Warehouse management with lean and RFID application: a case study

This research presents the integration of lean production and radiofrequency identification (RFID) technology to improve the efficiency and effectiveness of warehouse management. More than ten million parts belonging to around 10,000 types in a distribution center were involved in this study. There are more than 10,000 storage and retrieval operations for hundreds of part types on a daily basis. Value stream mapping was used to draw current state mapping and future state mapping (with lean management and RFID) with material flow, information flow, and time flow. Preliminary experiments showed that the average reading rate of electric forklift and hydraulic cart are 99.3 and 99.1 % by fixed ultra-high frequency RFID readers with antenna installed at the receiving/shipping dock and passive tags mounted on box/pallet. The processing time of data transmitting to warehouse management system at receiving and shipping docks was reduced by 99 and 89 %, respectively. The total operation time from current stage to future stage with only lean can be saved by 79 %. With further integration of RFID to lean, the total operation time can be saved by 87 %. Moreover, performance on saving total operation time can be enhanced to 91 % with cross-docking. The benefit of using RFID in the warehouse management is realized and promoted.

Modular Configuration of an RFID-based Hybrid Control Architecture for a Situational Shop Floor Control

Nowadays, producing companies act in a turbulent environment, which is caused by the globalization of the economy and the continuous shift from seller markets to buyer markets. One central aspect is the demand for customized products at short delivery times and reasonable costs. In this context, shop floor control becomes more and more important and therefore, the complexity of its purposes increases. However, current shop floor information, which is indispensable for a targeted execution of these purposes, is often not available. The RFID (Radio Frequency Identification) technology enables an adequate and situational shop floor control. Since the integration and capabilities of RFID depends on specific framework conditions (e.g. forms of organization), an approach for a modular configuration of an RFID-based hybrid control architecture, that separates control efforts into centralized and decentralized control elements, is motivated. Finally, this approach could be implemented to a use case of a German automotive seat supplier.

A novel stable cluster-based protocol for heterogeneous RFID enhanced wireless sensor networks

By integrating Radio Frequency Identification (RFID) technology with Wireless Sensor Networks (WSN), it is feasible to route RFID data from readers and RFID enhanced wireless sensor nodes (WSN) into base-stations through existing WSN clustering protocols. WSNs for reducing energy consumption and improving stability period can use clustering algorithms. Clustering sensor nodes are a useful topology control technique, but these algorithms are not always suitable for heterogeneous WSNs. Previous constructive algorithms, such as LEACH and SEP are not always stable in heterogeneous WSNs. They are designed without regard to appropriate parameters, such as remaining power and confidence value of the nodes for WSNs. In this paper we suggest and introduce a novel stable heterogeneous cluster-based protocol with cluster member bounds for heterogeneous RFID enhanced WSNs, which called SHCP. In SHCP, the probability of cluster-heads (CHs) election are weighted by the primary energy of a node relative to that of other nodes in the network and cluster formation, based on nodes current energy, numbers of current members which belong to a CH, distance between CHs and nodes and distance between CHs and base-station. Our conclusion shows the simulation results show SHCP achieves longer stability time until the first node dies (FND), half nodes die (HND) and improves energy utilization in WSNs.

Integrating Radio Frequency Identification into the piGUI System to Recognise Sampling Bias and Detect Feeding Behaviour

A machine vision system was developed to determine the live weight and growth rate of groups of pigs. During development, it was important to determine whether the sampling method had potential to cause bias and subsequent error in the daily weight estimates calculated by the system. Sampling bias can occur toward certain pigs because of their appearance or the frequency and duration in which they reside in the pen-region beneath the camera. To determine whether these forms of bias could occur, radio frequency identification (RFID) was integrated into the system to monitor the attendance of individual pigs in the pen-region observed by the camera. Test results indicated that both forms of bias had occurred as a result of the system’s filter settings and the installation position. As the system observed a single feeder space, the opportunity arose to analyse the data further and determine whether the feeding behaviour of individual animals could be recovered from their attendance at the feeder. Preliminary findings indicate that the attendance recorded by the RFID system at the feeder is related to weight gain and that attendance might be useful in detecting feeder demand and out of feed events. In addition, it is believed that the RFID-recorded interactions between pigs at the feeder may provide a novel way of automatically recording competitive behaviour between individual animals in a group. Continuously identifying individual pigs at the feeder helps to fine tune the vision systems parameters to overcome bias related issues concerning layout and sampling. Additional information can be gained by the RFID system which prompts further investigation.

Supply chain management with lean production and RFID application: A case study

► This research applies lean production and RFID technology to a supply chain. ► Value stream mapping is used to draw current and future state mapping. ► Total operation time can be saved by 81% using lean production and RFID. ► The return-on-investment is 2.6 indicating a worthwhile investment of lean and RFID. This study applies lean production and radio frequency identification (RFID) technologies to improve the efficiency and effectiveness of supply chain management. In this study, a three-tier spare parts supply chain with inefficient transportation, storage and retrieval operations is investigated. Value Stream Mapping (VSM) is used to draw current state mapping and future state mapping (with lean production and RFID) with material, information, and time flows. Preliminary experiments showed that the total operation time can be saved by 81% from current stage to future stage with the integration of RFID and lean. Moreover, the saving in total operation time can be enhanced to 89% with cross docking. In addition, utilizing RFID technology, the cost of labors can be significantly reduced while maintaining current service capacity at the members in the studied supply chain. Return-on-investment (ROI) analysis shows that the proposed method is both effective and feasible.

A two-factor authentication system using Radio Frequency Identification and watermarking technology

Counterfeiting has been growing at an alarming rate worldwide. The increasing number of counterfeit products has penetrated into various industries, especially the luxury goods industry. Numerous anti-counterfeit and product authentication technologies are available to combat this problem. At present, the verification principle in product authentication mainly relies on optical detection and security feature identification which require human experts or machines to determine the product's genuineness. As a result, the current approach to product authentication presents formidable challenges to customers in determining the product's authenticity. Attempted to address the challenges, this paper proposes a Watermark-RFID based Self-validation System (WARDS) that provides a self-validation and two-factor authentication approach through integration of Radio Frequency Identification (RFID) and watermark technology by means of a mobile platform. The system architecture and a framework for development of WARDS are presented. Critical issues at different stages of constructing WARDS in organizations are identified. Furthermore, the capability, benefits and advantages of using the proposed system in combating counterfeiting problems are illustrated in the findings of a trial implementation presented in this paper.

For the different requirement of identification granularity and manufacturing process information the parts are divided into three classes and identified with corresponding technology. The application result shows the production efficiency and quality is improved; the synchronization of logistics and information flow in manufacture is enhanced.

Optimizing the positioning and technological choices of RFID elements for aircraft part identification

This paper concerns the integration of RFID (Radio Frequency IDentification) technologies in helicopters. A global RFID system, including RFID tags (passive, battery assisted and active), reading modules and data concentrator, will be embedded in helicopters. Such an integration requires a positioning model, which must consider technological choices of the on-board components. The proposed approach combines an optimization model and a physical model to determine an optimal covering of each tag by at least one reading module. This covering is based on radio wave propagation. The optimization model is derived from a location model with specific constraints. Experimental results validate the approach in an industrial context.

Achieving sustained competitive advantage by integrating ECR, RFID and visibility in retail supply chains: a conceptual framework

While efficient consumer response (ECR), radio frequency identification (RFID) and supply chain visibility are concepts that have received academic and practitioner attention, the benefits of integration have not been considered in any detail. Based on a systematic review of literature, the findings suggest that designing retail supply chains to integrate the concepts of RFID, ECR and visibility presents opportunities for sustained competitive advantage. The contribution made by this article is the formulation of six research propositions which propose that the integration of ECR, RFID and supply chain visibility may be considered as a strategic capability within retail supply networks. By adopting the theoretical lens of the resource-based view of the firm, research propositions examining integration as per the characteristics of valuable, rare, imperfectly mobile, not imitable and not substitutable are developed.

“Green” wideband log-spiral antenna for RFID sensing and wireless applications

The novel idea of integrating Radio Frequency Identification (RFID) with sensors along with other wireless applications by using single tag antenna is implemented, by fabricating proposed antenna using state-of-the-art inkjet printing technology on commercially available paper substrates. For the first time, a parametric analysis is performed for realization of the planar log-spiral antenna on paper for operational range from 0.8 to 3.0 GHz, which also exhibits excellent coverage throughout numerous RFID Industrial, Scientific and Medical (ISM) bands, and for other wireless applications. The ANSYS HFSSTM tool is used to design and predict the performance of the proposed antenna in terms of radiation pattern and input impedance.

Security Threats and Challenges for RFID and WSN Integration

Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN) are the combined technologies that will spread in the near future to enter all of our everyday activities. However, the security of these technologies is very much vulnerable. Adding some security measures to small computation powered devices that cannot handle the available security algorithms is considered a challenge. However, even low powered devices must be protected in ways that will present sufficient computational challenges to adversaries. This paper introduces suggested steps to build a secure protocol for the combined RFID and WSN technology application systems. Moreover, it demonstrates the possible attacks and threats on these combined technologies by analyzing their system environment and finally it discusses the possible threats that may occur.

Cross-layer architecture of impulse-based ultra wideband to support the integration of Radio Frequency Identification and wireless sensor network infrastructures

Many research studies have recently proposed the use of Impulse Radio based ultra-wideband technology for passive and active radio frequency identification systems as well as for wireless sensor networks because of its numerous advantages. To harness these advantages at the physical-layer level of design, cross-layer architecture can be used to integrate different wireless short-range requirements into a smart wireless-tagged architecture. Adaptive transmission algorithm has been studied to show the trade-off flexibility between different specific quality of service requirements and transmission rate parameters at the physical-layer level in varied distance scenarios. This type of dynamic optimization and reconfiguration leads to the cross-layer design proposal introduced in this paper. The results of the theoretical and simulated analyses as well as the dedicated experimental design and implementations prove the validity of the proposed architecture.

This paper deals with a system of integration of Radio Frequency Identification (RFID) and communication technologies for solid waste bin and truck monitoring system. RFID, GPS, GPRS and GIS along with camera technologies have been integrated and developed the bin and truck intelligent monitoring system. A new kind of integrated theoretical framework, hardware architecture and interface algorithm has been introduced between the technologies for the successful implementation of the proposed system.

The results showed that the real-time image processing, histogram analysis, waste estimation and other bin information have been displayed in the GUI of the monitoring system. The real-time test and experimental results showed that the performance of the developed system was stable and satisfied the monitoring system with high practicability and validity.

Energy Efficient In-network RFID Data Filtering Scheme in Wireless Sensor Networks

RFID (Radio frequency identification) and wireless sensor networks are backbone technologies for pervasive environments. In integration of RFID and WSN, RFID data uses WSN protocols for multi-hop communications. Energy is a critical issue in WSNs; however, RFID data contains a lot of duplication. These duplications can be eliminated at the base station, but unnecessary transmissions of duplicate data within the network still occurs, which consumes nodes’ energy and affects network lifetime. In this paper, we propose an in-network RFID data filtering scheme that efficiently eliminates the duplicate data. For this we use a clustering mechanism where cluster heads eliminate duplicate data and forward filtered data towards the base station. Simulation results prove that our approach saves considerable amounts of energy in terms of communication and computational cost, compared to existing filtering schemes.

Integration of RFID and Web Service for Assisted Living

The number of people over 65 years old throughout most stable and prosperous countries in the world is increasing. Availability of their care in their own homes is imperative because of the economic reasons and their choices where to live (World Health Organization, Definition of an older or elderly person. http://www.who.int/healthinfo/survey/ageingdefnolder/en/ ; EQUIP-European Framework for Qualifications in Home Care Services for Older People, http://www.equip-project.com ; Salonen, 2009). "Recent advancement in wireless communications and electronics has enabled the development of low-cost sensor networks. The sensor networks can be utilized in various application areas." (Akyildiz, et al. 2002) These two statements show that there is a great promise in wireless technology and utilizing it in assisted living might be very beneficial to the elderly people. In this paper, we propose software architecture called Location Windows Service (LWS) which integrates the Radio Frequency Identification (RFID) technology and the web service to build an assisted living system for elderly people at home. This architecture monitors the location of elderly people without interfering in their daily activities. Location information messages that are generated as the elderly move from room to room indicate that the elderly person is fit and healthy and going about their normal life. The communication must be timely enough to follow elderly people as they move from room to room without missing a location. Unacknowledged publishing, subscription filtering and short location change messages are also included in this software model to reduce the network traffic in large homes. We propose some defense schemes being applied to the network environment of the assisted living system to prevent any external attacks.

An infrastructure for smart hospitals

In healthcare facilities most of the daily activities require strict coordination between clinicians, who often operate under heavy workloads and minimal workforce conditions in environments filled with increasingly complex technology. Ubiquitous Computing applications constitute a suitable solution for both reducing medical costs and improving patient safety by better supporting clinical processes. In this study we introduce an intelligent infrastructure for smart hospitals which implements basic services to optimize medical staff/patient interactions and grants ubiquitous and transparent access to clinical data stored in standard clinical databases. This infrastructure relies on the integration of Radio Frequency IDentification (RFID) and photosensor technologies to identify, locate and track clinicians and patients equipped with mobile devices and wearable RFID tags.

Research on RFID Integration Middleware for Enterprise Information System

Radio Frequency Identification (RFID) is a promising technology for automated non-line-of-sight object identification. Traditional research of RFID middleware does not concern RFID related integration with enterprise information systems. Considering the requirements of RFID middleware and business process integration with enterprise information systems, an integration framework for RFID middleware based on business process rule and data stream technologies are introduced. Main modules of the RFID integration middleware, such as devices monitoring, data management, XML business documents exchange, business process control and RFID event management, are designed and discussed in detail. The semantic definition of the complex RFID event and RFID event classification are presented. A real-time scheduling strategy of RFID event which is based on the buffer and priority queue, can process the concurrent RFID events. Application system based on RFID is realized to control the business process through RFID events.

SAPCC1G2: a mutual authentication protocol promote the security of RFID and WSN integration system

With the integration of radio frequency identification (RFID) and wireless sensor network, these two technologies are used more and more extensively. The security issues of the integration system are increasingly concerned by people, and the security of RFID is the most critical part of the integration system. EPC C1G2 is a standard for low-cost RFID air interface. The authentication processes of most existing RFID systems are not compatible with the EPC C1G2 standard. This paper proposes a secure authentication protocol conforming to EPC C1G2, called SAPCC1G2, which is compatible with existing RFID reader and achieves the data dynamic updating in transmission process. The new scheme can defend typical attacks such as tracking, replaying, eavesdropping, cloning and denial of service attack. It has higher security and quicker authentication speed, so it has advantages over existing peers. It can promote the security and the efficiency of the authentication process for the integrated system.
