If [ a , b ] does not exist (i.e., [ a , b ] is an empty set), we say this fuzzy sample does not

have fuzzy mode.

Example 3.1. Suppose eight voters are asked to choose a chairman from four
candidates. Table 1 is the result from the votes with two different types of voting:
traditional response versus fuzzy response.

From the traditional voting, we can find that there are three persons who vote B.
Hence, the mode of the votes is B. However, from the fuzzy response, B only gets a
