Sensitivity of the Shotgen and VAREA Computer Programs as Determined from Their Application to the ZIL-157 Truck.
Abstract
This report presents the results of a parametric sensitivity analysis of the SHOTGEN and VAREA computer programs. The SHOTGEN program passes parallel rays through a geometric model of a target and prepares an output file containing detailed information about the target surfaces encountered on each ray. The VEREA program then simulates the passage of projectiles or weapon fragments along these rays and computes the probability of killing the target with each specified threat along each trajectory. The results are summarized and output in the form of vulnerable areas for use by survivability/vulnerability analysts. By independent variation of each of the important input parameters and analytical submodels, an estimate of the sensitivity of the final vulnerable areas to these factors was obtained. These sensitivity estimates are then input to a sample error analysis. The studies reported include four different kill categories from two attack aspects of a military cargo truck. Complete tabulations of vulnerable areas sensitivities, and expected errors are tabulated in the appendices. (Author)
