Development of A Ubiquitous Logistics Control System with Data Carrier for Autonomous Distributed Information Control

在物流领域，为了满足不同客户的需求，需要灵活的运输和库存控制方法。通过将无线通信的数据载体（rfid - id标签或具有蓝牙通信功能的移动设备）附加到物流物品上，提出了一种自主分布式物流控制信息系统。该系统能够高效、动态地管理物品流转。另外，物流企业的结构是灵活的，分布式企业的决策是自主的。在自主分布式物流控制信息系统中，针对控制功能，提出了一种以数据载体在实际时间内获取物品位置信息的通信方法。在该方法中，从到数据载体的距离估计位置信息。此外，还讨论了用于收集和管理这些分布式信息的用户界面。另一方面，针对调度功能，提出了一种子系统间的协商方法，以实现“协同通信层”，使整个系统在出现资源短缺问题时仍能保持高效。该协商方法通过交换修改后的解方案，使两个子系统都能得到满意的解。通过这些方法，给出了物流企业整体资源有效利用、鲁棒性高的基础。

In logistics fields, in order to satisfy various customers requirement, flexible transportation and inventory control method are desired. By attaching data carrier of wireless communication (RF-ID tag, or mobile device with Bluetooth communication function) to items in logistics, the autonomous distributed information system for logistics control are proposed. This system can manage the flow of the items efficiently and dynamically. Additionally structure of logistics companies in the logistics is flexible and distributed company make their decisions autonomously.In the autonomous distributed information system for logistics control, for control functions, a communication method in order to get locational information of an item with data carrier in practical time is proposed. In this method, from the distance to the data carrier, locational information is estimated. Additionally, a user interface in order to gather and manage those distributed information is discussed. On the other hand, for scheduling functions, a negotiation method between subsystems is proposed in order to realize "cooperative communication layer" which makes a whole system efficient in the case that problems (lack of resources) occurs in the system. This negotiation method make the solution that both subsystem is satisfied by exchanging a modified plan of solutions. By those methods, the base that whole resources in logistics companies are used effectively with high robustness is published.
