|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.
