“…In this context, mature technologies such as RFID, capable of facilitating logistics time savings, can still extend their capabilities and be useful in big data environments [26], among other reasons, because the capabilities of the tags associated with them are also expanding [27] and the signal acquisition systems skills [28]. This option is compatible with the technological advances in indoor assets location [29] and allows the initiation of practical steps towards a digital warehouse in an immediate operation way.…”

Through the construction of parametric simulation models in which possible storage space distributions and positioning logics are also considered as variables, it is possible to build scenarios that allow analyzing the changing reality of storage needs in order to minimize material movements in each case, optimize internal transportation, and increase the efficiency of production processes. This article shows a particular analysis of a restricted storage space in height, typical to when it comes to logistics associated with raw material in a “big bag” format made of recycled and easily deteriorated material. In conjunction, a location management solution based on passive RFID (radio-frequency identification) tags has been chosen. The process is carried out through simulations with object-oriented discrete event software, where the optimization of the internal transport associated with the layout is carried out considering network theory to define the shortest path between warehouse nodes. The combination of both approaches allows, on the one hand, the evaluation of alternatives in terms of distribution and positioning logics, while the implemented system enables the possibility of making agile changes in the physical configuration of this type of storage space.

“…Due to the low cost and ease of implementation, radio frequency identification (RFID) has been identified as an enabling technology for Industry 5.0 [1]. RFID tags have been utilised in numerous applications including supply-chain management [3], logistics [4] and location positioning [5,6]. Although active and semi-active RFID tags provide greater range and location accuracy [7,8], they are more expensive and require an on-board power source.…”

Radio frequency identification (RFID) is a cost-effective method to support the Industrial Internet of Things (IIoT) and is an enabling technology for Industry 5.0. The use of RFID is particularly suited to IIoT as it does not require a line of sight for communication and can be retroactively affixed to non-smart items. However, RFID communication is affected by the properties of the material the tag is affixed to, specifically the material permittivity. Metal is commonly present in smart factory environments and supply chains and impedes RFID communication. A suitable tag design is required to accommodate these challenges and ensure resilience for Industry 5.0 applications. The research presented in this paper has assessed the communication performance of RFID antenna designs with and without metal present beneath the tag. The RFID tag designs that performed reliably in the simulation were manufactured, and their read range was tested on materials of varying relative permittivity and thickness to represent MP and NMP scenarios. The results have verified the robustness of “Cyber” to “Physical” designs and provide recommendations to support practitioner IIoT tag selection.

“…Studying the moving track and staying time of the target at the key points in the protection area in the security system plays an important role in mining the behavior characteristics of the target and evaluating its threat degree. e moving track of the target in the protection area can be obtained through RFID positioning technology [2,3]. It is helpful to analyze the target behavior pattern by analyzing the target trajectory and mining the abnormal trajectory [4,5].…”

In the security system, transforming a large number of collected target trajectories into semantic trajectories with a less volume and high quality and mining their frequent patterns are helpful to analyze the target behavior patterns, identify hazard sources, and enhance the internal prevention, and control of the security system. Aiming at the limitation of semantic trace frequent pattern mining method defined by precise stay time in practical application scenarios, a fuzzy semantic trace frequent pattern mining method is proposed. Firstly, the membership function of fuzzy stay time is defined, so the stay time of the target at the stay point is fuzzified, and the fuzzy semantic trajectory is obtained. Then, a fuzzy semantic trajectory frequent pattern mining algorithm FST-FPM (fuzzy semantic trajectory frequent pattern mining) is proposed. The FST-FPM algorithm is experimentally verified on the Geolife public dataset and the self-collected RFID positioning dataset. The experimental results show that FST-FPM algorithm can mine frequent patterns of fuzzy semantic trajectories on Geolife dataset and RFID positioning dataset, and the running time is reduced by more than 10% compared with classical PrefixSpan algorithm, PrefixSpan-x algorithm, and LFFT2 algorithm.
