택배물류는 택배화물을 택배서비스 요청자가 요구하는 장소까지 직접 배달해 주는 것으로, 택배 기업별로 화물 분류 방식, 업무방식, 그리고 관리하는 정보가 서로 다르고, 비정형 데이터로 인해 상호 호환성을 지원할 수 없다. 종이 운송장 사용으로 개인정보 유출에 대한 문제와 오류 정보로 인해 정확히 화물은 전달하는데 추가적인 시간과 물류비용이 발생되기도 한다. 택배 비즈니스 환경은 무인택배, 신기술(사물인터넷 등)이 도입되는 등 변화되며, 사용자들은 택배 운송 신청부터 수취까지의 과정에 대한 현황 및 상태를 알고 싶어 한다. 그러므로 택배화물 안전 배송을 위한 단일화되고 통합된 운송장 정보가 필요하며, 택배화물 집하/운송/인도 등의 단계에서 적합한 정보를 관련 주체 간에 원활히 제공되어야 한다. 본 논문에서는 택배화물 운송서비스 신청, 집하, 운송, 분류, 인도 등의 단계별 정보를 수집, 가공, 처리한 정보를 비즈니스 처리, 비즈니스 협업, 비즈니스 트랜잭션 간에 발생하는 업무 흐름에 대한 정보로 명시하고 이 정보를 근간으로 택배화물용 전자 운송장을 위한 표준 프로세스와 정보 모델을 정의하였다. 정의된 표준 모델을 통해 택배물류 주체 간 정보 유통 및 공유가 용이할 것이며, 종이 운송장으로 인한 위험이 감소됨으로 인해 국민생활 안전을 증진할 수 있게 될 것이다. 더 나아가 택배업체의 업무 효율성이 증대되는 등 다양한 이해당사자 관점에서 국민 편익을 도모할 수 있을 것으로 판단된다.

The drone serves the customers not served by vans. At the same time, considering the safety, policy and terrain as well as the need to replace the battery, the drone needs to be transported by truck to the identified station along with the parcel. From each such station, the drone serves a subset of customers according to a direct assignment pattern, i.e., every time the drone is launched, it serves one demand node and returns to the station to collect another parcel. Similarly, the truck is used to transport the drone and cargo between stations. This is somewhat different from the research of other scholars. In terms of the joint distribution of the drone and road vehicle, most scholars will choose the combination of two transportation tools, while we use three. The drone and vans are responsible for distribution services, and the trucks are responsible for transporting the goods and drone to the station. The goal is to optimize the total delivery cost which includes the transportation costs for the vans and the delivery cost for the drone. A fixed cost is also considered for each drone parking site corresponding to the cost of positioning the drone and using the drone station. A discrete optimization model is presented for the problem in addition to a two-phase heuristic algorithm. The results of a series of computational tests performed to assess the applicability of the model and the efficiency of the heuristic are reported. The results obtained show that nearly 10% of the cost can be saved by combining the traditional delivery mode with the use of a drone and drone stations.

본 논문에서는 Visual 동시적 위치추정 및 지도작성(SLAM : Simultaneous Localization and Mapping)기술을 응용하여 실내에서 생성된 SLAM 맵을 기반으로 지정된 목적지에 물건을 배달하는 자율주행 차량 플랫폼을 제안하였다. 실내에서 SLAM 맵을 생성하기 위해 소형 자율주행 차량 플랫폼의 상단에 SLAM 맵 생성을 위한 심도 카메라를 설치하고 SLAM 맵 속에서의 정확한 위치추정을 하기 위해 추적 카메라를 장착하여 구현하였다. 또한, 목적지의 표찰을 인식하기 위해 합성곱 신경망(CNN : Convolutional neural network)을 사용하여 목적지에 정확하게 도착할 수 있도록 주행 알고리즘을 적용하여 설계하였다. 실내 배송 자율주행 차량을 실제로 제작하였고 SLAM 맵의 정확도 확인과 CNN을 통한 목적지 표찰 인식 실험을 수행하였다. 결과적으로 표찰 인식의 성공률을 향상시켜 구현한 실내 배송용 자율주행 차량의 활용 적합성 여부를 확인하였다.

The main issue relating to electronic bill of lading is to develop the system in which can transfer the title to the goods by electronically, and to support effect of electronic transfer of title by law. BBL, electronic bill of lading being operated by bolero, provides technical devices to that purpose, but current law is not recognize the effect of transfer of title by electronic communication because BBL is different from paper bill of lading naturally. For that reason Bolero has resolved the problem by Rulebook which is multilateral agreement contracted between users and BAL. The Rulebook provides solution, so called, 'attornment' and 'novation'. So, The purpose of this study is to help in understanding BBL through comparison and analysis about the legal background of transfer of title by BBL based on 'attornment' and 'novation' with transfer of bill of lading based on a endorsement and delivery.

As we know, Incoterms are reflecting only the greatest common measure of practice in int'l trade. Therefore we can think them as the commercial practice most widely used in trade. They contain a number of detail under converse mirror image terms because they connect each other like a thread as to all oversea's commercial transactions between importing buyers and exporting sellers. Therefore they afford convenience to exporters and importers in the world because they tell the parties what to do as to transfer of risk and costs, responsibilities in connection with delivery of the goods. Nonetheless, since Incoterms 1936, they have been periodically revising in order to represent contemporary commercial practice. Therefore, according to change of Int'l trade environment, ICC plans to modify to the 2000 Incoterms. I hope to contribute to revising works by reference of above mentioned revision, that to say, aspects of provision, reflection of prevailing most commonly used, promotion of status as uniform rules, provision of convenience of int'l buyers and sellers. harmony with existing int'l instruments, presentation of criteria in variation of Incoterms.

Reverse logistics is the process of planning and controlling the recovery flow of end of life products. Industry is increasingly being confronted with the need to solve several reverse logistics issues because of not only stringent environmental legislations but also economic reasons. Recently, thanks to the advent of emerging technologies, such as RFID, enhancing the productivity of reverse logistics operations has been highlighted. The application of RFID technology is going beyond forward logistics, which is the delivery of manufactured goods to consumers, and being expanded, though not frequently yet, to reverse logistics, which includes return, recovery, reuse, reproduction and disposal. However, it requires a deep insight for the research of reverse logistics and new environment. In this regard, we studied effectiveness by applying RFID middleware technology to reverse logistics.

In the form of B2C transaction, making an on-line order by using the website increases rapidly. An off-line order at the whole sale outlets is geometrically increasing. However, it is so true that both types of market are showing a tendency to become computerization. As to apply this type of computerized B2B transaction to this kind of large scale wholesale outlets, the most important fact to be considered is that there must have no data error. In addition to this, an accurate counting of actual stock is a precondition to decide a suitable amount of production and a timely delivery of goods. In this study, reducing elements of the risk that may create a difference In between actual stock and that in the computer, the integrated B2B ordering system is designed by taking actual cases an example in order to manage the information for a sale, which is conducted by various system in the large scale wholesale outlets such as E-mart, Carefour or the same kinds.

Unmanned aerial vehicles are gaining in popularity with the development of science and technology, and are being used for a wide range of purposes, including surveillance, rescue, delivery of goods, and data collection. In particular, the ability to avoid obstacles during navigation without human oversight is one of the essential capabilities that a drone must possess. Many works currently have solved this problem by implementing deep reinforcement learning (DRL) model. The essential core of a DRL model is reward function. Therefore, this paper proposes a new reward function with appropriate action space and employs dueling double deep Q-Networks to train a drone to navigate in indoor environment without collision.

Recently, many new constructuion and large scale modification of railway are performed for cost down of goods delivery charge and effective transportation in various aspect. Although railway traffic is environmentally frendly in many part but weak in noise and vibration problem. For the reduction and efficient management of railway noise, first of all prediction of railway noise is necessarily requisted. In domestic and abroad many studies for prediction of railway nearby noise are done. In this study simple modelling technique is investigated for railway noise prediction when railway passes above elevated concrete bridge as well as ground. Predicted results are compared with measured results and it is known that suggested modelling technique can be used for more precise prediction of railway nearby noise.
