Summary of the case-study

This case-study addresses the problem of defining, characterizing and propagating uncertainty in an exposure model. Uncertainty analysis is used to assess the impact of data precision on model predictions. A common complaint associated with worst-case approaches to risk assessment is that the use of highly conservative values for each input variable results in significant overestimation of actual risk and/or exposure factors.
