| Abstract: |
| We introduce the influence factor when a fuzzy set is situated in the different position based on decision makers' risk preference.Then we get a new formula of the degree of fuzziness for fuzzy sets based on the relative close degree of fuzzy set and the most fuzzy set. Some numerical examples are displayed to verify the validity and resolution of the proposed new fuzzy degree, which can effectively compare the fuzziness of fuzzy sets. |
