Abstract This study proposes a method to derive an optimal alternative to the reinforcement point factoring indoor accessibility by evaluating the physical protection system for architectural facilities with many internal users among nationally significant facilities. The point of high accessibility is when an area is frequently used by insiders; consequently, when security is strengthened, indoor accessibility is lowered. Therefore, a point with a high effect of reinforcement physical protection system was derived while minimizing the deterioration of the indoor accessibility of internal users. To verify, a BIM model based pilot facility was selected, and vulnerability analysis was performed factoring all access routes using a spatial network. For the reinforcement method, improving the performance of the protection point and adding a protection point was considered. As a result of this simulation, 45 intrusion routes, 45 routes of physical protection effectiveness values, and 33 reinforcement alternative points were derived. A total of 72,428 reinforcement cases were analyzed, and 11 optimal alternatives were gleaned. In conclusion, this study was conducted to find alternatives for places that should be strengthened at low cost for facilities needing a physical protection system. The effectiveness of this proposed method was confirmed through a simulation and is possible to potentially use as a quantitative design criteria, evaluation, or reinforcement of a physical protection system for nationally significant facilities.
