초록

부산항은 다수 터미널 운영사에 의해 분리 운영되고 있어 ITT(Inter-Terminal Transportation) 물량이 다수 발생한다. ITT 물량발생은 추가 운송비용, 공차운송, 차량 대기 및 터미널 혼잡 등 다양한 문제를 초래해 부산항 경쟁력을 약화시키고 있다. 그 중 공차운송 문제는 부산항 ITT 운영에 있어서 비용 문제를 악화시키는 대표적인 요인이지만 부산항의 ITT 복화율은 낮은 수준에 머물고 있다. 부산항 환적 경쟁력 강화를 위해서는 ITT 복화율을 높일 수 있는 방안이 필요하다. 따라서 본 연구는 ITT의 복화율 개선을 위해 완충지역을 활용한 복화운송 최대화 수리모형을 제시하였다. 그리고 실제 운영 데이터에 기반한 실험을 통해 완충지역 활용에 따른 복화율 개선 효과를 분석하였다.

Busan Port is operated separately by a number of terminal operators, resulting in a large number of ITT (Inter-Terminal Transportation) volumes. The occurrence of ITT volume causes various problems such as additional transportation cost, empty truck trips, truck delays and terminal congestion, weakening Busan Port's competitiveness. Among them, the empty truck trip problem is a representative factor, that exacerbates the cost problem of the ITT operation at Busan Port. But the ITT backhaul rate at Busan Port remains low. To strengthen the transhipment competitiveness of Busan Port, it is necessary to increase the ITT backhaul rate. In this paper, to improve ITT backhaul rate, we present a mathematical model for maximizing backhaul transport using buffer space. And we analyzed the improving effects of backhaul transport using buffer space through experiments based on actual operating data.
