지하상가는 특성상 출입구에 문을 설치할 경우 피난안전에 미치는 영향을 더 면밀하게 분석할 필요가 있다. 본 연구에서는 이미 사용 중에 있는 지하상가의 출입구 중 일부 출입구에 문을 설치하는 경우에 대해 CFAST로 화재시뮬레이션을 수행하고 그 결과를 building EXODUS 피난시뮬레이션의 위험인자로 활용하여 화재위험을 고려한 피난해석을 하였다. 지하상가의 6개 출입구 중에 2곳에 문을 설치할 경우에 대해 화재피난과 일반피난으로 나누어 1,088명에 대해 피난해석을 하였다. 일반피난의 경우는 문 설치에 따른 영향이 거의 없었으나 화재피난의 경우는 문 설치로 인해 약 110초의 피난지연이 발생하였다. 또 자동문이 설치된 경우는 자동문이 열리지 않을 때가 문 설치 전보다 670초 피난지연이 발생하였다. 따라서 자동문은 화재감지기와 연동하여 개방된 상태로 정지하도록 설치되어야 하고, 문을 설치할 경우 피난안전을 위해 피난유도표시를 보강하는 것도 필요하다.

최근 건물의 대형화, 고층화, 복잡화가 이루어지고 있으며, 건축물 화재 발생건수와 이로 인한 인명 및 재산 피해의 증가함에 따라 화재피난 시뮬레이션을 통한 건축물의 안전성 점검의 필요성이 대두되고 있다. 따라서 본 연구에서는 외산 프로그램에 의존하고 있는 화재피난 시뮬레이션 분야에 한국인의 특성을 고려한 시뮬레이션 시스템을 구현하고자 하였다. 그 결과 3차원 공간 정보 기반으로 공간의 토폴로지를 생성하고, 피난 경로를 탐색하는 화재피난 시뮬레이션을 구축하였다.

Recently, the terror frequently has taken place for unspecified individuals as modern society is complicated. Especially, in case of a subway carriage fire as Daegu subway fire, because smoke spread path usually coincide with passenger's evacuation path, it will reduce visibility and can cause fatalities by asphyxiation. This study performs not only fire simulation with CFAST V6 but also evacuation simulation with EXODUS V4 for the purpose of taking measures for passengers's life safety in subway fire. As a result of evacuation simulation without fire, evacuation times are 36 s for EXODUS V4 and simple hand calculation, and when fire is occurred fire, 101 persons evacuated in 32 s. Therefore, a countermeasure of evacuation in subway carriage fire is required to repression of fire and emergency exit.

The human behavior is very important in development of simulation system for evacuation analysis. The walking speed of passenger is especially affected by dynamic effect and list due to damage and ship motion in wave. There are various methods to get an useful data for evacuation simulation. The onboard experimental approach is one of the most strong method. In this paper, the onboard experiment is performed to obtain human behavioral data. To realize ship trim and heel due to maritime casuality, the passage model for experiment is made. The experiment is carried out at dynamic and static condition respectively using the ship with passage model. The result is evaluated and it will be reflected in evacuation simulation tool.

본 논문은 규칙기반 에이전트를 이용하여 여객선 화재시 피난행동특성을 고려한 승객행동모델을 제안한다. 기존 시스템들은 승객의 속도만을 반영한 속도기반모델을 사용하였다. 속도기반모델은 승객의 신체적 특징만 고려한 모델로 피난행동특성을 반영하기 어렵다. 이 문제점을 해결하기 위해 규칙기반 에이전트로 피난행동특성을 반영한 승객모델을 모델링하였다. 규칙기반 에이전트는 지식베이스와 추론엔진으로 구성된다. 지식베이스에는 피난행동특성들 중에서 다양한 행동 패턴을 보여줄 수 있는 예제를 선택하여 규칙형태의 지식으로 표현하고, 추론엔진은 지식을 전방추론하여 승객의 행위를 결정하도록 구현하였다. 이승객모델을 IMO MSC/Circ.1238의 문제 8에 적용하여 시뮬레이션을 진행한 결과 규칙기반 에이전트로 모델링한 승객이 다양한 인간의 행동 패턴을 표현할 수 있음을 검증하였다.

In this research, we determine the proper number of entrances in the evacuation facilities for civil and military personnel. The current standards on the emergency evacuation facility only sets the number of possible evacuees and the according architectural floor area since the evacuation have been completed. However, other than static standards such as the floor area, there is needs to consider the dynamic standards along with allowable evacuation time such as the number of entrance, staircases and so on. Therefore, we need to consider the number of entrances and their location in order to account for the allowed evacuation time of particular number of people in a set area. The outcome could be contributed to the standards which should contain the dynamic conditions associated with evacuation.

In recent years, building architecture has become increasingly complex and larger in scale to accommodate many people. In densely populated facilities, the interiors are becoming more intricate and high-rise, with narrow corridors, hallways, and stairs. This poses challenges for evacuating occupants in case of emergencies such as fires, making it crucial to assess the evacuation safety in advance. In evacuation safety research, there are significant limitations to theoretical studies owing to their association with crowd behavior and human evacuation characteristics, as well as the risks associated with experiments involving human participants. Consequently, evacuation experiments conducted using simulation-based methodologies are gaining recognition worldwide. However, crowd simulations face validation difficulties because of variations in crowd movement and evacuation characteristics across different cases and scenarios, as well as the challenge of accurately reflecting human characteristics during evacuations. In this study, we investigated validation methods for evacuation simulations using the SAFEGUARD validation data set (SGVDS) provided by the University of Greenwich, UK. The SGVDS collects data on crowd evacuations through actual evacuation tests conducted on ColorLine's large RO-PAX ferry and Royal Caribbean International's cruise ships. The accuracy of the crowd simulations can be validated by comparing SGVDS and crowd simulation results. This study will contribute to the development of highly accurate crowd simulations by verifying various crowd simulations.

Recently as the rapid increasing of the elderly, silver housing has grown up. Though much fire evacuation and safety law, fire accident is most dangerous problem in our society. So this study is the purpose to analyze evacuation safety in urban silver housing of floor planning by corridor types using human behavior simulation. The methodology of this study is 'Literature Review' and 'Simulation'. This study has been carried out on silver housing's definition, types, fire safety theory and relation law. To proof evacuation safety, this study measured escaping time, longest distance, and bottleneck counting using human behavior simulation. This study use game engine simulation program to analyze 6 corridor types experimental model. As the result of simulation, this study compare between ASET and simulation result. The result come down to 3 part. First, double loaded corridor type is the most dangerous on urban silver housing. Second, Safe shelter's location and number cause increasing of escaping time. Lastly escaping time is influenced by behavior of agent, bottle neck strike frequency.

In the last years there have been some severe accidents with passenger vessels. So, International Maritime Organization(IMO) has recognized that computer stimulation of the evacuation may be required for passenger vessels. Human elements is a key issues of escape analysis on shipboard. There are technical requirements to simulate of escape analysis for human elements. Technical requirements include model of ship structure, evacuation algorithm, human behaviour analysis and influence of ship listing/motion. This paper provides the key issues and technologies of simulation for human escape on shipboard.

There have been many accidents of passenger ships on the sea and they have caused a big loss of human lives. Maritime Safety Committee(MSC) of International Maritime Organization(IMO) made evacuation analysis of Ro-Ro passenger ships mandatory in order to save as many lives as possible at the time of accident. But this is a temporary regulation and HSC/IMO ties to introduce a performance-based regulation to improve the effect of regulation. Simulation-based evacuation analysis is the basis of performance-based regulation. In this paper, we performed a simulation-based evacuation analysis on a passenger ship, which is usually used in the plying between land and islands in Korea, with EXODUS system. Through inspecting the results from this analysis in more detail, we can make a proposal to improve the safety of passenger ship. Finally we describe the features of IMEX(Intelligent Model for Extrication Simulation), a new evacuation model being developed in KRISO.
