This study presents a novel decision‐making framework for the simultaneous selection and transfer of technology and equipment under uncertainty, applied to the gas industry. Using the grey DEMATEL method, the most influential and dependent criteria were identified, distinguishing between cause and effect factors. The analysis revealed that country constraints , laws of the country , and technical characteristics of the technology exert the greatest influence on other parameters. Conversely, high investment costs and after-sales service were found to be highly affected by other factors. The OPA‐G method was employed to rank alternatives, and the results showed that Alternative 3 was consistently the most appropriate option across all expert evaluations. Sensitivity analysis confirmed the robustness of the OPA‐G model, as alternative rankings remained unchanged under parameter variations. These findings provide a practical and reliable tool for technology decision‐making in complex industrial environments.
