供应链环境下RFID安全认证方案不仅要保证各节点的隐私安全,还应该满足供应链管理需求。针对现有方案存在不能同时兼顾两者的不足,提出一种基于"双重签名"的认证方案。标签的认证信息先后采用访问密钥和认证密钥进行双重签名生成,只有同时具备这两个密钥才能识别标签身份。该方案既可以实现标签在供应链内的安全传递,又能方便供应链的管理。分析表明,该方案较现有方案优势明显。  相似文献

Management of engineered-to-order (ETO) components and their related information is a challenging task due to the complexity of information and its flow. Different information items are generated, accessed and exchanged between different organizations and they must continually flow through design, production, construction, and operations and maintenance. Current manual and labor-intensive methods are inefficient; as a result, information is frequently incomplete, inaccurate or unavailable during the life-cycle of a facility. This paper provides a vision of intelligent components, which know their identities, locations and history, and communicate this information to their environments. It proposes streamlining information flow through supply chains by utilizing radio frequency identification (RFID) technology. To explore the technical feasibility of intelligent components, component-related information flow patterns in ETO supply chains were identified and analyzed. Requirements analysis and corresponding technology deployment and testing were performed for three types of ETO components through different life-cycle phases. These experiments demonstrated that it is technically feasible to have intelligent components in construction supply chains by using RFID technology; that status information can be collected automatically; and that maintenance information can be stored and retrieved during the service life of a facility.  相似文献

Nowadays, the cooperative intelligent transport systems are part of a largest system. Transportations are modal operations integrated in logistics and, logistics is the main process of the supply chain management. The supply chain strategic management as a simultaneous local and global value chain is a collaborative/cooperative organization of stakeholders, many times in co-opetition, to perform a service to the customers respecting the time, place, price and quality levels. The transportation, like other logistics operations must add value, which is achieved in this case through compression lead times and order fulfillments. The complex supplier's network and the distribution channels must be efficient and the integral visibility (monitoring and tracing) of supply chain is a significant source of competitive advantage. Nowadays, the competition is not discussed between companies but among supply chains. This paper aims to evidence the current and emerging manufacturing and logistics system challenges as a new field of opportunities for the automation and control systems research community. Furthermore, the paper forecasts the use of radio frequency identification (RFID) technologies integrated into an information and communication technologies (ICT) framework based on distributed artificial intelligence (DAI) supported by a multi-agent system (MAS), as the most value advantage of supply chain management (SCM) in a cooperative intelligent logistics systems. Logistical platforms (production or distribution) as nodes of added value of supplying and distribution networks are proposed as critical points of the visibility of the inventory, where these technological needs are more evident.  相似文献

When a company faces the global market, they would have to reengineer their processes and reorient their operation strategies, such as supply chain positioning strategy (SCPS) to benefit the most from a given situation. SCPS refers to actions taken by firms to respond to and satisfy customers' demand. The traditional concepts of production positioning strategy has been extended in this paper to develop various supply chain positioning strategies with a view that, for different production strategies, supply chain strategies should also be different. Obviously, each typical strategy has its advantages and limitations, and only fits for some certain scenarios. In this study, typical SCPSs have been defined, analyzed and classified. Supply chain dynamics and their impact on various strategies are also discussed. Subsequently, general integration approaches of the proposed strategies have been explored. Then, an approach for implementing SCPS in electronics industry is elaborated. It is shown that with integrated strategies, companies can get their desired optimal business values, even under great supply chain dynamics. It is expected that this method would be suitable for global organizations that has a need to cater to varying demands in different regions.  相似文献

Radio Frequency Identification (RFID) features high storage capacity, remote access, excellent data security, and multiple-tag reading. Hence, RFID technology attracts attention from various industries, especially the logistics and retail industries. Due to the swift development of technology and the trend of globalization, the logistics managers are assigned the task to integrate the supply chain via information technology such as RFID. The goal is to achieve information sharing and reduction of total cost, thus the operation efficiency can be improved and competitive advantage can be enhanced. Thus, this research would first identify the key factors of RFID technology development in the logistics and supply chain management. A complete set of five dimensions and 24 factors with a hierarchy structure is presented. The Fuzzy Delphi and Fuzzy Analytic Hierarchy Process methods are adopted for analysis. A structural procedure of RFID system establishment is also constructed based on the key dimensions and factors, with the expectation of establishing the RFID system in an effective and efficient manner. Then, based on the experience of Taiwanese government and industry, the sequence of companies for adopting the RFID technology is discussed. Thus, an integrated framework for the development of RFID technology, which includes the hierarchy of factors, structural procedure, and sequence of adoption, is presented in this research; and it can be applied in other scenarios after the users make some modifications according to their specific needs.  相似文献
