Accuracy of Vulnerability Integrals

Abstract

This report investigates the accuracy of vulnerability indicators that represent average vulnerability either over a threat dispersion area or over the silhouette of a target. Mathematically, these indicators are surface integrals of local vulnerability over a reference plane normal to the direction of the threat. In applications, the integrals are computed by discrete numerical integration. The accuracy of the resulting indicators depends on the accuracy of the local vulnerability, the detail of the target description and on the properties of the numerical integration method. This report provides error estimates for the latter two error sources. The estimates help one to determine the appropriate target detail and integration procedure so that the overall accuracy of the vulnerability indicator is at the achievable level. Keywords: Monte carlo computation, Detail of target description.
