최근의 코로나19 사태로 관광·항공업계가 극심한 어려움을 겪고 있다. 항공업계의 대안 중 하나는 화물운송이다. 항공사들은 여객수요 급감으로 인한 매출감소 폭을 줄이기 위하여 화물운송 부문을 강화하고 있다. 항공화물운송은 타 운송과 구분되는 제반 특성으로 인하여 시장규모가 지속적으로 증가하고 있다. 항공화물운송 대리점(forwarder)은 수출과 수입에 있어서 중요한 역할을 담당하며, 중요한 비즈니스 파트너인 항공사와 수출입자와 우호적인 긴밀한 관계를 구축하고 계속 유지해야 한다. 사회적 교환이론(social exchange theory)은 이러한 관계가 구축되기 위해서는 거래당사자 간의 거래규모나 거래기간, 거래빈도 등의 유형적인 측면도 중요하지만, 신뢰와 몰입, 애착 등의 무형적인 측면의 교환이 선행되어야 한다는 것을 강조한다. 본 연구의 연구목적은 다음과 같다. 첫째, 물류서비스기업의 업무 프로세스를 규명하고 운송기업 및 화주기업과의 사회적 교환행동은 어떻게 이루어지는지 조사한다. 둘째, 이러한 사회적 교환행동이 물류서비스기업의 다양한 경영성과에 얼마나 영향을 미치는지를 분석한다. 셋째, 각 구성원 간의 관계기간에 따라서 이러한 영향력이 달라지는지를 살펴본다. 특히 본 연구는 많은 기존연구에서 구분되었던 신뢰(trust)와 몰입(commitment) 개념을 통합함으로써 연구모형의 간결성(parsimony)과 실용가능성(practicality)을 제고하고자 한다. 결과적으로 본 연구는 운송기업 및 화주기업에 대한 물류서비스기업의 사회적 행동이 신뢰에 기반한 우호적인 관계를 구축하는지, 경영성과에는 어떤 영향을 미치는지를 실증적으로 살펴보고, 관계기간의 조절효과를 규명함으로써 학문적으로나 실무적으로 유용한 시사점을 제공할 수 있으며, 창업 물류서비스기업에 유용한 가이드라인을 제시할 수 있을 것이다.

Although Busan Port is a world-class transshipment port, it is geographically divided and, despite the continuous increase in transshipment volume, ITT port integrated operation is not being performed, reducing port operation efficiency. In addition, the operation raises the problem of inefficiency in social and economic aspects, along with an increase in the volume of transshipment transport and the resulting increase in transshipment transport costs. This paper deals with the necessity of forming an integrated operation organization to carry out the ITT joint dispatch in the process of improving the ITT efficiency in Busan Port, and the organization structure centering on the transport companies and freight owners performing the Busan Port ITT. We intend to make a proposal for the establishment of an integrated operation organization in the form of a consortium and support plans. In addition, through analysis of implications, the role of the ITT stakeholders in Busan Port and related organizations will be addressed.

This study was carried out to suggest new indicators to be used at airports. Generally, passengers and cargo will be handled at the airport, and the airport will achieve revenues through them. However, all airports can not have the same distribution of passenger and cargo throughput. When comparing and analyzing several airports, a uniform result can be expected only if a unit airport throughput indicator is applied. The 'Work Load Unit' is an indicator that integrates passengers and cargo into one, and assumes that the value of one passenger is equivalent to the cargo volume of 100kg. The existing WLU was set up based on the experience at the airport rather than being established through reasonable grounds or analysis, so there was a lot of controversy. The purpose of this study is to overcome these limitations and to suggest new index. In this study, we applied a method to compare the relative value of cargo and passenger to airport revenue. In order to analyze cargo value and passenger value, airport revenues are classified into aircraft operation related revenues, passenger handling related revenues, and commercial revenues. A total of 50 airports were selected, including 14 airports in Asia, 18 airports in Europe and 18 airports in North America. According to the final analysis results, it is concluded that the cargo is equivalent to 280kg of cargo based on the contribution of one passenger averagely. This is higher than the value of 100Kg cargo per passenger.

오늘날 날로 증가하는 물류비는 개별 기업은 물론 국가 전체의 수출 경쟁력을 약화시키는 주요 원인으로 지적되고 있다. 그러나 그동안 우리나라에서는 물류비 절감을 위한 종합적이고 체계적인 대책이 이루어지지 못하였다. 특히 본 논문의 연구대상인 육상물류의 경우 그 비중이 전체 화물 운송의 60% 이상을 차지함에도 불구하고 심각한 교통체증 및 물류기반 시설의 미비 등으로 인하여 물류비가 계속 증가하는 양상을 보여 왔다. 따라서 본 논문에서는 우리나라 육상물류시스템이 안고 있는 문제점의 해결을 위한 방안들 중의 하나로 정보기술의 활용에 관한 내용을 다루고 있다. 즉 영세한 기업들도 누구나 손쉽게 이용할 수 있도록 인터넷을 이용한 육상물류중개시스템의 개발에 관한 내용을 소개하고 있다. 육상물류중개시스템은 복합화물주선업체인 (주) 대형물류와 함께 개발한 시스템으로 인터넷을 통하여 화주의 화물 운송의뢰를 접수받아 이를 여러 운송업체에게 제공해 주는 역할을 수행하게 된다. 특히 육상물류중개시스템은 화물의 운송과 관련하여 발생하는 다양한 정보들을 데이터베이스에 저장하여 두었다가 세관을 비롯한 터미널에 대한 각종 신고업무에 이용할 수 있으며, 이밖에도 교통정보 및 화물 위치정보 등 다양한 서비스를 제공해 줄 수 있다. 따라서 운송업체의 공차율을 줄이고 화주에게는 자신의 화물에 대한 정보를 실 시간으로 전달해 줄 수 있다는 장점이 있다. 또한 이러한 육상물류중개시스템은 현재 개발중인 통합데이터베이스를 기반으로한 항만물류원스톱서비스 시스템과 연계되어 차후에는 물류원스톱시스템으로 발전할 수 있을 것이다.용되어져 왔다. 그러나 MCRDR 이론이 적용된 전문가시스템들의 경우 MCRDR이론을 기본으로한 개발 툴로서 개발된 시스템들이 아니고 해당분야에서 MCRDR이론을 적용한 엔진을 직접 설계 구현하여 온 것이 사실이다. KEE(Knowledge Engineer for Experts) 시스템은 최근 개발된 MCRDR기반 전문가시스템 개발 툴로서 본 논문에서는 이러한 분야별 전문가시스템 개발을 지양하고 MCRDR 이론을 기반으로 한 범용성 있는 전문가시스템 개발 툴의 개발에 관한 연구를 소개한다.-based Data Mining Architecture를 제시하였다. 본 연구의 의의로는 데이터 마이닝을 통한 귀납적 지식생성에 있어 귀납적 오류의 발생을 도메인 지식을 통해 설명가능 함을 보임으로 검증하고 아울러 이러한 설명을 통해 연역적으로 새로운 가설지식을 생성시켜 이를 가설검증방식으로 검증함으로써 귀납적 접근과 연역적 접근의 통합 데이터 마이닝 접근을 제시하였다는데 있다.osed algorithm are faster and lower than the existing LMS according to increasing the step-size parameter $\mu$ in the experimentally computed. learning curve.

The pallet, typically a form of tertiary packaging, is a flat structure used as a base for the unitization of goods in the supply chain. In addition, standard pallets such as T-11 and T-12 are used throughout the logistics industry to reduce the cost and enhance the efficiency of transportation. However, in the case of special cargo, it is impossible to handle such cargo using a standard pallet due to its size and weight, so many have developed and are now using their customized pallet. Therefore, this study suggests a pallet size optimization method to calculate the optimal pallet size, which minimizes the loss of space on a pallet. The main input features are the specifications and the storage quantity of each cargo, and the optimization method that has modified the Neighborhood Search Algorithm calculates the optimal pallet size. In order to verify the optimality of the developed algorithm, a comparative analysis has been conducted through simulation.

As competition in domestic and overseas ports intensify, new and small domestic ports are realizing certain limitations to independently secure competitiveness. This study collected data over 60 months with five modifications for container and general cargo volume around Gyeongin Port. Short-period (12 months) cargo volume was forecasted, which revealed the need for a middle-to-long-term development plan. First, the hinterland logistics complex of Gyeongin Port is expected to contribute to the coastal maritime facility through the quasi-public system for fishery product transportation and passenger services. It proposes to achieve this by opening channels to and from China for precision machinery, home network systems, LEDs, and machine industry items. second, specializing the ultra-light cargo transport route, and connecting the coastal island areas of the 5 West Sea Islands to Ara Waterway (Integrated Fishery Product Center of the 5 West Sea Islands). Third, on the basis of organic cooperation of government? local government ? port, the incentive and pre-circular support system would be required, and lastly, it shall carry out the adjustment of functions in nearby ports and specialization strategy simultaneously through the integrated operation of the ports in the capital areas.
