Overview of the Modular Effectiveness/Vulnerability Assessment (MEVA) Architecture

摘要

The Modular Effectiveness Vulnerability Assessment - Ground Fixed (MEVA-GF) is an engineering tool for assessing the vulnerability of fixed ground targets to conventional weapon attack. MEVA-GF is a graphical user interface (GUI) based program that provides an architecture for assembling an assessment model or simulation in modular fashion. Individual modules representing the weapon, target, weapon delivery, penetration, blast, fragmentation, etc. are linked together using a data flow paradigm that creates the assessment network. The modularity inherent in the architecture provides the user flexibility in the design of networks by offering modules with varying levels of fidelity. MEVA-GF may be used to configure a fast running stochastic model for Monte-Carlo type calculations that require hundreds of runs for statistical accuracy. Higher fidelity models may be constructed for more deterministic type studies where longer run times are not a consideration and more precision is desired. Critical components within targets may be modeled and assigned to fault trees providing a means for assessing functional damage to a target. The targets response (i.e., damage) to the weapon effects (i.e., penetration, blast, fragmentation) is output into data files and can be visualized using a three dimensional graphical representation.
