The purpose of this study was to present a model for analyzing and evaluating suppliers in the Imam Petrochemical Procurement Department based on hierarchical analysis with non-linear (gray) data. The statistical population of this study consisted of an expert group of 20 managers and senior staff of Bandar Imam Petrochemical Procurement Department. To select these individuals, we tried to provide the most knowledgeable people in the field after preparing a complete list, through non-random "judgmental" sampling. Research topic selected and involved in the research process. The main data collection tool in this study was questionnaires designed for different purposes and distributed to the target population after obtaining the approval of the respected supervisor. After distributing and collecting the data, the necessary analyzes were performed through SPSS, Expert Chase and Excel software. In this process, analyzes such as t-test and hierarchical gray analysis were performed. Finally, the research results identified 4 main criteria (supplier criterion, product performance criterion, service performance criterion, cost criterion) and 27 factors were identified and their ranking was determined. It should be noted that this research is of practical purpose, in terms of survey approach and exploratory studies.
