Considering the competitive environment between suppliers, the issue of choosing them based on important criteria is very important for decision makers, especially in LARS supply chain which is a combination of sustainable and LARG supply chain. The aim of this paper is to present a multi-objective mathematical model for selecting suppliers based on criteria related to the LARS supply chain concepts. The innovations of the presented model include simultaneous consideration of multiple objectives, multiple periods, multiple products, and master production schedule. The quality of the presented model has been examined on a case study in the country's automotive industry. In this paper, at first, the most important criteria have been extracted from the literatuare ,then finalized by experts in the country's automotive industry (case study in Zamyad Company), and DEMATEL approach has been used to examine the internal relationships of the criteria in each category of criteria. At the second ,the network of criteria is determined, the importance of each criterion relative to the other was determined using a pairwise comparison matrix and considered as input to the SuperDecision software. At last, a mathematical model for optimal supplier selection is presented.Based on the results obtained, the ordering cost has had the greatest impact on the objective function. Also, considering the concept of backlog demand has led to flexibility in production volume and, as a result, reduced overall costs.

In today's markets that industries have faced different risks and disruptions, selecting the appropriate and resilient supplier has become a strategic factor for the success and sustainability of organizations in a turbulent and competitive business environment and has attracted much attention from researchers and practitioners. The natural stone industry is one of the most important industries in Iran. Hence, this study aims to identify and rank the evaluation criteria of resiliency in a real case study of natural stone industry. Gathering the criteria was done based on the previous related literature and in order to confirm the identified criteria, a survey of 10 stone industry experts was conducted using the fuzzy Delphi method. Consequently, 20 criteria was approved. In order to rank the approved criteria, the best-worst method (BWM) was used. The results showed that flexibility, velocity and financial performance are the most important suppliers' resiliency evaluation criteria in the stone industry, respectively.
