Analysis of uncertainty in material flow analysis

The uncertainty range and likely values of flow data can vary considerably based on the HS method or MC simulation. After analyzing the relationship between the uncertainty range and flow data, likely values can be derived via comparisons of uncertainty method processes, and the uncertainty analysis results of the HS may deviate greatly from those of the MC method. In this scenario, MC simulation is needed to analyze MFA uncertainty, although it requires greater efforts. The results presented here provide new insights and recommendations for further MFA research.
