The present study aimed at investigating the risks of various layers and the resilience of petrochemical industry supply chains and its function in the analytical model. This study was developmental in terms of purpose and of descriptive- mathematical models in terms of method. In order to test the model, 50 senior and middle managers from 9 Iranian petrochemical companies were examined to rank the resilience of risks in the companies they were working. In addition, the scoring of risk and resilience of upstream, organizational and downstream processes of these companies was examined. The research tool allowing the respondents to assess the level of risk in the supply chain was derived from the Wagner and Bod’s model (2008). In this study, the research tools were updated based on risk grouping. In addition, the items associated to the evaluation of supply chain resilience in this study were defined based on to the supply chain resilience criteria to the items of stability, redundancy, high-thinking, reaction, and recovery efficiency being regarded the same for all three processes. Since the variables had a various frequency distribution, in this study the threshold levels of Tabachnick and Fidell (2007) were used, such that 0.32 was equal to weak, 0.45 was appropriate, 0.55 was good, 0.63 was very good and 0.71 was excellent. The results indicated that although a supply chain system may have a higher resilience than its risks, its layers may be still at risk.
