EPCglobal管理委员会成员一致认为:EPC作为条码的延伸和补充,丰富了原有的以商品条码为基础的全球统一标识系统,为供应链的高效控制和管理提供了前所未有的、较为完善的解决方案。EPC与条码从不同侧面满足客户需求,所以EPC不会取代条码,二者将长期共存。 相似文献

EPCglobal提出了EPC网络的全球标准,旨在促进EPC网络在全球范围内更广泛的应用。ONS解析服务作为EPCglobal框架中一个重要部分,设计其系统架构以实现其寻址、解析的功能十分重要。对于企业而言,搭建自有的ONS系统,能更好地应用EPC网络,从而在产业的IT建设上快人一步。针对此目的,利用Bind软件对服务器进行配置,提出并搭建了一个三级的ONS解析系统。研究结果实现了ONS解析功能。用户可以通过ONS解析服务查询出EPCIS地址,进而获取详细的EPC信息。 相似文献

为了解决物联网中EPCglobal框架中不同标签信息的处理问题,以及EPC标签和传统条码的数据兼容问题,提出一种基于EPCglobal框架的标签信息处理中间件。通过对标签存储结构和编码的研究,设计二进制EPC编码、EPC URI(Uniform Resource Identifier)和GS1条码的互相转换模块。采用对标签软硬件过滤的方法和对标签事件生成的研究,完善并实现EPCglobal标签处理中间件。测试结果表明,中间件很好地解决了从底层标签读取到标签事件生成上报整个流程的处理问题,在物联网中更全面、更兼容。 相似文献

Radio frequency Identification (RFID) systems are used to identify remote objects equipped with RFID tags by wireless scanning without manual intervention. Recently, EPCglobal proposed the Electronic Product Code (EPC) that is a coding scheme considered to be a possible successor to bar-code with added functionalities. In RFID-based applications where RFID tags are used to identify and track tagged objects, an RFID tag emits its EPC in plaintext. This makes the tag inevitably vulnerable to cloning attacks as well as information leakage and password disclosure. In this paper, we propose a novel anti-cloning method in accordance with the EPCglobal Class-1 Generation-2 (C1G2) standard. Our method only uses functions that can be supported by the standard and abides by the communication flow of the standard. The method is also secure against threats such as information leakage and password disclosure. 相似文献

Enterprise resource planning (ERP) and supply chain management (SCM) represent important information technology investment options for operation or IT managers, and have been acclaimed in the practitioner and academic literature for their potential to improve business performance. The purpose of this article is to provide further insights into the adoption of ERP systems and the impacts on firm competence in SCM. We propose a model featuring ERP benefits to firm competences in supply chain management. We also hypothesize that three constructs of ERP benefits positively impact firm competences in SCM. To clarify the relationships among these constructs, structural equation model (SEM) is conducted to examine the model fit and nine hypotheses. The SEM results clearly demonstrate that there exist close interrelations among the benefits of implementing ERP systems and firm competences in SCM. The data from Taiwanese IT firms was collected through interviewing of experts and surveys. The results provide empirical evidence that the beneficial impacts of ERP on the supply chain do lead to better overall SCM competence. That evidence confirms that operational benefits, business process and management benefits, and strategic IT planning benefits of ERP in turn enhance firm competences of SCM in operational process integration, customer and relationship integration, and planning and control process integration. 相似文献

The development of information technology has rapidly changed the logistics industry. RFID has become more and more important in the context of supply chain management (SCM), and implementation of RFID in SCM brings with it the potential to manage the information flow and to support communication and collaboration along the supply chain. This study was conducted to build a relation model, which is a structural model, to identify the effects of introducing RFID into the supply chain of the food and beverage industry in Korea. The supply chain of the food and beverage industry was divided into five activities: procurement, production, transport, sale, warehousing, and administration. This study was based on the premise that RFID will be embedded in a transport box or pallet circulated in the SC. The model showed that SC activities have positive relationships through the RFID system, and the introduction of RFID promotes information interchanges between SC activities, which in turn enable the coordination and consolidation of a total SCM. From the results of this study, it is expected that the RFID system does not only enable the SC partners to improve their utilities but also promotes the efficiency of SCM as a whole. This is meaningful considering that there is still a controversy regarding the effects of RFID on SCM. 相似文献

在分析EPCglobal UHF class1 generation2和基于DFSA协议的高速标签识别算法的基础上,采用位隙FSA协议标签响应标志位隙的设置方法,通过在标签上设置一个组位隙响应标志字,提出了一种EPC Gen2 标准下的RFID标签分组多位隙并行识别协议GMBPIP,设计了一条新的分组查询命令和基于DFSA的多组标签并行识别协议流程,从理论上了分析GMBPIP协议的性能,并使用EPC Gen2 标准协议时间参数进行了仿真实验。结果表明,GMBPIP协议在不增加标签太多计算负担的情况下,能够在EPC Gen2标准下有效降低时隙空闲率和冲突率,提高了标签的识别率、时隙利用率;平均识别率不仅突破了帧时隙ALOHA协议最高36.8%的瓶颈,而且高于目前文献所述同类算法的性能指标,达到了70.95%~81.61%。GMBPIP可以作为低成本RFID系统高速识别大量被动标签的支撑协议。 相似文献
