Abstract

Lately, losses and damage from natural disasters have been increasing. Researchers across various fields in Korea are trying to come up with a response plan, but research for evacuation plans is still far from satisfactory. Hence this paper proposes a model that could find an optimized evacuation route for when disasters occur over wide areas. Development of the model used methods including the Dijkstra shortest path algorithm, feasible path method, genetic algorithm, and pareto efficiency. Computations used parallel computing (SPMD) for high performance. In addition, the developed model is applied to a virtual network to check the validity. Finally the adaptability of the model is verified on a real network by computating for Gumi 1stNational Industrial Complex. Computation results proved that this model is valid and applicable by comparison of the fitness values for before optimization and after optimization. This research can contribute to routing for responder vehicles as well as planning for evacuation by objective when disasters occur.

최근 들어 재난 발생으로 인한 재산 및 인명피해가 속출하고 있다. 이에 따라 국내 여러 분야에서 분야별 대응방안 모색을 위해 노력하고 있지만 대피매뉴얼 작성을 위한 연구는 미비한 실정이다. 본 연구에서는 공단과 같은 산업지역에서 대규모 대피가 필요한 사고가 발생하였을 때, 대응방안에 따른 최적의 대피경로를 산정하는 모형을 개발하였다. 모형개발에는 Dijkstra 최단경로 알고리즘, 가능경로법, 유전자 알고리즘 및 파레토 최적해 산정 등을 통하여 모형을 개발하였고, 병렬처리를 통하여 연산시간을 단축시킬 수 있도록 하였다. 뿐만 아니라 개발된 모형을 가상네트워크에 대한 적용을 통해 타당성을 검증하였고, 구미 국가산업 1단지를 대상으로 적용하여 실제 지역을 대상으로 한 모형의 적용성을 검증하였다. 모형을 이용하여 목적함수별 최적경로를 산출한 결과, 최적경로 산출 이전보다 좋은 결과를 얻을 수 있어 타당성이 검증되었고, 실제 지역을 대상으로 연산한 결과를 통해 모형의 적용성도 검증되었다. 본 연구 결과는 재난을 대비한 대응목적별 대피매뉴얼의 작성뿐만 아니라, 재난 발생 시 대응차량의 진입경로 산정에도 도움이 될 것으로 판단된다.
