The greater the integration of a company’s competitive values against other competitors, the more influential the supply chain flexibility is due to a better understanding of market drivers. The purpose of this study is to evaluate the rough analysis process to select the most effective functions of supply chain flexibility based on the propositions of the integration of competitive values in the petrochemical industry. The methodology of this research is hybrid, and the Delphi and Rough collection were used to perform meta-synthesis analysis. The target population in the qualitative sector was similar research and academic experts in industrial management. However, the target population was a small number of 23 managers with experience in petrochemical companies, which is acceptable from the statistical population due to the need to analyze the Rough process. In this study, based on the combined analysis of selected researches, five propositions of competitive value integration and five components of supply chain flexibility were determined, which entered the Rough collection analysis phase according to the confirmation of theoretical adequacy based on the Delphi analysis. The results in this section identify the most compelling propositions for integrating the competitive values of companies operating in the petrochemical industry: demand-based management propositions (P2), creating innovative values (P3), and reducing operating time (P5), which affects the flexibility of the supply chain and causes the flexibility of financing as the most effective component of the flexibility functions in the supply chain in the petrochemical industry. https://pbr.put.ac.ir/article_137542_80fb85c52e205761b434da7ea243e373.pdf
