Abstract

In Korea, the types and sizes of important national facilities have steadily increased as the economy has grown and industry has advanced. Not only government facilities, but also private industrial facilities, there are a number of facilities that can affect the entire country when the facility's function is lost due to terrorism. However, many important national facilities are vulnerable to external attacks due to insufficient design considerations for external intrusion and terrorism. Therefore, this study aims to develop a system that quantitatively evaluates and analyzes the physical protection system of a facility that must be designed safely from external intrusion. In addition, this system makes it possible to accurately and quickly analyze the physical protection system information for the facility at the initial stage of design by using BIM. Through this, the designer can design a facility that can satisfy the required performance of the facility's physical protection system, and it can be used to reach the standard of an increasingly strengthened trend. The BIM-based physical protection system quantitative evaluation system analyzed detection and delay factors and their attributes based on the EASI model of Sandia Nation Lab. To this end, the sequence diagram of the external intruder of the EASI model was reproduced with the space and components of BIM as edges and nodes. The reproduced Edge and Node can find the physical protection system's effectiveness and weak paths of all paths through Python-based programming. Finally, the vulnerability analysis of the physical protection system for the sample facility was performed through simulation, and an improvement plan was proposed to reach the target value through three upgrade processes.
