Introduction to Modeling Procedures for Physical Protection Vulnerability Assessment

There is a method for evaluation physical protection performance of facility, which is called vulnerability assessment (hereinafter refer to as "VA"). VA include expert judgment, table-top exercise, computer simulation, physical protection training, and time series analysis. In these assessment tools, the most appropriate tool to comprehensively assess the actual performance of a facility is physical protection training, but there are many constraints such as time, space, manpower, budget, and safety. For the above reason, computer simulations are being used in various fields today. Simulation is a method to solve problem by modeling the characteristics of the reality. Although it takes more time for initial modeling than actual physical protection training such as data collection and 3D CAD work. However, once a reliable model is obtained for a facility, various simulations can be carried out using it. In this paper, we will discuss general VA modeling procedure, and concrete part will be described based on AVERT, a US commercial tool that KINAC is studying. In this paper, the procedures and methods for constructing model for VA simulation are mentioned in detail. In addition, we briefly introduced results of VA simulations of virtual facilities and explained what results of vulnerability simulations are. We will introduce simulation procedures of complex facilities through future studies, and introduce simulation results and analysis methods. Finally, we will also introduce our own vulnerability assessment simulation program currently being developed by KINAC.
