우리나라는 수출입화물의 99% 이상이 항만을 통해 해외로 운송되고 있는 관계로 해상화물 운송이 국가적으로 매우 중요한 역할을 수행하고 있다. 해상화물은 크게 일반화물(벌크화물)과 컨테이너화물로 구분되는데 컨테이너화물은 갈수록 그 비중이 증가하고 있어 국내 물류망 개선뿐만 아니라 물류비 인하와 관련해 매우 중요한 부분을 차지하고 있다. 따라서 컨테이너화물의 운송에 대한 기초 연구들은 사회경제적으로 매우 중요한 역할을 담당하고 있다. 본 연구에서는 2011년 기준 우리나라 컨테이너화물의 내륙기종점(O/D)에 관한 연구 분석결과를 중심으로 국내 수출입컨테이너의 주요 항만별, 수입 수출별, 내륙시도별 분포 현황을 살펴 본 후 그 시사점을 도출하고자 한다.

Over 80% of Korea's cargo transport relies on public roads. Such over-reliance has created a range of social problems including environmental damage. Korea thus faces an urgent need to establish an alternative mode of cargo transportation. In view of the changing international logistics environment, railway is clearly a superior mode of transport. The prerequisite task today for Korea is to enhance the competitiveness of inland railway by switching to railway and spurring new demand for cargo. This study examines inland railway cargo transport from the demand perspective. Specifically, through the use of a survey, the study identifies key factors influencing the decisions of container shippers regarding the use of railway for cargo transport. The survey responses were statistically tested using Smart PLS structural equation modeling. The results indicate that attitude toward railway use had the strongest influence on choice, while the key variable affecting attitude formation was cost.

본 논문은 내륙 운송 체계 하에서 공 컨테이너의 효율적인 운송관리 문제에 대하여 다루었다. 내부적으론 pickup and delivery 제약조건을 적용하여 특정 pick up 시간을 가지는 화물과 터미널에서의 적 컨테이너을 만족하는 차량의 스케줄링 문제이다. 차량의 내부 운송에서 공 컨테이너의 이동이나 공차의 이동 같은 불필요한 이동을 최소화함으로 효율적 운송을 할 수 있다. 또 한 모든 화물과 수입된 적 컨테이너의 pick up time 의 시간 제약으로 인한 차량의 이동 제약를 만족해야 한다. 이 문제를 해결하기 위해서 휴리스틱과 메타 휴리스틱 방법을 이용하여 근사해를 도출한다.

Inland transport becomes more and more important in connecting ports with inland. Therefore, studying on cargo flow from ports to regions has been active in progress by many researchers. However current statistical data of freight flow from origin locations to destination locations does not reflect the exact characteristics of freight flow. Also, they also do not reflect the characteristics of multimodal transport system in which cargos go through intermediate locations such as logistics center or inland container depot. In growing up the emergent need of rebuilding statistical data for freight flow from origin locations to destination locations, this paper will propose a freight flow model with logistics center and it will be verified by genetic algorithm through the simulation scenarios.

우리나라 인천항의 적체현상은 그 한계를 초과한 상태여서 체선율이 약 40%에 이르고 있다. 아울러, 수도권 대량화물의 대부분이 인천항을 경유하여 내륙수송방법을 통해 운송되므로 수도권의 심각한 교통체증을 가중시키며, 물류가격경쟁력의 저하현상을 초래하고 있다. 따라서, 운하를 건설하여 연안해송, 내륙수운 등의 수송수단을 통해 대량화물 운송을 원활히 하여 내륙교통량을 완화시키고 수송비를 절감시킬 필요성이 있다. (중략)

With development of port industry, inland transportation was also the developed. Connecting port with inland becomes more and more important. So studies about cargo flow from ports to regions are actively in progress. But freight statistics from regional to national has a problem that do not comprehend exactly with freight flow. Also these statistics don't reflect characteristics of multimodal transportation system. The objective of this paper is to analyze freight flow of container with the introduction of P/C and rebuilding freight statistics from regional to national scale.

This study assesses the appropriate amounts and applicable ranges of travel time values for freight transport modes in Korea. The findings suggest that it is possible to determine appropriate sizes and applicable ranges of travel time values of goods set for road transport mode (i.e. truck), whereas those for railway, inland waterway, marine, and air transport modes are not as easily estimated. The adequate travel time value for trucks is 20,000won/vehicle hour, and the application range of travel time value of trucks is 17,000~23,000won/vehicle hour considering other variables. The most adequate estimation method of determining the travel time value for road transport is the wage rate method, whereas the marginal rate of substitution method is more rational for railway, inland waterway, marine, and air transport modes considering the application purpose and characteristics of the goods transported.

Road transportation accounts for the largest share of cargo transport in Korea. Inland transportation is not only the beginning and completion point of container transportation, but it is also very complex and has many workers. The main job of container drivers, who play a key role in inland logistics, is to transport containers from ports and terminals to destinations. However, in addition to the main role, various container management obligations, such as cleaning containers and managing damaged containers during the transportation process, are implicitly transferred to container drivers. However, little research has been conducted on this issue. This study identified the working environment of container drivers and empirically analyzed the current status of container management responsibilities by drivers. Furthermore, it analyzed whether there was a difference in the degree of container management requirements by shipping company, terminal, and shipper. Differences in requirements for region(Busan, Kwangyang, Pohang) were analyzed, and improvement measures for the problem of transferring container management were also presented.
