A New Risk Analysis Approach Based on Linguistic-Valued Lattice Implication Algebra

摘要：

In the framework of the linguistic truthvalued lattice implication algebra, we present a 10-element linguistic-valued lattice implication algebra with linguistic hedges and two antonyms basic words for fuzzy risk analysis. The proposed method better expresses and handles both comparable and incomparable information in risk analysis do-mains. We further discover the operations and special properties of the 10 evaluating linguistic values based on lattice implication algebra. The reasoning and operation are directly acted by the evaluating linguistic values in the risk analysis process. An illustration example shows the proposed approach seems more effective for risk analysis under a fuzzy environment with both comparable and incomparable linguistic values.
