Ranking function of two LR-fuzzy numbers.

In this paper, we consider the following problems: 1. 'Let à is a fuzzy number and x a real number. Then, what do we say about whether x is greater (smaller) than or equal to �'. 2. 'Let à and $\tilde{B}$ are two fuzzy numbers. Then, what do we say about whether $\tilde{B}$ is greater (smaller) than or equal to �'. [ABSTRACT FROM AUTHOR]
