The research method of the present study was qualitative. In order to collect data, it was attempted to review related domestic and foreign researches. In the following, Dimtel and ISM questionnaires, gray hierarchy analysis questionnaires and gray relationship analysis questionnaires were used. The statistical population of this research included 17 petrochemical managers and university professors who were selected using non-probability and purposeful sampling. The first step of the current study was using the meta-composite qualitative analysis method to identify the main and sub-categories of the research. MAXQDA software was used for qualitative analysis. By extracting the main and sub-categories of the research using the results of meta-composite qualitative analysis and the Dimtel method - structural-interpretive modeling, the final model was presented. In total, the obtained pattern consists of 5 main categories. The results showed that the liquidity ratio is at the first level, the growth ratio is at the second level, the profitability ratio and the leverage ratio are at the third level, and the activity ratio is at the fourth level of the model.
