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

其中最重要的一点是很难掌握供应链上物品的当前信息。因此，为了满足顾客的需求，有必要保持多余的库存，这就产生了多余的成本。由于互联网的发展导致了全球范围内的交通运输，成本有上升的趋势。提出了一种数据载体型供应链管理方法，通过在生产和运输物品上附加射频识别标签，实现对生产和运输物品的高效管理。在数据载体型管理系统中，项目数据存储在分布式数据库中，实现了每台计算机自主向另一台计算机发送/接收数据的功能，以实现现有的业务流程。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，确认了带有rfid标签的物品可以在供应链上进行适当的管理和流动。还配备了使用蓝牙的基本数据收发技术，蓝牙是一种无线通信技术，通信距离远。开发了模拟蓝牙终端高效分配和收发数据管理的工具，以及蓝牙移动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.
