Abstract |
In order to make up for deficiencies of existing studies which neglected fuzziness of information related to emergency early warning in real word, a warning method based on linguistic information was proposed. Firstly, calculation method for basic belief degree of linguistic information under fuzzy frame was provided. Secondly, the information was fused by employing fuzzy evidential reasoning. Thirdly, safety status of warning objects were determined according to final belief degrees of different assessment grades so as to attain early warning purpose. Finally, a numerical example was applied to illustrate feasibility and validity of proposed method. The results show that it can deal with fuzzy warning information of emergencies in real world successfully. © 2020 China Safety Science Journal. All rights reserved. Language: zh |
