Abstract
A decision-making process requires a prior definition and fulfilment of certain factors, especially when it refers to complex fields such as supply chain management. One of the most important items in the initial stage of a supply chain, which strongly influences its further flow, is making a decision on the most suitable supplier. In this paper, a model for evaluation and supplier selection has been proposed, which has been considered in more than ten different production areas. The model consists of twenty quantitative and qualitative criteria, which are reduced to a total of nine by the application of the fuzzy AHP and the assessment of managers in production companies. The verification of the model has been presented throughout a selection of suppliers in a company for the production of plastic bags and foils, where the Fuzzy Analytic Hierarchy Process (Fuzzy AHP) method has been used to determine the significance of the criteria, and the Fuzzy Evaluation based on Distance from Average Solution (Fuzzy EDAS) to evaluate and select suppliers. The obtained results have been considered throughout a sensitivity analysis in which a total of 15 different scenarios have been formed and where the stability of the model has been determined, since the supplier one is the best solution in all the cases.
Highlights
According to Jafarnejad and Salimi (2013), the success of an entire supply chain largely depends on the selection of suppliers, while authors of the paper (Singh et al 2012) point out that the process of supplier selection is one of the most significant factors, which has a direct impact on an organization’s performance

The subsystem can effectively perform tasks related to the supply of a company, if it chooses a supplier or suppliers that can meet the requirements, which are put in the supply subsystem and refer to the quality, quantity, price, delivery deadlines and other deadlines, reliability, flexibility, as well as other goals that need to be fulfilled satisfying other criteria, which are presented in the rest of the paper and which are determined by a literature review and research in the economic system
Summary
According to Jafarnejad and Salimi (2013), the success of an entire supply chain largely depends on the selection of suppliers, while authors of the paper (Singh et al 2012) point out that the process of supplier selection is one of the most significant factors, which has a direct impact on an organization’s performance. The subsystem can effectively perform tasks related to the supply of a company, if it chooses a supplier or suppliers (a small number) that can meet the requirements, which are put in the supply subsystem and refer to the quality, quantity, price, delivery deadlines and other deadlines, reliability, flexibility, as well as other goals that need to be fulfilled satisfying other criteria, which are presented in the rest of the paper and which are determined by a literature review and research in the economic system. The search for suppliers that fulfil the previously written is a permanent and primary task For this purpose it is necessary to continuously collect and process data on suppliers, establish and maintain adequate relations with them, and to develop and apply methods for evaluation and ranking of potential suppliers
