In this regard, the newly focused logistics information system makes reducing the expenses of whole logistic available by cutting down the expenses of materials, transportation and stock and also, it allows the company to cut down the procurement expense through the reduced lead-time and rationalize producing plans by eliminating the uncertain orders and fluctuation in procurement. It further more optimizes the efficiency of over all productions by meeting the dead line for delivery to the customers. In the recent environment of globalization where fierce competitions exist between manufacturers, logistics plays important role in the strategies of companies, and managements of companies try their best efforts in establishing the strategy to accomplish the innovative relationship between supply chain channels. Therefore, in this study, we try to suggest the model of consolidated logistics system that is integrated logistics information system with suggesting the better way of logistics and comparative analysis with logistics system to resolve the difficulties numbers of companies face after realizing what logistics information system is in Korea.

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.

Today, with the development of the Internet and mobile technology, consumers' purchasing patterns have shifted from offline to online. In addition, due to the recent COVID-19, online purchases have significantly increased, and accordingly, the courier industry for logistics delivery has also grown significantly. Various logistics robots are being operated in many industrial and can reduce the labor intensity and physical and mental fatigue of workers. However, if the logistics robot does not properly recognize the people or environment around it, it can lead to a serious accident. We conducted that how logistics robots can perform safe work in a working environment such as a logistics warehouse through the application of ISO/DIS 21448 (SOTIF) to autonomous logistics transport robots. This result is expected to contribute to the operation of unmanned logistics warehouses using AGV.

창고형 매장의 성장이 가속화되면서 창고형 매장에 대한 물류의 중요성도 증대되고 있다. 이러한 측면에서 본 연구는 GIS를 사용하여 C사의 Depot 통합운영 후 운송 효율성을 분석하였다. Depot 통합에 따른 컨테이너 출고 물동량 변화를 분석한 결과, 배송시간 측면에서는 Depot 1개를 운영 할 경우 연간 총 1,028,699km 운행이 필요한 것으로 분석되었고, 이는 Depot 3개를 운영할 때 연간 총 2,866,604km 운행이 필요한 상황과 비교할 경우, 연간 1,028,699km 감소가 되는 것을 확인할 수 있다. 배송시간 측면에서도 Depot 1개를 운영 할 경우 일일 62시간의 시간절감과 전체적으로 36%의 절감효과를 기대할 수 있었다. 본 연구는 GIS OD Matrix를 이용하여 Depot 통합과 컨테이너 배송전환에 따른 운영 프로세스 개선, 운송시간 및 거리 절감효과를 제시하였다. 본 연구의 결과는 다른 창고형 할인매장의 배송 프로세스에 영향을 줄 수 있는 중요한 판단지표로 활용될 수 있다.

In this paper, we develop a planning system for the routing and scheduling of vehicles in pickup and delivery service such as door-to-door parcel service. Efficient routing and scheduling of vehicles is very important in pickup and delivery service. The routing and scheduling problem is a variation of vehicle routing problem which has various realistic constraints. We develop a heuristic algorithm based on tabu search to solve the routing and scheduling problem. We develop a routing and scheduling system installed the algorithm as a planning engine. The system manage the basic data and uses GIS data to make a realistic route plan.

The logistics market is continuously growing due to the development of technology and the growth of the online market. In addition, the social atmosphere that emphasizes non-face-to-face due to the pandemic situation is accelerating the growth of logistics. Delivery of goods ordered online requires delivery process through courier worker. In order for the courier worker to ship the product, the work of loading the product on the truck must be preceded. The accident caused by such delivery and loading work is increasing and it is emerging as a social problem. This study proposes a robot-based automated loading system to efficiently handle the increasing volume of courier service and to construct a more efficient and safe working environment by replacing the physical labor that was overloaded to courier workers. The proposed system replaces the loading of the courier worker and proposes the optimal loading function through the automation system.

중국경제의 급성장으로 인하여 아시아 물류수요가 급격히 증가하고 있다. 따라서 각 국은 이러한 수요를 유치하기 위한 항만개발에 전력을 투구하고 있다. 우리나라도 부산항${\cdot}$광양항을 중심으로 환적항, 나아가서 동북아 물류 중심국가가 되기 위한 여건을 마련하고, 적극적으로 항만마케팅에 나서기 시작했다. 최근 일본은 물류비용의 증대로 항만경쟁력이 감소하여 그에 대한 다양한 방안을 강구하고 있다. 이러한 일본의 침체환경을 기회로 활용하여 부산항${\cdot}$광양항의 활성화로 연계할 수 있는 노력이 필요하다. 따라서 본 연구는 일본의 수출입화물의 배송루트를 유형별 즉 기존의 일본 주요 항을 이용하는 경우와 부산항${\cdot}$광양항을 이용하는 경우로 구분하여 소요되는 물류비용을 산정하였다. 그 결과 부산항${\cdot}$광양항을 경유하는 경우가 훨씬 큰 물류비용의 절감효과가 있는 것으로 나타났다.

Recently, consumers who prefer contactless consumption are increasing due to pandemic trends such as Corona 19. This is the driving force for developing the last mile-based logistics ecosystem centered on the online e-commerce market. Lastmile led to the continued development of the logistics industry, but increased the amount of cargo in urban area, and caused social problems such as overcrowding of logistics. The courier service in the logistics base area utilizes the process of visiting the delivery site directly because the courier must precede the loading work of the cargo in the truck for the delivery of the ordered product. Currently, it's carried out as automated logistics equipment such as conveyor belt in unloading or classification stage, but the automation system isn't applied, so the work efficiency is decreasing and the intensity of the courier worker's labor is increased. In particular, small-scale courier workers belonging to the sub-terminal unload at night at underdeveloped facilities outside the city center. Therefore, the productivity of the work is lowered and the risk of safety accidents is exposed, so robot-based loading technology is needed. In this paper, we have derived the top-level concept and requirements of robot-based loading system to increase the flexibility of logistics processing and to ensure the safety of courier drivers. We defined algorithms and motion concepts to increase the cargo loading efficiency of logistics sub-terminals through the requirements of end effector technology, which is important among concepts. Finally, the control technique was proposed to determine and position the load for design input development of the automatic conveyor system.

At present, on increasing to use a computer network and internet network, Internet Trade has been rapidly created and developed in international Electronic Commerce. However, Internet Trade has not been continued to grow up without supporting by a efficient Logistics System. Because it is very important to delivery contract commodities to consumer with speedy, accurate, steady, convenient services. International Logistics System is consisted of demand forecasting, order processing, packing, labeling, shipping documentation and consumer service into three distant phases of transaction, distribution and payment. International Logistics System can be done more efficiently and effectively by using Internet Logistics System. Therefore it is very important to implementing a efficient Internet Logistics System.
