A Method of Hybrid Multiple Attributes Group Decision Making with Risk Considering Decision-Makers' Confidence

A Method of Hybrid Multiple Attributes Group Decision Making with Risk Considering Decision-makers' Confidence

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...

Group decision making method with fuzzy preference of decision makers

A decision is often made in a group and decision makers often utilize fuzzy judgments in attempting to reach an optimal solution. In order to deal with the fuzziness of decision makers' judgments in solutions, this paper proposes a fuzzy group decision-making method for multi-objective decision problems. The method allows group members to express their fuzzy preferences for decision objectives,...

A hybrid group decision making method to analyze the development of third generation biodiesel in Iran

Increasing energy use in the world, limited fossil fuel reserves and environmental issues leads researchers to study about renewable energy resources like biofuels. Biodiesel is a kind of biofuel that can be derived from biomasses like microalgae. These biomasses grow in the southern areas of Iran. So, suitable strategies should be determined to develop biodiesel production from these biomasses...

Interval-Valued Hesitant Fuzzy Method based on Group Decision Analysis for Estimating Weights of Decision Makers

In this paper, a new soft computing group decision method based on the concept of compromise ratio is introduced for determining decision makers (DMs)' weights through the group decision process under uncertainty. In this method, preferences and judgments of the DMs or experts are expressed by linguistic terms for rating the industrial alternatives among selected criteria as well as the relativ...
