I think that there are few domestic enterprises that recognize standardization of logistics equipments is necessary, which causes a lot of waste in costs and also reduces their business competitiveness. The purpose of this paper is to make the companies be aware of this situation, to exactly analyze where the Korean logistics equipments status are, and further to provide practical directions of methods and activities for effective standardization. Through analysis in the study, there were some findings, as listed below. First, the standardization level of each company varies depending on its own corporate characteristics. Second, if a company adopted standardization process in logistics equipments, it would accelerate process of work efficiency or productivity. Third, when logistics equipment are standardized, it would boost efficiency in storage utilization. Fourth, the delivery services through this standardized logistics would be implemented at a higher speed than before due to the accelerated flow of materials. According to the above findings, it is confirmed that logistics standardization would greatly affect on business performance positively. For the domestic manufactures to facilitate logistics system more easily, as an easiest way, it is required to build logistics standardization teams and surveys. Then afterwards, to achieve it earlier than expected, the company-wide education and training for workers have to be followed to let them be aware of necessity and inevitability about standardized logistics.

The efficiency of port operations is an important indicator of port development. Moreover, there is excess handling capacity in Chinese ports, which results in a slower speed of development. Under the detrimental environment of the international shipping market, it is necessary to improve the operation efficiency of ports for long-term development. This paper provides an assessment of the competitiveness of Chinese seaport companies using the Boston Consulting Group's matrix, and efficiency measurements using a data envelopment analysis and the Malmquist method. This analysis showed that highly efficient companies reformed their development strategies, which should be a solution considered by less efficient companies, such as Shenzhen Yan Tian Port Holdings Co., Ltd.. Although, having high throughput should be reformed in the investment structure. This research will assist port companies in gaining effective operating experience, and governments in establishing strategic planning to enhance the efficiency of port development.

Purpose - This is a case study aimed at finding a solution for improving the pallet loading efficiency in the process of delivering products through a transshipment using the T-11 and T-12 pallet systems. The study proposes a solution by demonstrating the case of a certain manufacturer A, who aims to reduce the logistics cost by using packaging sizes that are commonly applicable and can improve the compatibility between the T-11 pallet system, designated as the standard pallet in Korea, and the T-12 pallet system, which is commonly used in other foreign countries. The use of common sizes increases compatibility among the two systems and reduces both logistics and environmental costs. Thus, this case study calculates the quantitative benefits of applying common packaging sizes to improve the compatibility between the T-11 and T-12 pallet systems. These systems are considered to be the most important and widely used transportation systems in the global logistics industry. Research design, data, and methodology - This study examined manufacturer A's representative product and delivery system and assessed how manufacturer A was affected by the use of incompatible packaging sizes in the T-11 (1100 mm×1100 mm) and T-12 (1200mm×1000 mm) pallet systems, which were specified in the KS T 1002 standard. In addition, this study analyzed the impact of these packaging sizes on A's logistics cost. The TOPS program (Total Packaging System) was used to simulate pallet loading efficiency,and the main parameter studied was volume, as calculated from length, width, and height. Results - When the sizes of secondary packaging were not compatible across the T-11 and T-12 pallet systems, a reduction in loading efficiency was observed, leading to an increase in logistics cost during transshipment. Such low loading efficiencies led to a further loss of efficiency in transportation, storage and unloading. This may have a possible environmental impact with high social expenses, such as increased CO₂ emissions. Hence, this study proposed that the KS T 1002 standard be amended to include 21 packaging sizes, including 7 sizes of the 600 mm×500 mm category, which are compatible with both the T-11 and T-12 pallet systems. Conclusions - This study found that the 69 standard sizes under the T-11 pallet system and the 40 standard sizes under the T-12 system in the KS T 1002 standard can be simplified and reduced to 21 mutually compatible packaging sizes, enabling logistics standardization and reducing national-level logistics costs. If the government pays attention to this study and considers the standardization of common sizes for the T-11 and T-12 pallet systems and amends the KS T 1002 standard, this study will deliver practical value to the global logistics industry, apart from being of academic significance.

In general, companies operate systematically in response to financial risks such as exchange rates and liquidity, while they are vulnerable to risks in the manufacturing and sales processes. In particular, logistics refers to the activities for planning, managing and implementing efficient flows from the starting point of goods and products to the point of consumption, The purpose of this study was to develop key risks and key risk management indicators (KRIs) for risks that undermine logistics efficiency so that logistics risks can be effectively prevented and managed. As a result, 40 risk management indicators (KRIs) were developed in a total of six categories in the logistics sector, and the definition, calculation method and early warning grade of each KRI were presented so that companies could prevent risks in advance in logistics activities and contribute to enhancing efficiency of their work.

There are lack of labour and increase in logistics costs due to rapid change in logistics environments and the demand for logistics. The reality is that over spending on logistics costs are getting worse due to lack of logistics standardization. An example will be excessive logistics costs caused by unsatisfactory use of logistics equipments in wholesale markets. The logistics efficiency is falling due to delays in using logistics equipments and standardization. Therefore, there needs standardization of logistics functions and unit of handling in each stage from packing, unloading, storage, transporting, logistics information and needs logistics standardization on equipments, machineries used for the above. Standard unified with standardization is called specification and if standardization is applied broadly in manufacturing or processing, inspection than each process in terms of production can be managed rationally and labour skills will improve and product quality will be evenly maintained and compatability of each part in terms of assembly will be maintained thus materials and labour could be saved thus results in increasing productivity and lowering production costs. Also, if it is applied in industry at state-level then there will be rationalization in consumption in circulation as in purchase of raw materials, sales of products, purchase of products by consumers and contribute in improving compatibility and fair transactions. This paper is aimed to help in first solving factors affecting the most in improving logistic efficiency among unit load system and logistic hollowization, standardizing logistics base, standardizing logistics information. The study conducted surveys on limited companies but hope that in the future the target companies can be divided further into types, industries and conduct more demonstrative analysis.

최근 많은 물류 기업이 프로젝트 물류 관심을 가지고 있음에도 불구하고 기존 연구는 단순히 프로젝트 물류시장의 성장성과 프로젝트 물류의 높은 장벽과 중요성만을 언급하는 연구한계를 가지고 있다. 이러한 측면에서 본 연구는 DEA분석을 활용하여 국내 주요 해외 건설 EPC기업에 등록되어 해외 플랜트 건설 프로젝트 물류 업무를 수행하고 있는 포워딩 업체의 운영 효율성을 분석하고자 한다. 효율성 분석을 위하여 DEA 분석 기법 중 Super-SBM 분석 및 Malmquist 분석을 활용한다. Super-SBM 분석 결과, DMU 5가 1.807로 1 순위로 나타났다. DMU 5는 모기업인 H사의 안정적인 물량공급과 대형 기업 중 가장 적은 투입과 산출 변수를 가지고 있어 다른 대기업에 비해 효율성이 높게 나타났다. Malmquist 분석결과로는 기술적 발전인 TCI는 변동이 많은 반면 TECI는 비교적 변동이 적은 모습을 확인하였다. 더불어 대기업과 중소간의 규모의 차이가 있어 각 집단에 맞는 효율성 개선 전략을 파악하여 실무에 적용할 필요가 있다.
