This paper is mainly about the development of u-warehouse management system by using RFID in SCM environment. We developed a web-based real-time u-warehouse management system centering to manufacture enterprises by analyzing the process before and after the adopting of RFID technologies in warehouse management, deducing the standard application process which adopts RFID technologies in SCM environment.

In this study, we offered a way that is to make warehouse industry clustered in Incheon port for getting competitive and high end value added activities like advanced port logistics center considering trend that is changing functions of port and importance of port-hinterland. For this, we studied the existing research about port cluster, the present condition of warehouse industry in Incheon port and importance of value-added logistics activities. Also, we offered needs to build a high value-added and integrated logistics center by examples of advanced port logistics center in Singapore, Netherlands(Rotterdam) and Hongkong. We get the questionnaires for gathering ideas of port logistics industry about to set integrated logistics centers by strategy we offered that is making warehouse logistics clustered.

  Forming central warehouses for a number of stores can save costs in the continuous review inventory model due to economy of scale and information sharing. In this paper, transportation costs are included in this inventory model. Hence, the tradeoff betw

  This paper addresses the allocation planning of the storage location in a warehouse system that the dedicated storage method is used. In the discrete finite time period model, the demands for storage location of products are dynamic for time periods. Th

RFID/USN is important infrastructure of the ubiquitous society. And so, It is various and practical research is attempted. These two base technology have physical characteristic and complement relationship. Like this relationship is applied Following example that is system research which manages warehouse stocks and conditions. First, We adhere RFID Tag at the Pallet of the warehouse and do identification goods. And then, It grasps the environment state information of stocks with sensor module which has Zigbee wireless communication function. From like this process RFID Tag information and jop-control command of sensor node also it is exposed to air. Therefore, We control sensor node in USN/RFID environment through the mobile device. And system design for the security Apply of the process is main purpose of this paper's. We propose the condition and function of the mobile device to the secondary. And We define the relation of the sensor node with RFID to be arranged to a warehouse. Finally, This paper is designed to find a trade-off of the following viewpoints. First, We offer suitable sensor-control information to a actual manager. Second, We offer RFID tag security approach to control the action of the sensor. Third, It increases the survivability of sensor node form.

This paper deals with the S/W development of web-based warehouse management system using ubiquitous RFID(Radio Frequency Identification). This S/W System supports the realtime inventory management and collaborative operations of relational companies in SCM. We expect to decrease the logistic cost and to upgrade the status of WMS and competitive power of company.

  This paper addresses the analysis of the travel distance and the number of storage location for storage location allocation methods in a warehouse system. The dedicated, randomized, combined and limited storage methods are considered. The combined and t

A number of stores can save costs by forming a centralized inventory system. The number and location of centralized warehouses can be determined in minimizing total costs and then these cost reductions should be allocated fairly to each store. If no group of stores feel that they are paying to subsidize to the complementary set of stores, then that cost allocation is in core. That is, all stores become better off by forming a group. This study shows that there does not exist the core in some examples. Hence, we suggest a framework for the cost allocation both of the case in which the core exists and the core does not exist.

Due to the complexity and stochastic nature of automated warehousing system, items are usually queued up at I/O point. We introduce a storage/retrieval policy : dual-command. We present quick approximations to queueing phenomena under these policies. It i

A centralized inventory system provides a number of stores with cost reduction, information sharing. To build centralized warehouses, two things should be considered: how many warehouses are required and where these are located. The number and location of centralized warehouses can be determined in minimizing total costs and then these cost reductions should be allocated fairly to each store. Since it is too time-intensive to find an optimal solution of minimizing total costs, this paper presents heuristics and compares its results with an optimal solution.

A number of stores can save costs by forming central warehouses. In this paper, transportation cost is included in the inventory model with the continuous review policy, namely, (Q,R) policy. The objective of this paper is to develop an efficient simulated annealing algorithm and heuristic for large-scale problems of determining the location and the number of central warehouses by minimizing total costs. Some computational results and suggestions for future research are also discussed.

The purpose of this study is to develop S/W of the web-based collaborative warehouse management system using RFID(Radio Frequency Identification). This S/W System supports the realtime inventory management and collaborative operations of relational companies in SCM. We look for benefits-reduce inventory levels, maxmize use of warehouse space, decrease the logistic cost, and increase competitive power of company, using this S/W

We consider an AS/RS(Automated Storage/ Retrieval System) which performs both of single and dual commands. The service times of single and dual commands are assumed to be differently distributed. Steady-state probabilities at the service completion epochs

Due to the complexity and stochastic nature of automated warehousing system, items are usually queued up at I/O point. We introduce a storage/retrieval policy : dual-command. We present quick approximations to queueing phenomena under these policies. It is assumed that the storage and retrieval arrrival pattern follow the same poisson process. We also assumed that storage queue and retrieval queue being operated separately. The approximation attempts are performed under the proposed storage/retrieval policies after we derive S/R machine travel time distributions.

Automated manufacturing systems are applied to shop floors as tools for increase of productivity and quality and the decrease of manufacturing lead times and industry accidents. One of the most important issue of the present day is the application of Internet. The development of Internet technologies makes manufacturing enterprises break spacial barriers between users and shop floors, and collect various field data in remote sites. In this research, an Internet-based remote control system for a small-sized automated storage and retrieval system is developed for the purpose of real-time monitoring and control of automatic production equipment. The developed system has a client-server architecture and sends real-time images of the automated storage and retrieval system to clients by an CCD camera connected to a server.

This paper considers automated storage and retrieval systems with double shuttle. We develop the travel time model based on the first come first service rule. We evaluate the performance of the double shuttle system working on the four command cycle.
