Many manufacturers applying third party logistics (3PLs) have some challenges to increase their logistics efficiency. This study introduces an effort to estimate the weight of the delivery trucks provided by 3PL providers, which allows the manufacturer to package and load products in trailers in advance to reduce delivery time. The accuracy of the weigh estimation is more important due to the total weight regulation. This study uses not only the data from the company but also many general prediction variables such as weather, oil prices and population of destinations. In addition, operational statistics variables are developed to indicate the availabilities of the trucks in a specific weight category for each 3PL provider. The prediction model using XGBoost regressor and permutation feature importance method provides highly acceptable performance with MAPE of 2.785% and shows the effectiveness of the developed operational statistics variables.

According to result of this paper, shipping companies tend to choose a third party logistics company that is able to provide consulting services that is the core of the administration of distribution. Shipping companies expect that the consulting services would be able to increase the efficiency through utilizing not logistics functions of shipping, unloading, storage, and information but performance indices of logistics activities. Because shipping companies generally regard that third party logistics not only has no expertise but also is small, in order to activate third-party logistics industry, the consulting services should be improved.

Nowadays, the tendency of world air cargo is noteworthy and air traffic in terms of cargo throughput will no doubt grow significantly in the new Region, with India and China's booming economy and the upcoming Olympics 2008. For example, in the first 11 months of 2006 cargo traffic was increased by 6.3%. First of all, the market of air cargo in Korea grows very quickly and diversifies. It is an essential factor in the process of development of Northeast-Asia as a hub for Air Cargo logistics. However the process of air cargo in Korea is complex as compared with other north-east asia nations. At the same time, it has many problems and causes inconvenience to owners of freight. This paper investigated the process of air cargo in Korea now and analyzed problems of the process. We emphasize that 4PL is the excellent solution from among many alternatives. It is also worthy of notice that EPCglobal network strengthen the role of 4PL. In conclusion, the 4PL system based on EPCglobal network will result in a good success, so it will raise a prestige of air cargo in Korea to a higher position.

21세기 들어와서 물류기업간의 경쟁이 날로 격화되고 있다. 이에 따라 물류비 절감, 고객 서비스의 향상, 정보통신기술의 활용 등 여러 요인에서 상대적인 경쟁우위를 확보하기 위한 노력을 경주하고 있다. 중국은 WTO 가입 후 물류산업분야에도 많은 발전이 있었지만, 아직도 다른 나라에 비해 GDP 대비 물류비의 비중이 높아 중국 경제에 부담으로 작용하고 있는 실정이다. 제4자 물류기업은 한정된 경영자원을 핵심역량에 투입하고 비 핵심활동인 물류활동은 전문물류업체에 아웃소싱을 하게 되었으며 물류 아웃소싱이 확대되면서 물류의 중요성이 대두되게 되었고 그에 따라 물류의 수요 또한 증대되게 되었다. 따라서 중국에서 제4자 물류는 많은 장점에도 불구하고 정부와 기업들의 문제로 본질적인 한계점을 가지고 있다. 본 논문의 연구 목적은 중국 제4자 물류에 대해 중국정부와 중국물류산업의 문제점을 제시하고 중국에서 제4자 물류를 도입하기 위한 기업 및 중국정부 차원의 해결방안을 제시함으로써 중국에서 제4자 물류의 발전에 기여하고 한국 제4자 물류기업의 중국진출을 촉진시키는 것이다.

Purpose - According to the actual change of the logistics concept, the outsourcing activities of companies are actively progressing, and this is proceeding to third-party logistics and fourth-party logistics. This change in logistics situation raises the need for an in-depth understanding of four-party logistics. Research design, data, and methodology - In this study, first of all, the theoretical aspects of changes in the logistics concept are identified, along with the outsourcing and third-party logistics. Finally, the concept of four-party logistics, the background of its introduction, and future prospects will be explored. Result - The meaning of physical distribution is now passing through the existing three-party logistics and entering the era of four-way logistics. In addition, cost reduction and improvement of customer service through advanced logistics strategy can be said to be the company's competitiveness. Through this study, it can be seen that the conceptual change of logistics and the introduction of four-party logistics are closely related to the survival of the company's deficit in the market. Conclusion - In modern society, logistical competitiveness is the competitiveness of a company, and logistical activities of a company can be achieved through the process of entering the four-party logistics from the existing third-party logistics based on outsourcing. Then more customer-oriented service can be provided.

We must adapt to the rapid speed of information-oriented society well for outstanding central logistics nation of 21th century's Northeast Asian. Moreover, we must provide customers or enterprises with sufficiently satisfactory service about diversified desire of customers. In particular, we try to find the service process with RFID about air logistics that has many demands and is required to develop accurate and rapid service technique. As a result, we apply RFID to overall process of air logistics. After that, we will test the process and analyze results of the test. We are going to provide real possibilities of RFID enterprise and other service process. We will promote technology development of service process for air logistics' service.

최근 B2B 전자상거래 확산에 따른 물류문제를 해결하고 오프라인 물류와의 차별화롤 시도하기 위한 목적으로 다양한 물류측면의 대안이 제시되고 있다. 먼저 물류산업 자체의 e-business화를 추진함으로 기존 물류체계에서의 고비용 문제, 책임 소재가 불분명한 서비스 문제를 해결하고 운송정보의 실시간 제공을 통한 발주자, 화주자 간의 긴밀한 커뮤니케이션 형성과 해외시장을 겨냥한 글로벌 물류체계를 구축해야 한다. 다음으로 물류업종의 지나친 세분화, 기존 물류업체의 영세성과 혁신마인드의 부족, 그에 따른 제조 유통업체의 경쟁적 자가물류 확충의 악순환으로 제3자 물류시장 성장기반이 제한되어 오는 등 구조적인 문제점을 극복하기 위하여 주요 운송업체가 영세한 화주나 창고관리 위탁업무까지 대행하여 주는 지금까지의 제3자 물류 체제에서 대기업이 물류시장에 새롭게 진출하면서 사이버 물류시스템을 기반으로 기존 주요 운송업계와 VAN 사업자가 장악하고 있는 물류정보 서비스를 주도하는 제4자 물류체제로의 전환이 요구된다. 왜냐하면, SCM과 전자상거래 환경 하에서는 공급 망 내의 물류를 최적화하여 기업의 경쟁력을 강화하기 위해서 기능적 아웃소싱의 단계를 거쳐 물류기능의 통합과 운영의 자율권이 증대, 전체적인 공급연쇄 솔루션을 제공하는 서비스 제공자와 함께 기업의 경영자원, 능력, 기술을 관리하고 결합하는 공급연쇄 통합자로서 제4자 물류가 필요하기 때문이다. 이와 같은 제4자 물류체제가 본격 형성될 경우 물류정보와 인프라가 복잡하게 업혀있는 기존 물류산업이 재편되고, 특화된 물류솔루션을 바탕으로 한 산업별 물류체제 구축이 가속화될 것으로 예견되며, 일반기업 입장에서 물류부문의 아웃소싱이 촉진되어 물류산업기반이 확충될 수 있을 것이다.

These days, international air-logistics demand is getting bigger and bigger by increasing in trading volumes of export and import of Asia. It makes the air logistics of stakeholder to invest in air logistics facilities and information systems for meeting the growth of air transportation. However there are some problems that the efficiency of investment is not good by duplicately investing in information systems and moreover not compatible with each other because the stakeholder is investing in individual information system and air logistics facilities instead of constructing the integrated infrastructure. In this paper, we investigated the export, import, and transshipment process of air logistics to simplify air logistics process through the RFID(Radio Frequency Identification) application and the 4PL system.

Prior to the service evaluation, many kinds of its attributes must be identified on the basis of rational decision owing to complexity and ambiguity inherent in logistics service. there are so many evaluation methods but they are not applicable to logistics service the have property of non-additivity and overlapped attributes. Therefore, probability measure can not used to evaluate logistics service but Fuzzy Measure is required. And the method should be easy to calculate it Recently Fuzzy theory has been applied in Various evaluation problem. Fuzzy evaluation based on Fuzzy theory can accommodate fuzziness in judgement with people through introducing Fuzzy Measure. In this paper, Hierarchical Fuzzy Process is applied to evaluate level of logistics service in Korail and the biggest six logistics companies in the korea which is called 3PL Company. Also Fuzzy Relation Equation which is problem identifying evaluation value at these fuzzy evaluation is applied to verify relation between Input and Output data through @-operation. Therefore, we apply this Fuzzy Relation Equation to Hierarchical Fuzzy Process and verify evaluation value which objects of evaluation are able to possess.
