The purpose of this paper is to propose an improved hesitation fuzzy multi-attribute decision-making method realize green supply chain member selection under innovation vision. uses sets express decision information makers, takes capability as the evaluation perspective, and selects input, synergy subjects in chain, output capability, institutional enterprises sustainability indexes evaluate en...

Because of the complexity of decision-making environment, the uncertainty of fuzziness and the uncertainty of grey maybe coexist in the problems of multi-attribute group decision making. In this paper, we study the problems of multi-attribute group decision making with hybrid grey attribute data (the precise values, interval numbers and linguistic fuzzy variables coexist, and each attribute val...

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 ...

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...

Extended hesitant fuzzy sets (EHFSs), which allow the membership degree of an element to a set represented by several possible value-groups, can be considered as a powerful tool to express uncertain information in the process of group decision making. Therefore, we derive some correlation coefficients between EHFSs, which contain two cases, the correlation coefficients taking into account the l...
