It is expected that logistics standardization have an great effect on industry and national economy due to cost saving and improving efficiency. Therefore all countries of the world make a strenuous effort to take a lead of logistics standardization Despite such efforts of every country, our country remained a lukewarm attitude about logistics standardization. Especially, our country remained a lukewarm attitude about logistics standardization effect quantify. We have to suggest the necessity of standardization and the effect for carrying out logistics standard. So, this study performed literature review and case study for development of effect valuation method. Also, this study developed effect valuation standard for quantifiable standardization effect and drew the effect valuation standard model. First, the measure of preliminary effectiveness was chosen for MOE selection. As a results, vehicle load ratio, delivery cost, keeping space efficiency warehouse automation ratio, etc. were selected. Then, vehicle/truck load ratio, warehouse keeping efficiency, up unloading hour, packaging cost, consistency transportation ratio were chosen for MOE of pallet standardization.

The purpose of this paper is to develop a benchmark of performance standards for Global Logistics Provider in the merging logistics market. The Data Envelopment Analysis (DEA) can be employed to compare and analyse the efficiencies of Global Logistics Provider(3PL, 4PL). That is because Global Logistics Providers are able to reach the highest level of efficiency by using Logistics institutions and Logistics service systematically. This research is focused on analyzing the efficiencies of top 40 Global Logistics Providers. The framework assumes that the Providers use three inputs to produce one output. The inputs include number of employees information system, and number of warehouses. The output is the annual turnover. The results show that Panalpina, C.H. Robinson Worldwide, Maersk Logistics/Damco, Hub Group, Lander Global Logistics on Global Logistics Providers are the efficient providers. This paper also allows the inefficient DMUs to establish their benchmarking strategies. The strategies are dependent on the assets such as number of employees, information system, and number of warehouses.

Purpose: The purpose of this study is to develop a sprinkler head that can be controlled and initial suppressed by installing it in a rack-type warehouse. Method: Considering the spray radius and spray pattern, various deflectors were designed, and the spray angle, discharge characteristics and protection performance test was conducted, and these results were compared and analyzed. Results: An optimal sprinkler head was developed to protect full load, front side of a commodity with minimum water volume 115L/min. Conclusion: The developed head of K-115 and 1Bar pressure was tested with one tier storage confirming that the fire control is carried out without burning all the loadings. In addition, the vertical distance from the top of the load to the deflector shall be separated by 450mm and installed to allow sufficient discharge to the outer part of the commodity.

Recently Amore pacific rack-type warehouse fire broke out and argue an urgent improvement of fire protection design code including automatic sprinkler and detection design. Various type of commodities have their unique fire characteristics from fire spread rate and heat lease rate and fire hazard depends on storage height, rack arrangement, aisle width, fire load etc. With increasing ceiling height for more storage space prevent effective water spray of sprinkler head, also delays detection time causes failure of early suppression. To achieve fire protection code performance of this occupancy, Major code articles relating to a classification of commodity, sprinkler system installation, detection and fire fighting are reviewed and suggested based on fire case analysis, code review between country and field survey.

물류의 증가로 생산된 제품이 소비자에게 전달되기 전 저장하는 제품 창고의 운영과 유지는 제품원가의 큰 부분을 차지하게 되었다. 취급작업 횟수의 감소, 신속한 출고 작업, 제품의 효율적 관리를 위해 저장설비의 설치, 저장 공간의 추가 확보 등의 시설 투자 방법으로도 이런 문제를 해결 할 수 있지만 기존 저장 공간을 최대한 활용함으로써 취급작업 수를 줄일 수 있다. 저장시설 내에서의 운영방법에는 여러 가지가 있겠지만 저장 공간의 제약이 있기 때문에 제품을 겹쳐 쌓아야 하고 그 경우 반드시 재취급을 고려해야 한다. 재취급 문제는 창고의 취급 효율을 결정 짓는 가장 중요한 문제이다. 따라서 창고의 운영 효율을 높이기 위해서는 재취급을 최소화할 수 있는 방법을 고려할 필요가 있다. 본 연구에서는 기대 재취급을 최소화하는 혼적결정 문제를 다루고자 한다. 혼적결정을 위한 최적화 모형을 제시하였고 해를 구하기 위한 유전자 알고리즘을 제시하였다.

경기도 김포시의 변화가 예사롭지 않다. 한강신도시가 들어서면서 신흥 주거지로 명성을 높이더니, 이제 경인아라뱃 사업이 본격화됨에 따라 산업계의 시선 역시 집중시키고 있다. 경인아라뱃길 사업이 산업계의 주목을 받는 가장 큰 이유는 김포터미널(김포 고촌읍 전호리 일대)에 조성될 '김포물류단지' 때문이다. '김포물류단지'의 북측에는 마리나를 중심으로 관광, 레저 및 수변상업시설이 배치된다. 또 남측에는 컨테이너 부두와 연계한 장고 집송시설 등 물류시설이 들어선다. 가히 문화와 산업이 어우러진 수도권 서부지역 최대의 물류소통 전진기지가 등장하는 것이다. 이 전진기지의 중심에는 삼성에버랜드가 시공하고 있는 '수도권 통합물류센터' 가 있다. 이 센터는 연면적 $63,571m^2$의 물류창고로, 김포물류단지 내에서는 최대 규모를 자랑한다. 즉 김포물류단지를 대표하는 건축물인 셈이다. 때문에 삼성에버랜드는 큰 책임감과 자긍심을 갖고 시공에 임하고 있다. '철저한 안전관리' 로 김포물류단지의 랜드마크를 선보이겠다는 이곳 현장을 찾아가 봤다.

Recently, not only domestic businesses but also overseas businesses are expanding development and investment in automated warehouses as domestic and foreign logistics environments undergo drastic change. In such an environment, automated warehouse systems are being rapidly changed, and automated warehouse systems equipped with diversified functions are being developed accordingly. But the assessment systems of developed automated warehouse system is at a standstill. In the present article, characteristics of the automated warehouse systems in diversified development and trends of technology were analyzed, based on which evaluation items of functional suitability and reliability were derived by referring to ISO/IEC 25000 as the international quality assessment standard to secure reliability of the automated warehouse system, and an evaluation model was developed through the derived evaluation items. Through the present article, evaluation standards of functional suitability and reliability to enhance quality levels of automated warehouse systems are considered to be secured.

Recently, as warehouses became automated, workers are trying to maximize storage efficiency as well as work efficiency. So, using mobile-rack which has wheels or rails at the bottom and minimizes dead space by removing extra passages between racks is rapidly rising as a notable technology. So, this paper seeks how to manage optimally cryogenic warehouse using mobile-rack. At first, routes of mobile-rack and operation vehicle will be synchronized and storage location will be decided with seasonal demand. After that, it will be simulated considering additional factors.
