Uncertainty Quantification and Sensitivity Analysis Methodology for the Advanced Joint Effectiveness Model (AJEM)

Abstract

The Advanced Joint Effectiveness Model (AJEM) is a joint forces model developed by the U.S. Army that is used in vulnerability and lethality (V/L) predictions for threat/target interactions. This complex model primarily generates a probability response for various components, scenarios, loss of capabilities, or summary conditions. Sensitivity analysis (SA) and uncertainty quantification (UQ), referred to jointly as SA/UQ, are disciplines that provide the working space for how model estimates changes with respect to changes in input variables. A comparative measure that will be used to characterize the effect of an input change on the predicted outcome is developed in this report. This measure will provide a practical context that stakeholders can better understand and utilize. We show graphical and tabular results using this measure.
