Purpose: Fires that occur during construction are infrequent, but cause great damage. Recently, with the growth of the logistics and distribution industry, the number of construction sites for new logistics warehouses is increasing, so it was selected as a research subject and research was conducted to reduce accidents at construction sites through the development of a fire risk assessment tool to quantitatively approach fire prevention. Method: A comprehensive fire risk assessment tool was accumulated by classifying the work in progress, classifying combustibles and ignition sources by grade, excluding air (oxygen), which is difficult to control, and additionally substituting evacuation safety. Result: Using the developed and proposed fire risk evaluation tool, excavation work with low fire risk, facility construction with medium fire risk, and finishing work with high fire risk were sampled to derive the result (CGI). Conclusion: In this study, it was possible to establish specific preventive measures and evaluate evacuation safety by controlling physical conditions (combustibles) and energy conditions (ignition sources) according to the risk assessment by developing a tool that can evaluate the risk of 14fire occurrence at construction sites. It is expected that in the future, through the application of the fire risk evaluation tool at construction sites, it will be provided as a criterion for establishing a process plan that can reduce risk and evaluating the adaptability of firefighting equipment.14

Logistics optimization problems related with vehicle routing such as warehouse locating, track scheduling, customer order delivery, wastage pickup etc. are very interesting and important issues to date. Many Vehicle Routing and Scheduling Systems (VRSS) have been developed/proposed to optimize the logistics problems. But majority of them are dedicated to a particular problem and are unable to handle the real world spatial data directly. The system developed for one problem may not be suitable for others due to inter-problem constraint variations. The constraints may include geographical, environmental and road traffic nature of the working region along with other constraints related with the problem. So the developer always needs to modify the original routing algorithm in order to fulfill the purpose. In our study, we propose a general-purpose platform by combining GIS road map and Database Management System (DBMS), so that VRSS can interact with real world spatial data directly to solve different kinds of vehicle routing problems. Using the features of our developed system, the developer can frequently modify the existing algorithm or create a new one to serve the purpose.

물류 표준화의 핵심은 수송, 보관, 포장, 상/하역, 정보/보안의 물류활동간의 호환성과 연계성의 확보이다. 국제표준 채택을 의무화하고 있는 WTO/TBT 협정을 차치하더라도 물류표준화의 정도는 국가의 물류경쟁력을 결정짓는 가장 중요한 척도라고 할 수 있다. 특히 한 중 일 3국의 경우 교역랑만 5조 3,236억불로 전 세계 교역량의 17.6%(2010년 기준), GDP 합계 12조3443억 달러로(2010년 기준) 세계전체 GDP 62조 9093억 달러 중 19.6%, 해운물동량은 전 세계 물동량의 60% 이상을 차지하고 있는 상황에서 물류경쟁력은 곧 국가경쟁력으로 보아도 무방하다. 아직도 국내에서는 물류분야 간 연계와 첨단정보기술이 결합된 현장중심의 융 복합 표준이 미비하고 대부분의 경우 해외국가들이 자신들의 입장대로 추진하거나 선점한 표준을 따라가기 바쁜 실정이었다. 스마트물류표준화는 이러한 현실에서 탈피하여 글로벌 물류표준을 선도하고 국내 현실에 적합한 현장물류표준을 반영하자는 취지에서 출발한다. 스마트물류는 i-ULS(Intelligent-Unified Logistics System) 체계, 즉 IT와 각 물류기술을 융합하여 표준화시키는 것은 물론 기존 표준을 산업현실에 맞게 반영해 나가는 것이 국가표준코디네이터로서의 주요한 목표가 되고 있다. 본 고는 전년도 스마트물류 표준화로드업에 작성된 표준화기술 중 산업체 설문을 통하여 10대 주요 표준화 트렌드를 선정하여 정리한 것이다. 10대 표준화 기술로는 순환물류포장시스템, 실시간 위치추적기술, 스마트컨테이너(Smart Freight Containers), 해상용 컨테이너 모니터링 시스템(CTMS), 글로벌 포장 표준모듈, 친환경물류 표준지표, 스마트물류 포장용기, 스마트그린물류센터(Passive Warehouse), 모바일 RFID 물류 적용 기술, Modal Shift(전환교통) 등이 선정되었다. 이번 4월호 특집에서는 10대 표준화 전략트렌드 가운데, 스마트물류에 대해 알아보도록 한다.

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 the paper, we design a autonomous mobile robot for freight transportation and propose an operation method of the robot in the warehouse. In order to implement autonomous navigation, it is needed to recognize the position of the robot and track the path to the target. Previous methods are hard to change the workspace environment and need high cost to install and keep a maintenance of the system. The lifter of freight transportation robot is designed to load and unload a baggage through up and down motion. Also, ultrasonic sensor, RFID, QR-code and camera sensor is used to carry out various functions while the robot navigates in the various environment. We design an operation method of the mobile robot in order to effectively arrive a goal position and transport a freight. The proposed methods are verified through various experiments.

Recently, the research and development of weapon systems have expanded from ILS centered on acquisition costs to LCS, including operating maintenance costs. Regulations define the provision and formula of operating maintenance costs, but this does not consider the characteristics of the design and operation/maintenance of real weapon systems based on engineering calculations. Therefore, this study suggests a simulation design method to complement these areas and produce more accurate operating maintenance costs. The research procedures are as follows. First, the provision and formula of operating maintenance costs were defined to make the simulation results applicable. Second, a simulation model was developed by reviewing design considerations so that the simulation results reflect reality more accurately. The design considerations include the PBS of weapon systems, operation schedules, specifications for operation/maintenance/warehouse facilities, and basic cost information (personnel expense and spare part/equipment cost). This study is expected to be effective in calculating the operating maintenance costs more easily and accurately.
