Abstract

This paper proposes the effective method for classifying the working spates and modelling the environments, when complex working environments of AGVS(Automated Guided Vehicle System) ate changed. And, we propose the shortest path searching algorithm using the A* algorithm of graph search method. Also, we propose the methods for finding each AGV's travel time of shortest path. Finally, a simple example is included for visualizing the feasibility of the proposed methods.

본 논문에서는 AGVS(Automated Guided Vehicle System)가 여러 복잡한 작업 환경 또는 작업 환경 변경 시 좀 더 유연하게 운용될 수 있도록 작업환경 내에서 AGVS에 필요한 작업공간요소를 분류하고 이들을 모델링하는 방법을 제안한다. 또한, 그래프 탐색 방법인 A* 알고리즘을 이용하여 AGV의 최단 경로 탐색 알고리즘을 본 논문의 작업환경 요소로서 재 표현한다. 생성된 최단 경로와 본 논문에서 가정한 AGV의 속도 테이블을 이용하여 운행 중인 AGV의 경로 점유 시간 알고리즘을 제안한다. 마지막으로 간단한 시뮬레이션을 통하여 제안한 방법의 적용 가능성을 증명한다.
