Comparative Analysis of Multi-criteria Evaluation of Sustainable Supplier Selection Problem Based on Hesitant Fuzzy Linguistic Term Sets
نویسنده
چکیده
The sustainable supplier selection process requires consideration of multi-criteria evaluations. In recent years, to prevent the hesitation of different linguistic expressions by the decision makers, and to help the selection of the best one as the solution of different alternatives, researchers have been using several methods such as hesitant fuzzy linguistic term sets (HFLTS), hesitant fuzzy linguistic (HFL) VIKOR, HFL TOPSIS, and HFL TODIM. In this paper, the sustainable supplier selection process based on Triple Bottom Line (TBL) approach (economic, environmental, and social dimensions) and the comparative analysis of multi-criteria decision-making problem are evaluated using these different methods. Firstly, the decision-making methodologies for the selection of best alternative are described to determine compromise solutions for a problem with conflicting criteria. Then, an illustrative example from the retail market is presented to compare HFLTS, HFL VIKOR, HFL TOPSIS, and HFL TODIM methods for the supplier selection problem with hesitate fuzzy linguistic information. Consequently, similar results have been obtained despite the differences in calculation algorithms of decision methodologies.

Selecting the most suitable alternative under uncertainty is considered as a critical decision-making problem that affects the success of organizations. In the selection process, there are a number of assessment criteria, considered by a group of decision makers, which often could be established in a multi-level hierarchy structure. The aim of this paper is to introduce a new hierarchical multi...

Supplier selection can be considered as a complicated multi criteria decision-making problem.In this paper the problem of supplier selection is studied in the presence of conflicting evaluations and insufficient information about the criteria and different attitudes of decision makers towards the risk. Most of fuzzy approaches used in multi-criteria group decision making (MCGDM) are non-intuiti...
