The mobile communication technology would be one of the most appropriate means for achieving process innovation in the actual business area. This article performs a simulation study to examine the effect of introducing a mobile technology to the after-sales service and its logistics process. The performances of the two different systems, before and after introducing a mobile technology, are examined based on operational cost, operational efficiency, and customer service level using a discrete event simulation. The real-world data, extracted from a leading Korean electronics firm, was collected for this study. The results show that the TO-BE(after) model outperforms the AS-IS(before) model over all the performance indices. And the effects of introducing the mobile technology are more significant on the more tightly controlled inventory policy.

The third party logistics(3PL) is given a definition as logistics activaties providing a comprehensive logistics services, all or partly outsourced by the customer on longer term contract basis, ranging from making logistics strategies to implementing information technology services. The growth of the Third Party Logistics (TPL) business has caused many firms from different industries to enter the field. In this study, it is presented to describe a defintion and development precess of the third party logistics and shown to present strategic issues comparing to third party in foreign and domestic area. and apply some issues of importance when managing the continued TPL business strategy in domestic area.

Recently, due to emerging technologies such as radio frequency identification(RFID), global positioning system(GPS), and wireless mobile communication technologies, it is possible to build up the infrastructure for tracking and tracing product logistics data at any place and at any time. However, for implementing the infrastructure, it is necessary to develop a suitable management method for product logistics data. To this end, this study deals with a resource description framework(RDF) based modeling and application method for product logistics data in the ubiquitous environment. It will give us the capability to control product logistics data, which leads to streamline logistics operations.

대다수 산업과 무역유통 기업은 물류 자원을 통합한다. 기업들은 제품 운송부분을 원가를 절약하기 위해서 전문적인 물류회사에 맡긴다. 여기서 전문적인 물류회사를 제 3자 물류라 한다. 컴퓨터와 인터넷의 발전에 따라 발주와 화주 그리고 제 3자 물류회사 간에 인터넷을 통해 연결된다. 여러 회사에서 사용하는 관리 프로그램이 각각 다르기 때문에 이질적인 데이터는 제 3자 물류정보시스템에 큰 문제가 되었다. 본 논문에서는 지식 공학 방법론을 이용하고, prot$\'{e}$g$\'{e}$를 개발도구로 이용하여 도메인 온톨로지를 구축하였다. 그리고 물류 온톨로지에 규칙 베이스를 만들어서 그들이 완전하게 개념간의 관계를 표현할 수 있다. 또한 물류 온톨로지와 룰 베이스의 기초에 제 3자 물류회사의 배송센터에 지능 정보시스템을 설계하고 정보 시스템의 작업 프로세스를 시각적으로 보여주도록 실례를 제시하였다.

치열한 항만간의 경쟁에서 우위를 확보하고 항만의 주요고객인 화주와 선사들의 요구사항을 만족시키기 위해서는 물류서비스를 개선해야한다. 하지만 물류서비스 불만의 대부분은 터미널 내부의 문제이기 보다는 화주의 잦은 운송변경 및 선사로부터 제공되는 하역정보나 운송사로부터 반입되는 화물정보의 부정확성에 기인하고 있다. 따라서 본 연구에서는 이러한 문제들을 해결하기 위해 장치장의 업무흐름을 프로세스 중심으로 재설계하고 장치장관리 프로토타입 시스템을 구현하였다. 또한 장치 할당 계획 수립에 선복예약목록 정보가 불충분한 화물정보를 보완하여 장치장 관리에서 협업적 공급망을 구성하는데 이용될 수 있음을 확인 하였다.

Visibility of the flow of goods is an important service element when considering how to improve the quality of a logistics service. Registered mail service of Korea Post, one of logistics service providers, currently supply information on the handling of postal items, such as receipts and delivery and arrival times to customers. However, internally problems related to excessive spending on operating expenses and less reliable tracking and tracing information exist due to errors in the information acquisition and link handling processes, leading to unnecessarily duplicated tasks. Therefore, the purpose of this paper is to propose process optimization method for improving the quality of tracking and tracing information for registered mail items. We analyzed the process and information control system of the current registered mail service and identified the basic causes of the existence of less reliable tracking and tracing information. And we present optimized mail handling and information management process for removing internal problems. Test results using tracking and tracing information examples show a significant performance of the proposed method.

Owing to the latest changes in the IT environment and the advancement of RFID (Radio Frequency Identification) technology, the RFID technology has been frequently applied to the field of logistics and distribution. Now it is possible to acquire information in real-time more accurately and promptly as compared to data collection in the past, through the application of the RFID technology. However, in terms of the application of the RFID technology, the range of the field of logistics and distribution is considerably widely distributed. The management system that is able to monitor the RFID system installed in logistics centers and stores distributed in environmentally many regions, in real-time in the center is insufficient. Therefore, this study proposes a management system which is capable of transmitting the report of the occurrence of errors according to the pre-defined error types at the time of the occurrence of errors in the RFID system installed at each strategic foothold, in real-time to SMS and to the integrated monitoring system, and of taking actions for those errors from a remote place by using a mobile device. The purpose of the error management system proposed in this study is to minimize a data loss in the supplying network by quickly coping with errors in the area where the RFID system is installed.

Logistics companies distinguish between medium-sized business and small business according to the size of enterprises. Of course, conglomerates are called global corporations. In this study, mid-sized companies over a certain size or more and those below are classified and decide the priorities among important factors to secure competitiveness in logistics companies are determined through AHP technique. Mid-sized companies are companies that can provide more than two logistics services. For example, they provide warehousing and transportation services in the same time. small companies are companies that can mostly provide one functional service. Warehousing, transportation, manpower, and information are listed as factors in this study. As a result of the study, medium-sized companies emphasized on the importance of transportation. When it comes to small companies, warehousing was emphasized as an important factor. Due to the simultaneous and contemporary service of warehousing and transportation in small-sized company, the reliable image of the company will be underestimated in case of delays in transportation. Competitiveness will also be weakened. Global corporations or conglomerates will start to consider relocating warehousing areas to others except for the central storage hub. They won't plan to invest directly, either. Therefore, it will be possible to secure competitiveness by providing the function of warehousing and to signed easily partnership.

중국 길림성은 농산물이 풍부하며, 농산물을 이용한 부제품이 많이 생산되고 있다. 농산물의 유통은 원활한 콜드체인 물류의 지원이 필수적이지만 중국 길림성의 콜드체인 물류는 비교적 낙후되어 농산물의 낭비되는 원인이 되고 있으며 농가소득 향상에 도움이 되지 못하고 있다. 본 연구는 중국 길림성의 신선 농산물의 콜드체인 물류 발전에 영향을 미치는 요인을 도출하고, 계층구조분석기법(AHP)을 이용하여 도출된 요인들이 농산물 콜드체인에 미치는 영향에 대하여 분석하였다. 계층구조분석기법(AHP)을 이용하여 제약요인의 가중치를 분석한 결과 농산물 콜드체인 물류 원가, 정보기술응용 및 시장기반 콜드체인 물류가 길림성 농산물 콜드체인 물류 발전에 영향을 미치는 3대 주요 요인으로 나타났다. 본 연구는 중국 길림성 농산물 콜드 체인 물류 발전방향을 제시하는데 의의가 있다.
