Multiple attribute decision-making theory under uncertainty is an important part of decision making theory. In this paper, by using optimal plan, the optimization weight model is established. Then, based on formulas of possibility degree, a new attribute decision making approach is proposed to study multi-criteria decision making problems under uncertainty in which criteria values are interval ...

With respect to different confidence on evaluation result from different decision-makers to the hybrid multi-attribute with risk, an approach to group decisionmaking based on prospect theory and projection theory is proposed. Firstly, a tuple is established to record the evaluation result and the hybrid decision information. Then the element of the tuple is changed into a single triangular fuzz...

The article presents an approach to the development of multi-attribute decision making model that is based on DEX, an expert system shell for multi-attribute decision support. We demonstrate the applicability and flexibility of the approach presenting application of DEX in e-learning: assessment and evaluation of Learning Management Systems (LMS) where several conflicting objectives, like envir...

The extended TOPSIS method is proposed to solve multi-attribute group decision-making problems which the attribute values take the form of interval grey linguistic variables and attribute weight is unknown. To begin with, the relative concepts of interval grey linguistic variables are defined; the operation rules, the properties, and the distance between the two interval grey linguistic variabl...

Interval type-2 fuzzy sets, each of which is characterized by the footprint of uncertainty, are a very useful means to depict the linguistic information in the process of decision making. In this article, we investigate the group decision making problems in which all the linguistic information provided by the decision makers is expressed as interval type-2 fuzzy decision matrices where each of ...

Interval-valued intuitionistic fuzzy number uses membership degree and non-member ship degree to express a decision-maker’s hesitation, which make decision-maker express his/her opinion in uncertainty decision-making environment easily. The comparison between some intervalvalued intuitionistic fuzzy numbers can not be undertaken because of its limitation. In application such as weak consistency...
