The cloud model, which can implement uncertain transformation between a qualitative concept and its quantitative instantiations, has attracted great attention in multicriteria decision-making problems with linguistic information. This paper proposes some operations and a possibility degree of trapezium clouds, as well as several new aggregation operators: the trapezium cloud weighted arithmetic averaging...
It has been an increasing trend to develop multicriteria decision-making models with imprecise, uncertain, or vague decision data. An effective way to express a decision maker's (DM's) uncertain preference information is the use of interval-valued intuitionistic preference relations. In this paper, the concept of multiplicative consistent interval-valued intuitionistic preference relations is defined...
In order to enhance the veracity of situation and threat assessment for warship formation in air deference, the paper proposes an intuitionistic fuzzy likelihood method base on multi-attribute optimization. Uncertainty information under intuitionistic fuzzy environment can be expressed and fused in the proposed method and model. The key of the model is an interface provided to commander to intervene...
Riskless interest rate and volatility are two important variables in option pricing model, but are hard to be estimated precisely. The concept of fuzziness is used to describe these variables in this paper. We apply fuzzy set theory to the American put option valuation and extend the fuzzy option pricing model by introducing riskless interest rate and volatility as two trapezoidal fuzzy numbers. The...
