A Flexible Management Method of supply Chain by Using Logistics Information with RF-ID Tag

其中最重要的一点是难以掌握供应链上物品的当前信息。因此，为了满足客户的需求，有必要保持超额库存，这意味着超额成本。由于互联网的发展，全球范围内的运输成本也趋于增加，为了对生产和运输中的物品进行有效的管理，我们提出了数据载体型的供应链管理方法，即在物品上贴上RFID标签。在项目数据被存储在分布式数据库中的数据载体型管理系统中，为了实现现有的业务过程，实现每个计算机自主地向/从另一计算机发送/接收数据的功能。开发了具有IF-ID标签读写功能的原型系统。从原型系统的行为来看，可以确认带有RFID标签的物品可以在供应链上进行适当的管理和流动，并具备使用蓝牙这种具有更远通信距离的无线通信技术进行数据发送/接收的基本技术。开发了模拟蓝牙终端有效分配和管理发送/接收数据的工具以及当蓝牙移动的终端移动到通信区域时通过蓝牙自动发送/接收数据的信息系统。

One of the most important things is the difficulty to grasp current information of items on supply chain. Therefore, it is necessary to keep excess stock in order to satisfy customers' demands, and it reads excess cost. Because advance of internet caused transportation on all over the world, the cost had tended to be increasing.We proposed data-carrier type management method of supply chain for efficient management of items under producing and transporting by attaching RF-ID tags to them. The function that each computer autonomously sends/receives data to/from another computers is implemented for realizing the existing business procedures in a data-carrier type management system where item data are stored in distributed databases. The prototype system is developed to which is equipped the function and functions of read/write of IF-ID tags. From behaviors of the prototype system, it is confirmed that items with RF-ID tags can be appropriately managed and flowed on supply chain.Basic technologies of data sending/receiving using Bluetooth, which is a wireless communication technique and has farer communication distance, is also equipped. The tool which simulates efficient allocation of Bluetooth terminals and manages send/received data, and a information system which sends/receives data automatically through Bluetooth when Bluetooth mobile terminals move to communication areas are developed.
