The primary objective of this study was to analyze the causal relationships between sustainable performance management dimensions and the implementation of innovative and economic production methods in Iran’s petrochemical industry under sanctions conditions. In terms of purpose, this research is applied, and in terms of nature, it is a descriptive–analytical study based on a quantitative approach. The statistical population consisted of senior managers, production experts, and specialists in the fields of sustainability and innovation within the country’s petrochemical companies. Using Cochran’s formula, a sample size of 384 participants was determined. Data were collected through a researcher-developed questionnaire and analyzed using Pearson correlation analysis, multiple regression analysis, and Structural Equation Modeling (SEM). Furthermore, to enhance prediction accuracy and prioritize indicators, the metaheuristic algorithms Adaptive Neuro-Fuzzy Inference System (ANFIS), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO) were employed. The findings revealed that the environmental dimension, sustainable innovation, economic dimension, and sustainable supply chain management exerted the strongest effects on the implementation of innovative production methods, whereas the human rights and diversity and inclusion dimensions did not demonstrate statistically significant effects. The results further indicate that emphasizing resource management, green technologies, and supply chain resilience can facilitate the advancement of resilience and sustainability in Iran’s petrochemical industry under sanctions conditions.</p> https://www.journalmbs.com/index.php/jmbs/article/download/350/272
