free download

The motivation behind this artifact is to inspect the strategy to various multiple attribute group decision making with triangular cubic fuzzy numbers, part of operational laws of triangular cubic fuzzy numbers are connected. We concentrate the group decision making problems in Plant location selection, the process of finding a suitable location for plant of a project has a strong influence on the success of industrial venture with the goal to minimize cost and maximize the use of resources. Thus, plant location selection problem is a multicriteria Abstract Background/Introduction The interval neutrosophic uncertain linguistic variables (INULVs) can be better at handling the uncertainty of the decisionmakers cognition in multi- criteria group decision making (MCGDM) problems. Most MCGDM methods with INULVs are

An interval-valued Pythagorean prioritized operator-based game theoretical framework with its applications in multicriteria group decision making

Multicriteria decision making process explicitly evaluates multiple conflicting criteria in decision making . The conventional decision making approaches assumed that each agent is independent, but the reality is that each agent aims to maximize personal benefit which

Consensus through respect: a model of rational group decision making
free download

Decision making groups frequently face the task of reaching consensus regarding the value of one or more numerical variables. These values represent the final outcome of deliberation (as in the case of an allocation of funds among competing projects), or they In this paper, we study the group decision making problem in which the preference information given by experts takes the form of uncertain additive linguistic preference relations. We define the concept of uncertain additive linguistic preference relation, and The aim of this paper is to extend the VIKOR method for multiple attribute group decision making in interval-valued intuitionistic fuzzy environment, in which all the preference information provided by the decisionmakers is presented as interval-valued intuitionistic

Nowadays, important decisions that have a significant impact either in societies or in organizations are commonly made by a group rather than a single decision maker, which might require more than a majority rule to obtain a real acceptance. Consensus-reaching In general, for multi-criteria group decision making problem, there exist inter-dependent or interactive phenomena among criteria or preference of experts, so that it is not suitable for us to aggregate them by conventional aggregation operators based on additive measures. In Supplier selection and related issues are among the most important decisions in the supply chain management area. Even though there have been so many articles and studies that focused on the mentioned problem in the literature, a few of them considered the major
