부산항 신항은 2018년도 기준으로 컨테이너 14,559천TEU를 처리하였으며, 환적은 58.89%을 점유하고 연평균 6.41% 증가되고 있다. KMI 2017년도 물동량예측량의 연평균 증가율을 적용하면 부산항 신항의 환적화물량은 2030년에는 12,326천TEU에 이를 것으로 전망된다. 아울러, 환적화물 중에서 타부두 환적물량은 2018년도 기준 26.3%이며 총 신항 물동량대비 15.51%에 이르고 있다. 이러한 증가추세를 고려하면 2030년 타부두 환적물량은 3,080천만 TEU에서 3,600천TEU에 이를 것으로 전망된다. 한편, 타부두 환적물량 증가에 따른 부두간 컨테이너 이송량이 증가되고 있으며, 이러한 화물 증가량은 배후 임항도로의 정체를 초래를 야기시키어 항만 경쟁력을 약화시키는 원인으로 작용된다. 본 연구에서는 부산항 신항에서 타부두 환적을 위한 전용시스템의 도입 평가요소 우선순위에 대하여 터미널 운영사, 선사, 항만공사 및 관련 전문가에 대하여 설문을 실시하여 도출하였다. ITT 도입 평가요소 항목으로서 생산성, 안정성, 투자효율성, 운영효율성, 정책부합성에 대하여 검토하였으며, 각 하위 평가요소로서는 각각 3개씩에 대하여 총 15개의 하위요소에 대하여 평가를 실시하였으며, 이를 통하여 항후 부산 신항의 ITT 도입시 평가 요소로 활용될 수 있을 것으로 기대한다.

The Korean government establishes a strategy to develop the Busan New Port as a world ranking two transit-oriented port. This paper aims at presenting an efficient inter-terminal transport (ITT) system in the Busan New Port as a method of achieving the government strategy. First, it presents results of long term forecast for the inter-terminal transportation volume in the port. Second, it proposes two systems to treat ITT in the port; Double stack Multiple Trailer System (DMTS) and Rail-based transportation system. The implementation methods in the port are introduced in detail for the both systems, and the required number of the systems and costs are calculated for implementation of both the systems. B/C for DMTS is analyzed to 3.7, moreover unit-fare per [$ton{\cdot}km$] can is lowered to 67% against current fare. DMTS is shown to highly potential for efficient ITT in the port.

The Korean government establishes a strategy to develop the Busan New Port as a world ranking two transit-oriented port. This paper aims at presenting an efficient Inter-Terminal Transportation system in the Busan New Port as a method of achieving the government strategy. It proposes four systems to treat Inter-Terminal Transportation in the port; Double stack Multiple Trailer System (DMTS) Rail-based transportation system, Private road for Inter-Terminal Transportation, and platform for Inter-Terminal Transportation. This is shown to highly potential for efficient Inter-Terminal Transportation in the port.

Competition between ports around the world is intensifying to attract transshipment cargo. However, recently, there have been concerns about the departure of transshipment cargo volume at Busan Port, such as the lifting of the cabotage policy in China's shipping sector and the implementation of a safe fare system. In terms of operation, terminal congestion and vehicle waiting time are seriously occurring due to imbalance in the transshipment volume of each terminal and vehicles concentrated in a specific time period. In this paper, we propose a method of inter-terminal transportation (ITT) using buffer space to solve the problem caused by inefficient ITT systems and presented a mixed integer programming (MIP) for the problem. The effect of using the buffer space was analyzed for various work volumes and capacity fluctuation ranges by applying the terminal congestion pattern and ITT vehicle in/out pattern based on the Busan New Port data.

The purpose of this study was to identify evaluation factors and analyze the relative importance among factors to select a suitable transportation method for transferring the increasing amount of transshipment at multiple terminals at the Busan new port. To accomplish this, the evaluation factors were selected through a literature survey and brainstorming of a group of experts associated with the port operation, and were classified into five major factors and 15 middle factors. The evaluation factors classified hierarchically were surveyed relative to workers in organizations such as shipping companies, port corporations, container terminals, and related ministries. The importance of each factor was calculated using the hierarchical analysis process (AHP). As a result of the importance analysis, priority was assigned in order of safety, productivity, investment efficiency, operational efficiency, and policy conformity. Through this, it was necessary to select a suitable transportation method for the transshipment cargo in terminals while focusing on the cargo and terminal security and preventing accidents. As a result of calculating from six ITT transportation candidates, the priority was determined in order of monorail, Autocon, and so on as ITT transportation suitable for the Busan new port..

This paper presents results of a study for development and application of container massive transportation system. The system is aimed to improve competing power of Korean container ports. This paper selects Double stack Multi-Trailer System (DMTS) under consideration of pros-con analysis between three systems alternatives as well as operation process of existing Korean container terminal companies. An analysis of turning radius is undertaken for applying the system. Key elementary technologies was derived by patent analysis. DMTS has no problems in utilization to existing Korean container ports. Further, the system is expected to highly potential to improve operational efficiency in the container ports thanks to its high unit transportation capacity.

Busan New Port has continued to expand its capacity to handle transshipment cargos exceeding 50 percent of its total volume, but it is considered inefficient because of the work scheduling based on the worker experience. In particular, depending on the transshipment task situation, which often requires an external truck, excessive congestion caused by the vehicle's delay can lead to increased logistics costs and social costs. One way to resolve this issue is to minimize the single transport of the truck and to maximize dual-cycle transport by putting the finished truck into another task. Therefore, we would like to study how to efficiently schedule transportation transshipment cargos between terminals considering dual-cycle.

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.

Busan Port is being operated inefficiently by a number of container terminal operators, which are dispersed in small groups. In particular, the small terminal at Busan Port is causing the dispersion of quantity, the increase of ITT cargo and the occurrence of a ship waiting at sea as the ship's Alliance became larger in 2016. As a result, studies such as integrated operations for the larger container terminals are being conducted. Therefore, in this study, we intend to set up a type of integrated operation for terminals at the new port of Busan and measure the practical effects through simulation to present an ideal direction for integrated operation.

The inefficient operation of Busan New Port is due to container-terminal operators being dispersed in small groups, rather than being integrated. This dispersion increased following the reorganization of global shipping alliances in 2016 and causes unnecessary Inter-terminal Transportation(ITT) and ship delays. Studies of integrated operations for larger container terminals show that integration is not going well, however, due to the pre-emptive task that follows the integrated operation. Therefore, in this study, we divided the integrated operation into stages based on a simulated model of the container terminals in Busan New Port. The simulation took into account future increases in the ship's enlargement and terminal congestion, and the operational effects of each type of integrated operation were analyzed and evaluated.
