초록

본 논문에서는 도시 내 교통 혼잡 문제를 해결하기 위한 새로운 혁신 기술 중 하나인 에어 택시 운영에 관한 연구를 다룬다. 성공적인 기술 도입과 합리적인 운영을 위해 초기에 고려해야 할 문제 중 하나인 수직이착륙장(vertiport) 위치 결정 문제를 다룬다. 교통수단 이용에 따른 비용과 이동시간을 고려하여 각 경로에서의 교통수단 예측 수요 확률을 이산 선택 모형을 활용하여 구하고, 이를 반영하여 에어 택시 이용률의 최대화를 목적으로 하는 수리적 모형을 제안한다. 본 수리적 모형은 NP-난해(NP-hard) 문제로, 위치 결정 문제를 해결하기 위한 효과적이면서 효율적인 문제 해결방법론이 필요하다. 단순히 최적화 모형을 제안한 기존 연구와 달리 본 연구에서는 교차-엔트로피 알고리즘(cross-entropy algorithm)을 활용한 문제 해결 방법론을 제안하고, 수치 실험을 통해 알고리즘의 효과성과 효율성을 확인한다. 문제 해결 방법론의 학술적 우수성 외에도, 실제 데이터 및 에어 택시 활용 계획을 고려한 의사결정의 제시는 실무적인 활용 가능성을 높일 수 있음을 시사한다.

This paper deals with the operation of air taxis, which is one of the latest innovative technologies aimed at solving the issue of traffic congestion in cities. A key challenge for the successful introduction of the technology and efficient operation is a vertiport location problem. This paper employs a discrete choice model to calculate choice probabilities of transportation modes for each route, taking into account factors such as cost and travel time associated with different modes. Based on this probability, a mathematical formulation to maximize the utilization rate for air taxi is proposed. However, the proposed model is NP-hard, effective and efficient solution methodology is required. Compared to previous studies that simply proposed the optimization models, this study presents a solution methodology using the cross-entropy algorithm and confirms the effectiveness and efficiency of the algorith through numerical experiments. In addition to the academic excellence of the algorithm, it suggests that decision-making that considers actual data and air taxi utilization plans can increase the practial usability.
