This study conducted a case study and a questionnaire analysis in parallel. In the case study, a study was conducted on domestic manufacturer A by analyzing pallet loading efficiency of RRP(Retail Ready Packaging) products and pallet loading efficiency of MWC(Membership Wholesale Club) delivered products. As a result of the pallet loading efficiency simulation of 50 RRP products of Manufacturer A, it was 80.0% based on the T-11 type pallet and 84.3% based on the T-12 type pallet. It was found It refers that the route of producing the product from the manufacturer A and delivering it to the MWC A in the form of RRP resulted in the decrease of the pallet loading efficiency through the change of the loading pattern and the adjustment of the number of loads. As a result of analyzing the questionnaire about whether the overall efficiency of the supply chain will be improved if the operation of the packaging system considering the SCM(Supply Chain Management) aspect is χ² = 178.500, there was a statistically significant difference at the significance level of 0.000. Manufacturers and logistics companies answered "yes" the most, but distributors answered "is average" the most, confirming that the packaging can be constructed with the highest operational efficiency. Therefore, as a result of confirming the impact of packaging design considering the SCM aspect on logistics efficiency, it indicates the importance of closer collaboration between manufacturers and distributors.

Spain is Europe's second-largest country with total throughput reaching 16.7 million twenty-foot equivalent units (TEU) by 2020. The purpose of this study was to measure and compare the efficiency of 17 container terminals. As a study method, the DEA-CCR model, undesirable variable, and Malmquist Index (MI) were used for data envelopment analysis (DEA). The study results are as follow: (1) DEA-CCR is used to evaluate basic efficiency. The most efficient terminals are decision-making units DMU 1 (APM Terminals (Algeciras Port)), DMU 2 (Total Terminal International Algeciras (Algeciras Port)) and DMU 5 (Barcelona Europe South Terminal (Barcelona Port)). (2) Undesirable DEA was conducted to suggest inefficiency from the undesirable output. Overall, the efficiency scores were reduced. However, DMU 1, DMU 2, and DMU 5 maintained efficiency scores regardless of the finish factor. (3) Malmquist Index was used to observe technology and efficiency changes dynamically. The changes in TCI affected Spanish container terminals more than the Technical Efficiency Change Index (TECI) in 2018-2019. However, in 2019-2020, the TECI was 2.706, higher than the TCI value, indicating that the change in TECI had more influence on the increase in productivity. This study offers a broader understanding of Spanish container terminals.

글로벌네트워크 확충을 통한 물류창고 중심화 정책으로 물류창고는 합리적 위치, 합리적 시기, 탄력적 대응으로 운영하므로 부가가치를 높이고 효율성 제고를 통한 경쟁력 강화방안이 요구된다. 보관물류 서비스를 제공하는 물류창고업 자체의 생산성을 위한 연구는 아직 미흡하다. 본 연구는 글로벌 물류기업 40개 이상의 기업에서 상위 35개 물류기업을 선정한 후 2007-2010년까지 글로벌 기업의 물류창고의 운영의 성과분석을 위하여 동태분석을 하였다. 본 연구는 결과는 DEA Window모형에서 VersaCold Logistics Services가 가장 안정적이며 Fed Ex Supply Chain Services/FedEx Trade Networks가 가장 불안정적인 것으로 나타났다. 2009-2010년 기간은 상위 물류기업보다 하위 물류기업의 생산성이 증가하는 특징을 보이고 있다. 그리고 2007-2008년 기간에는 생산성 감소가 있는 것으로 나타났다. 글로벌물류기업별로는 DHL Supply Chain & Global Forwarding와 Maersk Logistics/Damco의 경우 3기간 평균 생산성이 증가하였으나, SCI Group Inc.와 Schneider Logistics, Inc.의 경우 평균 생산성이 감소하였다. 그리고 순수기술효율성의 변화인 Catch-up 분석과 기술진보를 나타내는 Frontier 효과분석을 하였다. 본 연구의 창고운영 면적에 따른 분석을 하지 못한 한계점이 있다.

Franchise store retailing is taking on ever greater roles in business and commerce in China. The diverse product range, small-batch order, high frequency and time-specific requirements inherent in retail logistics make it the most complicated of all categories of logistics. In franchise store retailing, expanding business scales make trans-regional development a trend. Without a well-functioning logistic system, the standardized delivery of products would be held back, impacting trans-regional development strategy and operational costs. Therefore, the efficiency of franchise store retailing largely depends on logistical efficiency. The integrated and streamlined management of franchise stores depends in large measure on their logistical centers. As such, logistical centers constitute the key link and bears on core competitiveness in franchise store retailing. This thesis begins with an analysis of the current developments and four basic logistical models of franchise store retailing in China, proceeds to summarize developmental trends as well as focal issues and proposes an efficiency enhancing plan.

Purpose: The study attempts to explore the operational performance of the existing Malaysian logistics companies and the extent of their adoption of digitalization. The role of digitalization in enhancing the performance of companies in the logistics industry in Malaysia, for value creation, is the topic of study. Research design, data and methodology: A qualitative research method with a semi-structured interview approach was applied and judgmental sampling was used as the sampling technique to collect data. The research has chosen nine companies in the logistics industry in Peninsular Malaysia, with the interviews aimed at eleven members of top and middle-level management. Data analysis was performed using logical system techniques to examine and evaluate data, reorganizing feedback, comparing it with literature, and transforming it into structured, valuable information after interviews. Results: The study revealed mixed opinions on digitalization in logistics, despite its potential benefits such as improved operational efficiency, real-time information, and customer service. However, high costs may hinder financial performance and require revisions due to stakeholder involvement. Conclusions: The Malaysian logistics industry's adoption of digitalization is gaining traction, with most companies satisfied with their status. However, challenges like cost and inefficiency persist, prompting calls for government support to improve efficiency and reduce costs while ensuring sustainable transportation.

본 연구는 항만 물류배후단지에 입주하여 운영하는 입주업체들의 효율성을 분석하는 것을 연구의 목적으로 하였다. 인천항과 부산신항 항만 물류배후단지 13개 입주기업을 효율성 분석대상으로 하였으며, 투입변수는 투자액, 면적, 종업원 수를 사용하였고, 산출변수는 물동량과 매출액을 선정하였다. 효율성 분석방법으로는 전통적인 CCR 모형과 BCC 모형을 적용하고 이들의 한계점을 극복하기 위해 초효율성 모형과 Super-SBM 모형을 적용하였다. 초효율성 모형의 분석결과, 평균값은 0.777, 표준편차는 0.541로 나타나 각 기업 간 효율성 점수 차이는 33% 정도 존재하는 것으로 분석되었다. Super-SBM 모형의 분석결과, 평균값은 0.649, 표준편차는 0.489로 초효율성 모형에서 여분을 고려할 경우 기업 간 효율성 점수 평균이 약 13% 정도 감소한 것으로 나타났다. 이러한 감소의 의미는 비방사형 여분이 존재하는 DMU의 효율성 점수하락이 평균 13% 정도 됨을 의미한다. 투입요소의 비효율성 분석결과 면적 -33%, 투자액 -33%에 비해 종업원 수의 비효율성이 -45%로 가장 큰 것으로 분석되었다.

The integration of nanoparticles into various industries has spurred interest in understanding their impact on logistics and transportation systems. In this study, we investigate the effect of nanoparticles on the economic aspects of railway logistics transport using a mathematical model. By incorporating factors such as transportation costs, time efficiency, and environmental considerations, we aim to assess the overall economic feasibility of integrating nanoparticles into railway logistics operations. Through mathematical modeling and analysis, we explore how the introduction of nanoparticles affects cost-benefit analyses, resource allocation, and decision-making processes within railway logistics. Our findings provide valuable insights into the economic implications of nanoparticle integration in railway transport, offering potential strategies for optimizing logistics operations and enhancing overall efficiency and sustainability.

세계화를 통해 글로벌 공급사슬은 더욱 복잡해지고, 고객들은 모든 물류서비스를 통합적으로 제공받을 수 있는 기업에 대한 의존도가 높아짐에 따라 고객들은 물류 기업에 대해서 가격뿐만 아니라 운영적인 측면에서 높은 효율성을 요구하고 있다. 이에 본 연구에서는 자료포락분석(Data Envelopment Analysis)을 중심으로 전세계 물류산업의 효율성의 추이와 비효율성에 영향을 미치는 요소들에 대한 연구를 진행하였다. 그 결과를 요약하면, 5개년간 세계의 물류산업의 효율성은 높아지는 추세를 보이고 있었으며, 비효율성은 규모에 의한 비효율성보다는 순수기술효율성에 의해 나타난 비효율성에 의해서 나타나고 있었다. 비효율성에 영향을 미치는 외부적인 요소를 살펴보면, 우선 세계화는 비효율성에 영향을 주고 있다. 세계화의 요소 중에서는 경제적인 요소보다는 전반적인 세계화 정도가 더 영향을 미쳤으며, 인프라와 관련되어서는 인력, 금융적 지원, 기반 등 소프트웨어적 측면의 영향력이 더 유의했으며 법제도적인 측면에서는 집행의 투명성, 법제도의 효과가 유의하게 영향을 미치는 것을 밝혀냈다.
