여객선의 안전은 인명의 안전과 직결되므로 이에 발맞추어 국제해사기구 (International Maritime Organization, IMO)는 빈번히 발생하는 선박의 전복 사고로 인한 인명 피해를 최소화하기 위하여 승객탈출분석 (Passenger Evacuation Analysis) 적용 지침을 꾸준히 개정 및 보완하고 있다. 승객탈출분석의 목적은 설계 단계에서의 탈출 설비의 배치 적합성 판단 및 배치된 탈출 설비를 이용하여 지침 상 규정하는 최대허용탈출시간 (Maximum allowable evacuation duration) 내에 탈출이 가능한 지를 분석하는 것이다. 본 논문에서는 승객탈출분석에 관한 지침의 개정 동향 및 최근 개정된 승객탈출분석 지침 (MSC.1/Circ.1533)의 개정 방향에 대하여 소개하고자 한다. 또한 탈출 해석 관점 한국해양과학기술원에서 개발 중인 인명대피안내시스템의 유효성을 검증하기 위하여 2016년 10월 수행 된 인명대피실험과 지침 상 규정하는 고도화 알고리즘 (Advanced algorithm) 기반 승객탈출 시뮬레이션 (Maritime EXODUS)의 비교 결과를 바탕으로 해당 지침 적용 시 고려사항에 대하여 고찰하고자 한다.

This paper presents a simulation for passenger ship evacuation considering determination of evacuating direction based on walking direction potential function. In order to determine walking direction of a passenger, his/her position in two dimensional plane was adopted as a design variable, and fixed boundaries such as walls and obstacles were adopted as constraints. To solve this optimum problem, a walking direction potential function was adopted as an objective function. This potential function was configured as a kind of penalty function and it contained two components. One is a potential function concerned with the distance to the destination, and other is a potential function based on the effect of walls and obstacles. To determine evacuating direction, this problem was solved by minimizing the walking direction potential function every unit time during the simulation. The crowd behavior of the passenger consisted of the flock behavior, a form of collective behavior of a large number of interacting passengers with a common group. With the proposed algorithm, the test problems in International Maritime Organization, Maritime Safety Committee/Circulation 1238(IMO MSC/Circ.1238) were implemented and the direction of passengers and total evacuation time was analyzed.

This paper presents a simulation for passenger ship evacuation considering the inclination of a ship. In order to describe a passenger's behavior in an evacuation situation, a passenger is modeled as a rigid body which translates in the horizontal plane and rotates along the vertical axis. The position and rotation angle of a passenger are calculated by solving the dynamic equations of motions at each time step. To calculate inclined angle of damaged ship, static equilibrium equations of damaged ship are derived using "added weight method". Using these equations, physical external forces due to the inclination of a ship act on the body of each passenger. The crowd behavior of the passenger is considered as the flock behavior, a form of collective behavior of a large number of interacting passengers with a common group objective. Passengers can also avoid an obstacle due to penalty forces acting on their body. With the passenger model and forces acting on its body, the test problems in International Maritime Organization, Maritime Safety Committee/Circulation 1238(IMO MSC/Circ.1238) are implemented and the effects of ship's inclination on the evacuation time are confirmed.
