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.

The value of time in freight transportation describes the importance of goods during transport and shows the direction of efficient logistic management having inventory cost in transporting The value of time differs from class to class in freight transportation. It is due to the differences of shipper's willingness to Pay for time saving. In this research the value of time in intercity freight transportation of manufacturers in Korea was estimated as follows: first, the Perception factors which were the important criteria of shippers for choosing truck were sampled. second, the shippers were classified into three homogeneous classes. third, the value of time of each class was estimated by using multinominal logit model. The results of this research showed that the value of time in freight transportation was different from every class, that the shipper had to Pay 1,680 won for saving one hour Per each shipment, and that the inventory cost in transporting occupied 9.54% in the mean freight Price.

본 연구는 중국의 WTO 가입 이후 시장규모 확대에 따라 동북아지역 국가들이 자국의 역할 선점과 경쟁력 확보를 위해 취하고 있는 항공화물운송부문의 시설운영과 전략추진 방향을 살펴봄으로써 우리나라의 항공 화물 운송 산업이 보다 경쟁력 있는 산업으로 역할과 제 기능을 다 할 수 있도록 하는데 목적이 있다. 장래 동북아지역 한 · 중 · 일 3국간 항공화물운송부문의 경쟁은 치열할 것으로 예상되는 반면, 국가 간 협력체제 구축도 필요한 시점이다. 지난 몇 년 동안 3국간은 협력체제 구축을 논의했지만, 가시적인 성과가 없는 현 시점에서 보면 보다 전향적인 발상을 기반으로 하는 접근방식이 필요할 것으로 판단된다. 역내운송의 완전 자유화 특히, 항공화물운송 자유화나 공항 운영 주체들 간 지역 내 제휴를 검토해 볼 필요가 있다. 이와 함께 중국, 일본 등의 공항과 항공화물 운송정보 공유, 기술개발과 표준화, 인적교류, 항공사 유치의 공동노력 등과 같은 제휴를 통해 역내 공항 네트워크를 구축하기 위한 방안은 반드시 협의되고, 추진될 필요가 있는 사안이다. 우리 내부적으로는 21세기를 대비한 보다 구체적이고 실천적인 항공화물운송부문의 ‘master plan' 수립과 함께 항공화물운송 주체인 항공사, 화주, 포워더 등 이용자 중심의 비용절감 방안과 항공화물 기반시설의 차질 없는 추진, 항공화물 정보화 등 편리하고 저렴한 운송체계와 처리절차를 수립이 요구된다.

It is important to compare the present condition of railway and marine freight transportation corridors to make good progress for freight transportation to the Eurasia region. This study is performed to investigate the current state of international corridors and to analyze mode choice characteristics between railway and marine transportation in the Eurasia region. SP (Stated Preference) data surveyed from international forwarders who are dealing with international freight shipment to the Eurasia area was used. The analysis results show that there is a competitive relationship between railway and marine transportation to Eurasia, and that the accessibility to each mode has an influence on freight mode choice. It is expected that this study will provide good insight to make effective use of various international corridors in the Eurasia region.

In recent years, due to the economic growth of the Northeast Asia, the trading relationship among the Asian countries becomes more active, and the mutual level of dependence is increasing. As the general market, the Northeast Asia pursue a function of market and economic activities among the Northeast Asia become more active consistently. It is important that Korea strengthened logistics network connection systems with China and Japan are improving the logistics facilities and expanding the transport network steadily. In order for Korea to improve as a logistics position, Korea needs to build various and efficient multimodal transport system and sets up a position as a major efficient logistics network center. Therefore, this paper intended to analyze transport cost and time of Korea-China-Japan logistics network and suggest a competitive multimodal transport with the maritime transport and new multimodal transport systems by comparing scenarios.

This research addresses the prospect of international intermodal transport in North-East Asia and studies the necessity of an agreement in transit transport in the region. Due to the division of labour among countries in the region and the globalization of firm's activities, international intermodal transport has been actively developed and is expected to grow continually. In order to lead the operation of international intermodal transport in North-East Asia, main players such as China and Russia have strengthened cooperation of regional logistics and made agreements in transit transport with contiguous countries. After analysing the current situation and reviewing prospects of international intermodal transport and transit transport in North-East Asia, this research proposes the requirement of regional agreement of transit transport on the basis of the United Nations Convention on the Law of the Sea (UNCLOS) for promoting international intermodal transport in North-East Asia.

1999년 8월에 발표된 "택시 타코미터 자료분석을 통한 운송수입금에 관한 연구"에 의하면 당시 택시 운행기록에 바탕을 두어 택시업체들의 지역적 입지를 고려한 표본을 추출하여 운송수입금과 관련하여 운행거리, 영업거리, 영업률의 요일별, 오전·오후별 분석을 실시하여 현실성을 충분히 감안한 연구가 이루어진바 있다. 그러나 본 연구에서는 좀더 정확한 운송수입금 분석을 위해 2000년에 택시조합과 협의하여 전년도 자료와 비교 분석하여 그 추이를 살피고, 지역별, 규모별 분석을 추가함으로써 현재 택시업계에서 가장 논란이 되고 있는 운송수입금 전액관리제에 대한 기초 연구 자료를 마련하고자 진행된 것이다. 분석대상은 서울시 전체 택시 업체 259개 중 10%가 넘는 31개 업체의 33,967개 일주일간 타코기록을 입력하여, 운송수입금, 운행거리, 주행거리, 영업률 등 4개 항목으로 나누어 연도별, 지역별, 규모별로 구분하여 각각을 분석하였다. 분석항목의 타당성을 검토하기 위하여 각각의 분석항목에 대한 분산분석(ANOVA)을 통해 평균치의 차이를 검정하였다 분석결과는 각 분석항목별로 요일별, 지역별, 규모별 차이는 거의 없는 것으로 나타났으나, 오전·오후간의 항목별 차이는 전년도와 마찬가지로 대부분의 항목에서 매우 큰 것으로 나타났다. 또한 전년도에 비해 운송수입금이 증가하여 운행거리, 영업거리, 영업률도 증가 추이를 보이는 것으로 나타났다.

This study shows how Incheon will advance into roadmap as multi-transport hub in Northeast Asia hereafter and be proposed an urgent tasks and roles to construct a multi-transportation system for Incheon, which has both an international airport and port. The multi-transportation point of view of inter-major cities competitiveness of total scores was proposed 1. Shanghai(64.8 points), 2 in Hongkong(64.5), 3 in Incheon(62.9), and 4 in Busan(60.4) and Incheon was estimated to have enough competitiveness to be the international multi-transport hub in Northeast Asia. Sea & Air transportation revealed the most important multi-transportation in the Incheon region. In conclusion, this research suggests a development plan for multi-transportation in Incheon. Firstly, it proposes construction of sea & air transportation distribution center and agreement that simplifies logistic process between Incheon and Tianjin, secondly, suggests to activate project for the purpose of creating a better sea-land transportation system between Incheon and Shanghai.

Most investment evaluations and economic assessments of road transport proposals in Korea omit a valuation of the time spent in transit for loads of freight. These days there were few attempts to estimate value of freight travel-time savings in Korea, but most of them included rail or marine with statewide area so that couldn't obtain unique travel-time savings for road freight transport. This study applied revealed Preference method and associated binominal logit models to estimate the value of travel-time savings in transit from an statewide survey of road freight transport in 1997. Data sets were segmented according to transport areas and business types. The results of this study showed that the value of freight travel-time savings varied wide ranges from 53,449 won per hour in urban transport to 29,397 won per hour in regional transport, that the use of statewide value of freight travel-time savings can drives wrong results into economic assessment, and that the use of adequate value of freight travel-time savings according to assessment area is very important.

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.
