Abstract

Selecting the most resilient supplier is a crucial problem for organizations and managers in the supply chain. However, due to the inherited high degree of uncertainty in real-life projects, developing a decision-making framework in a crisp or fuzzy environment may not present accurate or reliable results for the managers. For this reason, it is better to evaluate the potential suppliers in an Interval Type-2 Fuzzy (IT2F) environment for better dealing with this ambiguity. This study developed an improved combined IT2F Best Worst Method (BWM) and IT2F technique for Order Preference by Similarity to Ideal Solution (TOPSIS) model “Atieh Sazan” Co. as a case study, such that the IT2FBWM was employed for obtaining the weight of criteria. The IT2FTOPSIS was utilized for ranking the potential suppliers based on Hamming distance measure. In both phases, the opinions of experts as IT2F linguistic terms were employed for weighting the criteria and obtaining the relative importance of the alternatives in terms of the evaluative criteria. After obtaining the final results, the proposed model was validated by replacing Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) approaches separately instead of BWM for weighting the criteria. After executing both new models, it was found that the final ranking was similar to the final ranking of the proposed model, representing the reliability and accuracy of the obtained results. Moreover, it was concluded that the resilient criteria of “Reorganization” and “Redundancy” are the most determinant measures for selecting the best supplier rather than measures in the Iranian Construction Industry.

Highlights

Chain management (SCM) is one of the most attractive issues among the related experts, according to its role in promoting the efficiency and income of different organizations [1,2]
Because the supplier selection is effective on the whole supply chain, resiliency in this process should always be considered to decrease the vulnerability in the supply chain [8]
Resilient supplier selection is a relatively new topic in supply chain management, which is placed along with sustainable supplier selection and green supplier selection. It is relatively new in comparison with Sustainable Supplier Selection (SSS) and Green Supplier Selection (GSS) [59]

Summary

Introduction

Chain management (SCM) is one of the most attractive issues among the related experts, according to its role in promoting the efficiency and income of different organizations [1,2]. Resilience is the system’s ability to return to its primary state or a better one after emerging disruptions [9]. In this regard, different types of disruptions can emerge in sustainable supply chains because of many reasons in economic, social, and cultural aspects, and so on. Different types of disruptions can emerge in sustainable supply chains because of many reasons in economic, social, and cultural aspects, and so on These disruptions can negatively affect vital factors, including revenue, efficiency, quality, and competitiveness [10]. Designing a resilient supply chain can keep industries away from disruptions [12]
