Abstract

The processes of identifying the best suppliers for a new product or service or even to evaluate the performance of an existing supplier are essential tasks in managing the supply chain, in order to enable that the collaborative process occurs in an efficient manner. The supplier selection problem (SSP) fits the multicriteria context due to involve several qualitative and quantitative criteria in the decision making process. So, the main objective of this research is to propose a model of multiple criteria decision aid for suppliers sorting in levels of collaboration in supply chain management, using ELECTRE TRI method. Several studies have approached the supplier selection problem in multicriteria context. Most of these studies address the choice and ranking problems and specific methods are proposed for this purpose. However, the sorting problem is not much explored, and in addition, there are few studies that specifically address the subject of collaboration with suppliers considering multicriteria context. Whereas in most cases, in several business segments, companies have at their base, suppliers with different features and degrees of performance, it becomes necessary to decide at what level to collaborate with each type of supplier. Thus, using the proposed model makes it possible to manage suppliers, considering their differentiation in terms of performance, sorting them into appropriate levels of collaboration in order to facilitate the adoption of different strategies with each category. Moreover, with the use of this model, it is possible that the decision in this context occurs in a systematic manner and, considering the repetitive nature of this problem, the proposed model constitutes a useful tool for decision aid. This tool can be used periodically in accordance with the needs of the decision maker in order to provide feedback of the evaluation to suppliers, monitoring the performance in the defined criteria set and, reviewing the strategy adopted if necessary.
