolic tangent function and convex combination. Then, using the same 
technique we propose a method for ranking Z-numbers.},
