Two bar graphs depict epistemic uncertainties in reverse logistics supply chain of demolition waste for two cases. Panel A shows the epistemic uncertainties for Case I, where quality assurance is present. The horizontal axis ranges from 0.0000 to 1.0000, and the vertical axis represents different variables labeled as X1 to X16. The bars are color-coded: orange for Status = No and blue for Status = Yes. Notable variables with higher uncertainties include X8, X16, and X7. Panel B shows the epistemic uncertainties for Case II, also with quality assurance. The horizontal axis ranges from 0.0000 to 0.6000, and the vertical axis represents different variables labeled as X1 to X16. The bars are similarly color-coded: orange for Status = No and blue for Status = Yes. Notable variables with higher uncertainties include X16, X8, and X9.Sensitivity analysis of epistemic uncertainties in Case I (a) and Case II (b). Source: Authors’ own work
