The functions of stocking and releasing in logistics center consist of three major procedure such as receiving, shipping and stock managements. Each process includes various sub-processes which are complicatedly connected with each other. Furthermore, lots of operators execute various tasks in the different sub-processes, simultaneously. It makes difficult to standardize, monitor, and analyze the processes. This paper proposed the quantitative methodology using process mining approach to discover and analyze receiving and shipping processes. For this purpose, the PDA operation log data is analyzed to build a realistic process model. The deduced model has been compared with official process model. In addition, task assignment and social networks analysises are carried out by utilizing process mining tools. Also, it has been proposed how to improve the processes with the analytical simulation model based on the results of process mining.

Purpose - As the global product network expands through both internationalization and diversification of the multimodal transportation system, corporate strategies have shifted to emphasize the importance of a high value-added international logistics system. To guide policies and strategies to attract relevant industries, this study aims to analyze the location competitiveness of regional logistics distribution center to serve Northeast Asia. Design/methodology - Multi-criteria techniques are considered to offer a promising framework for evaluating decision-making factors. This paper employed an analytic hierarchy process to analyze the hierarchal structure of determinants for selecting the location of a regional logistics distribution center. Adopting both qualitative and quantitative evaluations, this study suggest political implications for a regional logistics distribution center development, such as the direction of political support, service differentiation and infrastructure development. Findings - This study developed a location competitiveness evaluation model, based on the case study of the major port-cities in Northeast Asia. Evaluation model incorporates five factors underpinning 17 components extracted using factor analysis. The results revealed that the logistics factor is the most significant factor for evaluating the competitiveness of a regional logistics distribution center. The remaining factors were market, costs, and services environment. Comparing qualitative and quantitative evaluations, results provide useful insights for a regional logistics distribution center development in Northeast Asia. Originality/value - This study revealed differences between qualitative and quantitative evaluations. The finding implies that prior works on evaluation models of competitiveness has not successfully measured the gap between quantitative data and expert' evaluations. To overcome this limitation, this paper considered both actual data such as actual distance, cost, the number of companies located, and expert opinions.

The purpose of this study is to let the entire logistics system be managed in cyberspace by effectively sharing the logistics information between companies involved in the process, changing conventional commerce to electronic commerce. Most of the goods traded through electronic commerce are small goods involving small business transactions. This produces many problems in shipping and delivery and the leads an inefficient logistics system. Another problems is that there is no sharing of information that process the logistics flow and no systematic management of pick-up and delivery information. As a result, rise in logistics cost, longer delivery period and poor service quality are inevitable and these results are becoming an obstacle in the widespread usage of the electronic commerce. Companies that are part of logistics center can cooperate logistics business in Cyber space and share the entire logistics information through the cyber logistics center. This turns out in effective sharing of logistics information, and thus, allows efficient management of logistics, improves logistics service, and reduces logistics cost.

In this paper, we design Real-Time Postal Logistics Operational Model and System as a to-be system. Current postal logistics information system, named PostNet, is a basic infra system designed for an end-to-end IT-driven process, from mail acceptance to delivery, linked with internal and external systems. Recent competing circumstances drive demand for more intelligent information system. So we design real-time postal logistics operational system focused on site operations. we analyze postal logistics operation and interview field workers and establish real-time postal logistics operational model to solve operational issues. Finally we suggest system specifications.

Logistics parks make profits using the efficiency of time and space. Such logistics parks play an important role in a corporation creating operating profits as well as acting as a method of alternative investment for individuals. Logistics parks no longer simply store materials, but have become a place that plays an important role in various areas of corporate and individual activities, and thus the analysis of the selection of the location of logistics parks and the related characteristics is extremely important. The estimation model is established by the weights for industry derived from AHP(Analytic Hierarchy Process).

The importance of environmental protection has been increased recently. Thus the environmental management was settled in an important global competition factor. In the meantime logistics cost occupied the 8.03% of sales at 2011. This portion was greater than the portion of other countries and it was needed the reduction of logistics cost to secure the competition power. As thus in this paper we prepared the process which diminish the environmental discharge and decrease the logistics cost. We proposed the process to apply the MFCA to SCM, until now the MFCA had been used generally in manufacturing process. We defined the loss in SCM and the plus logistic, minus logistic, logistic center and the classification of cost to adopt the MFCA to SCM.

The economy is advancing at quite a bit is the role of the Distribution Center, a rise is evolving and mullyuryang Any existing storage facilities were not creating added value from contact with the customer service centers play the role. In order to increase its market competitiveness also pl approach to three in order to enforce cost savings and run. But by industry, the goods, operating characteristics of the cooperating in order to differentiate themselves with the operating process of improvement of operating system, including costs and took lots of time of service.Quality is lower ; all were missing. Such logistics centers, standard management model to address a little bit problem with highest academic. I want to try send it to, each product-category's industrial and business forms, standardisation is really a difficult situation, current study is further progress all you if you are The process managed to turn component is sure that we will be able to be judged.

수출기업의 경우 최종 바이어에게 물품을 인도할 때까지 다양한 불확실성을 회피하고 안정적인 물품인도를 위한 수단으로 해외 물류센터를 이용하고 있으며, 물류센터에서 제공되는 품질 수준에 따라 바이어와의 지속적인 거래관계 구축을 도모할 수 있다. 이에 본 연구에서는 수출화주 기업을 중심으로 이들 기업이 갖고 있는 기업특성에 따라 해외물류센터를 활용하는 동기와 현지에서 이용하는 물류센터의 서비스 품질 지각에 차이가 존재하는지 분석하고자 했다. 분석결과, 해외물류센터의 활용 동기에 있어서는 기업의 규모와 제품특성에 따라서는 물류센터를 활용하는 동기에 인식차이가 존재하지 않았으며, 다수의 응답기업에서 국내외 경쟁사에 대한 대응, 바이어의 요구를 충족하기 위해 해외 물류센터를 활용하는 것으로 나타났으며, 해외물류센터 활용 시 지각하는 서비스 품질에 있어서는 물류센터 내 포장 및 라벨링 작업에서 지각하는 품질 수준이 낮은 것으로 나타났다. 또한 주로 문제발생 대응, 정시배송, 주문진행 정보 서비스 등의 변수에서 물류서비스 품질을 높게 지각하고 있는 것으로 분석되어졌다. 특히 취급제품의 특성에 따른 품질 지각 수준이 다른 것으로 분석되어 향후 바이어가 수입하는 제품의 특성에 따라 적절하게 물류센터의 서비스를 활용해야 할 필요가 있는 것으로 분석되었다.
