It is very important to solve the traffic congestion problem and the environment improvement problem at the same time in center of the city. We studied experimentally on the model building method designed the collaboration system as the optimized solution combined above-stated two problems. In order to clarify this method, we studied the logistics system in the department stores of Sapporo city as the concrete object. As the approach, we grasped the logistics problem of the enterprises in Sapporo area by the questionnaire, found the optimized solution by the simulation and the experimentation and designed the basic collaboration system. We are studying to generalize this method in the above model from now.

At present Japanese retailers make it their motto to put more emphasis on CS (Customer Satisfaction) and to reduce logistics cost. In order to cut down the logistics cost, the Japanese retailers are trying to build up SCM (Supply Chain Management). However, it is important to build up logistics systems at first, and as a next step they should do SCM.

If everyone drive a car considering energy saving, cost reduction and improvement of domestic energy consumption can be achieved.It is also effective for environmental measures and climate change problems. In this study, a lot of data has been collected by the digital recorders which are attached at monitored cars. The data obtained from over one hundred monitored cars for one year has been analyzed. Then, it is found that the fuel efficiency is dependent on some of driving techniques. Namely, smart driving can save fuel consumption. Finally, a control system for automobile driving has been developed. This system is useful to satisfy the feedback loop for saving fuel consumption.

European Commission published new white paper on transport in 2001 that placed stress on sustainability for common transport policy toward 2010 and showed the policy guidelines considerate to environment. The white paper stipulates that freight transport is an important issue and promulgates the policy to shift from road to railways, coastal shipping, inland water ways, and intermodal transport. The principal measures are improving quality in road freight transport, revitalizing railways, linking up modes of transport, and eliminating bottlenecks. Freight transport policy in EU to attach great importance to sustainability is an important case for Japan that is forced to take prompt measures to refer to, and expected to develop in the future.

This paper examines the ways in which Radio Frequency Identification (RFID) technology can potentially increase the efficiency and effectiveness of logistics systems. The use of RFID tags allowed the operators of distribution centers to reduce the time required to monitor the delivery and shipping of products. RFID technology can help reduce inventory levels and cut lead time. The deployment of RFID technology addresses a number of issues, and has the potential to enhance the efficiency and profitability of logistics systems.

Though there have been so far many SCM led by manufacturers, those led by wholesalers have often appeared recently too. However there are few SCM experimental studies on a Japanese wholesale industry. The intension of this study is to analyze SCM in a Japanese wholesale industry. From the results, it is demonstrated whether SCM contributes to performances of each wholesale company.

SCM is widely recognized as the management technique for carrying out the innovation of the company. However, the information sharing between two companies does not spread because the business partnership is immature.
Information, especially including a business strategy and goal, data, business process, and knowledge, brings a company a success of SCM. Such information sharing also drives the business innovation by organizational learning. It is just the meaning of SCM that this business innovation chain is brought by sharing information and knowledge.

As Japanese manufactures shift production sites from Japan to overseas areas, among different overseas areas, and eventually back to Japan, logistics have globalize their processes in order to supply international and domestic demand. This study considers three factors for these shifts : cost, demand, and risk. Moreover, the current situation of Japanese manufactures' shifts occurred in the 1990's are analyzed.

The Large-Scale Retail Store Location Law was enacted in June 2000, which provides guidelines on determining the size of loading/unloading facilities. The determinant variable to the size of the facilities is the loading/unloading time of trucks. Therefore, the size of the facilities is greatly influenced by this loading/unloading time. The same law, however, is not clear on the process of obtaining this loading/unloading time of trucks. This study introduces a methodology on obtaining the variable loading/unloading time.

Recently, M&A between companies that manufacture similar products have been carried out quite often with the intention of improving efficiency. This trend has generated an allocation problem in the facilities, such as which products should be manufactured at which facilities. In this paper, I will address the product allocation problem in order to minimize the total distribution costs for a company that deal with export products and domestic sale products. And I proposed a mathematical formulation and heuristic algorithms for this problem. Finally I made an analysis of actual case data, and calculated the reduction costs by modifying the product allocation to facilities.

There have been a difference in the time of the number and both in Japan and Korea experienced “the bubble economy” likewise. Between these, a big change with both together freight quantities was seen. However, there is a very contrastive point in the change of the freight quantity of both. It in the other side, Japan where an intense change was seen to the freight quantity of Korea didn't change so intensely. In this research, it analyzes the cause.

The documents history of cross-border trade has approximately one thousand year, especially, after the Industrial Revolution the trade volume was accelerated. Recently Information Technology is applied to Customs and drayage systems. In Japan new trial to receive imported cargo within 48 hours from 72hours was commenced in 2003. On the other hand, USA started e-Customs from the standpoint of security chain management. e-Customs scheme is introduced slightly at the beginning and gradually enlarged in 5 years. Japan has to keep pace with e-Customs system of the U.S.A.

Is logistics in the world evolving on an integrated single form of paradigm, or will a different logistics continue to take place in a different region? This paper is intended to give clue to find an answer to the question. As a result of the numerous interviews with companies and public institutions, general differences were found in the propensity of logistics management towards structural issues in Europe and operational issues Japan; and in the degree of customer services, too little in Europe and too much in Japan. To face up to these differences and try to merge the strong points of Japanese management method with European logistics will contribute to establishing a common paradigm shared on a global scale.
