中文摘要：

RFID发现服务负责从供应链不同合作伙伴的信息服务中搜集与某个（些）物品相关的动态RFID事件,作为数据集.为了便于对发现服务获得的数据集进行可视化分析,本文给出了一种供应链建模技术.规约了发现服务获得的数据集,这种数据集描述了物品的移动、包装/解包装、加工制造;同时,采用P2P和并行处理技术,给出了一种新的分布式RFID发现服务;然后,基于Petri网提出了一种新的建模工具“SupplyNet”,并给出了构建SupplyNet的算法.算法分析和实验表明这种构建SupplyNet的算法具有较高的效率和可用性.

英文摘要：

RFID Discovery Service provides a means to find all dynamic RFID events related to certain objects as the data set,from different enterprises＇ information services. To facilitate visual analysis on the discovered data set, a modeling technology for supply chain is proposed.. The discovered data set of supply chains is specified, which includes the movement of! objects, ag- gregating with other objects or disaggregating from an integrity, and processing or transforming materials into new products. As well, an innovative distributed RFID Discovery Service is briefly introduced by combining technologies of P2P and parallel process- ing. Then,a Petri net based modeling tool ＂Supply-Net＂ is proposed, and the algorithm for constructing Supply-Net is given.Final- ly, analysis and experiments on our algorithm show its high efficiency and utility.
