해상운송에 있어서 컨테이너 운송수요의 증가와 변화에 효율적으로 대응하기 위해서는 공 컨테이너(Empty Container)의 효율적인 관리 및 최적화 할 수 있는 기술이 요구되고 있다. 본 연구에서는 다품목을 고려한 다수의 포트간의 공 컨테이너 재배치문제를 다루고자 한다. 공 컨테이너의 효율적인 관리 및 운영을 위한 수리 모형을 통해 지역간의 공 컨테이너 재배치량과 지역내 데포간의 공 컨테이너 재배치량을 결정하고자 한다. 간단한 수치실험을 통해 해상 지역내와 해상 지역간을 통합한 다 지역간의 재배치 방안의 효율성올 보이고자 한다.

At the adjacent sea area of Busan Central Wharf, a variety of vessels, such as middle-large passenger ships, small hugh speed crafts, container ships, cargo ships and working boats as well as small miscellaneous vessels are freely sailing comparatively without special rules and marine traffic control. In this research, we analyzed traffic stream and navigational characteristics cf main traffic route based on statistics and distribution of tracks by ship's type and tonnage cf the passing vessels after conducting marine traffic survey twice using exclusive software. We examined the traffic safety of the passing vessels by classifying the sea area by each function based on the analysis about this traffic situation, and analyzing the effect by designating 'Inner passage'. We also studied the plan for the effective rearrangement cf Central Wharf considering basically the traffic safety of arrival and departure in a point of view of navigators.

At the adjacent sea area of Busan Central Wharf, a variety of vessels, such as middle-large passenger ships, small fast sailing ships, container ships, cargo ships and working ships as well as small miscellaneous vessels are freely sailing comparatively without special steering and sailing Rules and marine traffic control because exclusive wharfs in accord with their purpose and use have been arranged in each wharf. In this research, we analyzed traffic stream and navigational characteristics of main traffic route based on statistics and distribution of tracks by ship's type and tonnage of the passing vessels after conducting marine traffic survey twice using exclusive software by targeting the sea area during the period of time. We examined the traffic safety of the passing vessels by classifying the sea area by each function based on the analysis about this traffic situation, and analyzing the effect by designating 'Buknea passage'. We also studied the plan for the effective rearrangement of Central Wharf considering basically the traffic safety oif arrival and departure in a point if view of navigators.

통신기술이 1 세에서 5 세대로 발전하는 동안 해상물류의 핵심인 컨테이너는 기능상의 큰 발전없이 과거에 머물러 있다. 이에 본 논문에서는 컨테이너의 위치 및 상태 정보를 수기로 관리하던 기존의 방식에서 벗어나 IoT 장비를 활용해 실시간 위치 파악, 상태 모니터링 및 자동화 등을 통해 물류의 가시성을 확보하고 컨테이너를 효율적으로 재배치함으로써 비용 절감 및 새로운 서비스 창출하기 위한 스마트 컨테이너를 제안한다. 부가적으로, 태양열판을 이용한 전원공급, 펠티어 소자를 이용한 냉방기능을 제공함으로써 신선 식품 배송의 핵심인 풀 코드 체인(Full Cold Chain) 플랫폼으로 활용범위를 넓히고자 한다.

In the present maritime traffic conditions of Mokpo harbor, there exist many hazardous factors which may lead to huge accidents including marine oil pollution We analyze marine traffic environments including traffic congestion, natural conditions, maritime traffic accidents in the last 10 years, the fishery status, operation of traffic routes and management of navigational aids and regulations relating ships' routeing both in and out of the country. Consequently, this work is to propose improved marine traffic system in future.

Due to the construction of Incheon Grand Bridge, there is driven a necessity for rearranging the function of Inner Port with the development of Outer South Port. In this paper, I'd like to simulate the port operation levels of Lock Gate in Inner Port with estimating the traffic volumes of 2011 and 2015, which will reveal the Demurrage Cost and the Accumulation Cost of Freight in Inner Port. Finally I will evaluate the economic movement effects of the container ship's calling from Inner port to South Port/Outer South Port from 2011 to 2015. The results are as followings ; (1) The average utilization of Lock Gates are reduced by $7\sim8$ percentage point. (2) The mean queueing value are saved by 25 percentage point. (3) The Demurrage Cost and the Accumulation Cost of Freight except Lock Gate charges and the Benefit of Routeing Reduction are saved about 800 million Won annually.

The purpose of this study: firstly, investigate cognition of affiliated members about manpower distribution of the South Regional Headquarters Korea Coast Guard(SRH-KCG) and danweis. Secondly, seek ways to reasonable manpower distribution of SRH-KCG and danweis. And this study's research subjects are five coast guards(Busan coast guard, Tongyeong coast guard, Yeosu coast guard, Jeju coast guard, Seogwipo coast guard) belonged to SRH-KCG. The results of this study: firstly, 56.7% of affiliated members approved the need to organizational diagnosis. Secondly, must manpower loading in order of Busan coast guard Tongyeong coast guard Jeju coast guard. Thirdly, must manpower loading in order of maritime safety division the security division criminal investigation divition.

광양항은 4개의 항로가 설정되어 있다. 광양항 제1항로는 광양항 항계에서 "해사안전법" 제10조에 따른 교통안전특정해역(여수구역)과 연결되어 있고, 낙포각 사포부두(원유부두 북측) 전면 해상에서 광양항 제2항로와 광양항 제3항로 및 제4항로가 분기 합류된다. 이 글은 광양항 제1항로에서 제2항로로 진입하고 있던 선박과 광양항 제3항로에서 제1항로로 진입하고 있던 선박 사이에 발생한 충돌사건의 개요와 원인을 살펴보고, 개항내 항로가 분기 합류되는 수역에서 합의항법이 적용될 수 있는 점과 현행 광양항 항로의 재배치 필요성, 여수지방해양항만청 고시로 규정하고 있는 광양항내 안전한 속력을 광양항에 입출항하는 모든 선장 및 항해사가 알 수 있도록 해도 및 "Guide to Port Entry"에 반영할 것, 그리고 VTS관제사가 광양항에 입출항하는 선박이 안전한 속력을 준수하도록 권고 또는 지시 필요성 등의 교훈 및 개선사항을 제시하고 있다.

Containerization of cargo transportation has been norm in the word wide maritime services, but containerized trades are typically unbalanced in terms of the number of inbound and outbound containers. Therefore it is critical for shipping companies to find operating policy such as the repositioning of empty containers or replenishing of short-term leasing containers from leasing companies to satisfy the freighter's demands of containers. This paper develops a simulation model using ARENA to establish shipping company's operational policy to relocate and replenish empty containers. Furthermore, this study proposes simple and heuristic empty container repositioning rules to minimize the relevant cost in terms of leasing, repositioning, and inventory holding costs.
