We propose some similarity measures between two triangular fuzzy numbers (TFNs) based on the vector similarity measures in vector space, which can be used to aggregate the decision information with TFNs. A methodology for multiple criteria group decision-making (MCGDM) problems with triangular fuzzy information is proposed; the criteria values take the form of linguistic values, which can be co...

TOPSIS is one of the major techniques in dealing with multiple criteria decision making (MCDM) problems, and Belief Structure (BS) model and Fuzzy BS model have been used successfully for uncertain MCDM with incompleteness, impreciseness or ignorance. In this paper, the TOPSIS method with Fuzzy BS model is proposed to solve Group Belief MCDM problems. Firstly, the Group Belief MCDM problem is s...

In this paper, a new hybrid fuzzy multiple criteria group decision making (FMCGDM) approach has been proposed for sustainable project selection. First, a comprehensive framework, including economic, social, and environmental effects of an investment, strategic alliance, organizational readiness, and risk of investment has been proposed for sustainable project selection. As the relative importan...

This paper introduces multi-criteria decision making (MCDM) into group decision making to propose a multi-criteria group decision making model for credit risk analysis. This model can not only deal with multi-criteria and complicated practical problems, but also reduce individual subjective preference to support group decision-making. In this model, experts’ opinion is integrated by post-expert...

unsuccessful experiences of two major exhibitions with more than 300 investment projects in mashhad organized with municipalities in 2010 and 2011 and weak implementation of 20 projects, propose the use appropriate methods to identify themes and patterns for components investment projects. this study aims to determine the priorities for investment in the district three of mashhad municipality. ...

We consider multiple criteria decision-making problems where a group of decision-makers wants to find the most preferred solution from a discrete set of alternatives. We develop a method that uses achievement scalarizing functions for charting subsets of reference points that would support a certain alternative to be the most preferred one. The resulting descriptive information is provided to t...
