Foreign countries stipulate that ventilation and smoke control facilities are installed in logistics warehouses. On the other hand, in Korea, the design guidelines and standards of ventilation and smoke control facilities for logistics warehouses are not clear even in the situation where the number of human casualties caused by smoke has increased until recently. Accordingly, the smoke descent time according to the vent was calculated. As a result, when there was no vent, the smoke descent time was 369s. On the other hand, when the vent was installed, smoke did not fall because the amount of smoke was greater than the amount of smoke generated.

The importance of logistics of warehouse stores has increased as their prices are cheaper and more convenient than those of large supermarkets. However, few studies on integrated depot location selection of warehouse stores have been conducted. In this regard, this study aims to derive factors for integrated depot location selection and calculate weights and select the location priority of target candidates by introducing an analytic hierarchy process (AHP). The analysis results exhibited that the most important selection factor was the cost reduction in transportation and delivery (0.198) followed by distance reduction in transportation and delivery (0.168), and time reduction in transportation. This study quantified the reduction in cost and increase in efficiency if depots were integrated and operated thereby presenting more realistic foundational data to hands-on workers. For the future study, the analysis model will be needed to be advanced through additional investigation on the factors in the analysis.

This study investigates the strategies that are important for selecting shuttle carriers and logistics warehouses. In container transportation, competitive pricing has become an order qualifier due to the establishment of the standard freight rate system. As a result of this study, it can be seen that both logistics warehouses and shuttle carriers place greater importance on the partnerships with companies and employee education. Besides those two factors, the punctuality of delivery is found to be important for the quality of transportation. Therefore, companies must continue to increase their competitiveness. As customer service of the shuttle carrier, resolving the loss or damage and claim handling part is evaluated more importantly in the logistics warehouse than the ablity to resolve unexpected event. The future strategy should focus on resolving the loss/damage and claim handling factors so that companies can be competitve in the future. Based on research results, logistics warehouses and shuttle carriers can establish different marketing strategies to maintain a firm position on the market by securing competitive advantage within port hinterland.

In a warehouse, because there exist frequent changes of stock status and the quality of some contents are influenced by the environment such as temperature, fast and accurate management of the warehouse's environment is very important for Warehouse Management Systems. However, due to the absence of a unified standard for the communication protocol between RFID nodes and centralized MAC schemes for RFID communications in previous studies have severe problems. Therefore, in this paper, we propose a WiMedia MAC based RFID cooperative relay transmission scheme for warehouse management system applications.

When a fire breaks out in a distribution center, it causes a lot of damage. And the most casualties are caused by Fire accidents. Therefore, training for fire prevention should be mandatory at the distribution center. Also, the contents of education should be different in room temperature warehouses and low temperature warehouses. Fire education in low-temperature warehouses should be more emphasized. This is because many fires occur in low-temperature warehouses. In this study, a study was conducted to determine the important order of training hours and contents for fire prevention education according to the type of distribution center. The importance of time and content for safety education in all types of warehouses did not differ significantly. It was first decided that safety prevention training should be conducted periodically in all types of warehouses

Purpose: The purpose of this study is to present the commodity classification method of domestic rack-type warehouse for sprinkler system design. Method: On-site surveys and classification criteria of the NFPA, FMDS, EN and Japan were analysed and ISO 12949 test were carried out with proposed each classification commodity. Result: Based on a heat of combustion, a classification method for extra high, high, medium and low are proposed. Conclusion: Sprinkler design criteria to secure the maximum extinguishing strength for each class of commodity need to be applied.

최근 들어 단순 보관의 기능만을 가지고 있던 기존의 냉동창고가 보관뿐만 아니라, 규격화된 유통시스템을 갖추어 전체 물류 공급망 관리의 효율성과 경쟁력을 갖추고자 한다. 이를 위해 라디오 주파수를 이용하여 움직이는 물체를 인식, 추적, 분류할 수 있는 기술인 RFID (Radio Frequency Identification)를 적용할 수 있다. 그러나 RFID 기술을 도입하기 위해서는 여러 시나리오를 통해 최적의 실행 방안을 도출해 내야하며, 이를 바탕으로 자동화 프로세스를 지원해 줄 수 있는 RFID 애플리케이션을 개발할 수 있다. 본 논문에서는 RFID 기술을 적용하여 최적화된 비즈니스 프로세스를 지원하는 냉동창고 관리 시스템을 개발하고자 한다. 이를 위해 냉동창고 업무 프로세스를 분석하고 RFID 기술 도입에 따른 의사 결정이 필요한 설계요소들을 식별한다. 식별된 설계요소들은 RFID 배치 시뮬레이터를 이용하여 RFID 데이터가 비즈니스 프로세스에 통합되는 과정에 대하여 그 효율성을 판단할 수 있게 한다.

The trade volume of Northeast Asian countries is increasing and with the advent of the 4th revolutionary era, minimizing the logistics costs of firm is becoming an important competitive factor. With respect to this, in 2006, the government introduced a certified Integrated logistics firm system to improve the competitiveness of local logistics firms and reduce the logistics costs of firms. They argued that the certified Integrated logistics firm system increased the reliability of logistics firms and increased the efficiency of the logistics industry. On the other side, they argue that the system puts a burden on firms and becomes a big business-oriented market consolidation. This study analyzed the efficiency of Warehousing firms using DEA model. The CCR, BBC efficiency and RTS (return to scale) of 15 Warehousing firms were evaluated. This study also suggested the Warehousing firms which can be benchmarked based on analyzed information.

In rack-type warehouses, it is difficult to extinguish fires effectively using sprinkler systems because high fire load commodities are stacked vertically and densely. In this study, an actual size rack structure was constructed and the effectiveness of the fire extinguished by the sprinkler system was confirmed through fire tests according to the type and arrangement of the sprinkler head in the rack structure. Through this study, to effectively suppress fires in rack-type warehouses, it is necessary to use sprinkler heads with a volume of more than 115 LPM and sprinkler heads need to be installed at the diagonal corner positions of the commodities of each rack.
