With respect to decision-making problems by using probabilities, immediate probabilities and information that can be represented with intuitionistic fuzzy information or interval-valued intuitionistic fuzzy information, some new decision analysis are proposed. Firstly, some operational laws, score function and accuracy function of intuitionistic fuzzy values or interval-valued intuitionistic fuzzy...
We present a new aggregation operator that uses the probability and the weighted average in the same formulation. Moreover, we consider a situation where the information is uncertain and can be represented with fuzzy numbers. We call this new aggregation operator the fuzzy probabilistic weighted average (FPWA) operator. We study some of its main properties. We also study its applicability and we focus...
We present an overview of fuzzy research according to the results found in the ISI Web of knowledge. Among the different ways and particular results to be used, we have selected the most cited articles, the top authors, the top journals, the evolution by years, and the top countries. Note that the results given in the paper are only a general overview because the rankings can be developed in different...
We develop a new approach for dealing with uncertain information in a decision making problem about tourism management. We use a new aggregation operator that uses the uncertain weighted average and the uncertain induced ordered weighted averaging (UIOWA) operator in the same formulation. We study some of the main advantages and properties of the new aggregation called uncertain induced ordered weighted...
The solving processes for decision making problems based on the use of the Dempster-Shafer (D-S) theory can be accomplished in different ways according to the necessities of each single problem. In this contribution we present a decision making scheme based on the D-S defined in a linguistic framework and then, we propose the use of an hybrid averaging operator (2-THA) that use the 2-tuple linguistic...
