A cold storage is a warehouse of a insulated building with cooling installations. It has many different types of cold rooms with temperatures below 0 degrees Celsius, and the sequential workflow such as receiving, picking and packing runs in that rooms. Recently, the cold storages have adopted RFID technology, and consequently, warehouse product management in them are becoming intelligent and network. However, information inconsistency in warehouses caused by physical and logical errors reduces reliability in the RFID cold storage management system and worsens their work efficiency. Therefore, it is necessary to develop an early detection system to identify errors. In this paper, we suggest a supervisory system detecting logical errors on business processes of the RFID cold storage. It is composed of a master supervisor and mobile supervisor. In the master supervisor, the manager can set the constraints conditions and get alerts, and in the mobile supervisor, the workers confirm and deal with these faults directly. The supervisory system improve reliability of the RFID cold storage management system by recognizing a failure to identify physically and logically using these constraint conditions. This paper shows that the supervisory system can reduce the average recovery time to improve reliability by decreasing the time for detecting and analyzing errors in the RFID cold storage management system.

2014년 우리나라 선용품 시장의 규모는 5조 7천400억 원 정도로 추정된다. 대부분이 부산, 울산 등 부산권에서 이뤄지지만 관련업체가 400여 개나 난립해 대부분 평균 매출이 20여억 원으로 영세한 수준이다. 또한 세계 해운항만산업의 불황과 중국을 비롯한 개발도상국들의 저가 선용품의 생산 및 공급으로 인해 국내 선용품 업계가 그다지 밝지 않는 상황이다. 이렇듯 영세한 선용품 산업을 발전시키기 위해서 부산시에서는 부산항국제선용품유통센터 내에 공동물류(창고)를 운영을 제시하였으며 이를 세부적으로 파악하기 위해 성공적 방안 요인 16개의 도출하여 AHP와 IP분석을 사용하여 전략적 방안을 제시하였다.${\cdots}$ (중략) ${\cdots}$.

오늘날 컴퓨터 및 통신 기술의 급속한 발달로 인해 디지털 시대가 도래 하면서 전자 서비스가 보급 되었지만 전자 출력물들은 프린터로 출력하여 문서 창고 안에 보관되어 문서의 진위 여부 확인이나 법적인 문제가 발생시에 종이 문서 창고에 의지할 수 밖에 없었다. 이렇게 창고 안에 보관하는 것도 문서의 양이 비약적으로 많아져 운영하는데 막대한 비용이 발생되고 있다. 한편 기존 문서를 전자문서로 변환하면서 데이터 누락되거나 데이터가 변질되거나 유실되는 문제가 빈번하게 발생되었다. 본 논문에서는 기존 문서를 전자 문서로 변환하고, 이후 문서 수정이 발생할 때에는 버전 관리를 통해 안정성을 높인 워터마크와 OCR 기술을 적용한 전자 캐비닛 시스템을 설계 구현한다.

The agricultural industry in Lam Dong Province has been growing in volume and kinds of produces. Various vegetables, fruits, flowers and coffee are the characteristics of the agriculture industry in Lam Dong. This situation makes the necessity of chilled and cold storages with commercial capacity. Another factor in Lam Dong is that there are more than 70 quarries under operation or abandoned. Upon the MOU between Lam Dong Government, BCMP and RIGPE, BCMP and RIGPE carried out the prefeasibility study on the construction of the underground cold storages using abandoned quarries in the Lam Dong area. They submitted the final report of the prefeasibility to the Lam Dong Government in August, 2018. In this report, the overall summary of the prefeasibility of the underground cold storage in Lam Dong is presented.

By strengthening the market control and expanding the networks, providers of global logistics are expanding their service scope. The warehouses connect networks to internal and external warehouses by using logistics providers. The paper focuses on analyzing the efficiency of warehouses on each district. Therefore, the study classifies the factors which specify the efficiency of a total logistics of warehouse industry and warehouses' employees and the number of warehouses on district. Furthermore, the most recently published reports by National Center for Statistics in 2012 was used in order to guarantee credibility of the study. This study utilizes five years of materials, which are from 2005 to 2009. By applying SBM (Slack Based Measure), DEA Window model, and the Malmquist productivity model, the trend in efficiency and stableness were analyzed. The principal purpose of the paper is evaluating the efficiency. Also, analyzing its determinants and illustrating a long-term relationship between the regional warehouses and annual turnover of the warehouses were used as output measures. In addition, the number of warehouses of each region, employees, warehouses equipments, and the Logistics Warehouses Providers were used as input measurements. As a result, Malmquist productivity model and annual stableness has shown a continuous increasing. Ultimately, to be approved as product of Korea, a new stratiges that meet the standards and Rules of Origins by FTA should be developed. Therefore, there must be a development that takes regional characteristics into consideration.

한국통합 물류협회에 따르면 총 택배 물량은 2020년은 약34억 개, 2021년은 약36억 만 개로 매년 꾸준히 성장하였다. 택배 물류센터에서 택배를 고객에게 전달시키기 위해서는 포장, 검수, 진열, 파지, 상차, 하차 등 많은 공정이 필요하다. 고용 인력의 부족, 인건비 상승, 부상의 위험, 높은 노동의 강도 등의 문제가 발생하였고, 소비자들의 입장에서도 제품 손상 또는 배송 지연 등의 여러 가지 문제를 야기해왔다. 본 논문은 로봇과 자율주행 기술을 활용하여 상품의 분류 및 배송과정을 자동화 하는 '스마트 물류창고 시스템'을 제안한다. 컨베이어 벨트를 이용해 택배물품의 분류를 자동화하고 자율주행 차량을 통해 배송을 하게 되고 DB를 통해 물품을 관리하게 되어 효율적인 운영을 가능하게 하고 경제적 손실을 줄인다. 적외선 센서, 바코드 센서를 이용해 컨베이어 벨트 구동 및 물품의 정보를 알 수 있으며 서보모터로 물품을 분류한다. 또한 입출고 차량이 명령을 통해 물품을 자동으로 입고 및 출고하여 DB에게 물품의 정보를 전송한다. 스마트 물류창고 시스템을 통해 인건비 절감, 오 배송, 물품 파손 등이 사라지게 되고 물류창고 뿐만 아니라 다양한 분야에서 적용 할 수 있을 것이다.

It it essential to get the exact location information of products for a warehouse management. It is very hard, however, to know the location of products which change their location in warehouse frequently This causes the effective warehouse management to be almost impossible. In this paper, we suggest a new location management system for such a SKU(Stock Keeping Unit) with high mobility. The system is composed of RFID (Radio Frequency IDentification), a management terminal with wireless LAN, mobile devices (Cellular Phone & PDA), and a central management system. As a model of a SKU with high mobility, we selected a used-car stored in a large-scale warehouse. We designed and implanted used-car location management system. After analyzing the operations of each position in used-car warehouse where the system will run, we implemented each function. This research shows that an embedded system with wireless LAN is able to know the status of coming in and cut and location of a SKU with high mobility in warehouse very accurately in real time. Therefore, it makes the warehouse to be controlled systematically.

Purpose: The purpose of study was to identify problems in disaster recovery resource management and operation through on-site investigation and utilize them as improvement proposal for disaster recovery resources management by local governments. Method: Areas with high natural and social disasters recorded in historical and yearly records of natural and social disasters, related books, and annual reports for 20 years were selected. The DRSS data of the selected local governments were analyzed and the reserve warehouse were selected for field survey. Result: It is analyzed that the current situation in the city hall and district offices is somewhat insufficient due to heavy work by the working-level officials of local governments on the storage of disaster recovery resources. The actual amount of stockpiles and DRSS data are somewhat different or missing because the input method and criteria are not clear at present when inputting the current data. Conclusion: To improve the management of the disaster recovery resource reserve, it is deemed that education of DRSS and training of best practices for the operation of disaster management resources are urgently needed, and that a systematic management of stockpiles using disaster prevention experts will be required.

As the growth of warehouse stores has been accelerated, the importance of logistics for warehouse stores has been also increasing. In this respect, this study analyzed the transportation efficiency after the integrated operation of depots by C Company using GIS. According to the results of analysis of changes in container shipment cargo volumes, in terms of delivery distances, a total of 1,028,699 km of delivery car driving was shown to be necessary when one depot was operated, while a total of 2,866,604km of car driving was shown to be necessary so that 1,028,699km of car driving was reduced per year. In terms of delivery time too, 62 hours of time was saved per day and a total of 36% reduction in time could be expected. This study presented the effects of depot integration and delivery changes to improve operation processes and reduce delivery time and distances using GIS OD Matrix. The results of this study can be used as an important indicator for judgment that can affect the delivery process of other warehouse discount stores.
