Abstract :
We introduce a possibilistic mean value for interval-valued fuzzy numbers as the arithmetic mean of the possibilistic mean values of its upper and lower fuzzy numbers. Furthermore, we suggest a ranking method for interval-valued fuzzy numbers based on their possibilistic mean value and show an application to capital budgeting decisions when the revenues from projects are represented by interval-valued trapezoidal fuzzy numbers.
