“…The real system consists of the material, workers, management, computation units, and the sensors which are implemented to observe the behaviour of the system under study. The measuring unit handles the streams of sensory data and the estimation of processing time and material handling time of the system under study, details of which are in our previous works Chowdhury et al 2020;and Chowdhury et al 2021). In addition, the implementation of DDDAS paradigm in this framework and the fidelity level optimization of the dynamic decision making is discussed here .…”

Survival and thrift in a globally competitive market strongly depend on the improvement of production quality while monitoring the pricing for grafting nurseries. Real-time monitoring of irrigation quality is a necessary yet cumbersome task for propagation facilities. Even for indoor facilities with automatic irrigation systems, this task remains bothersome due to the large greenhouses. The main goal of this paper is to propose an irrigation monitoring system to increase production productivity by minimizing the time workers spend on responding to irrigation monitoring calls. Here, a two-stage data-driven approach is proposed, where the traveling salesman model is implied on a reduced spatiotemporal network provided by Bayesian analysis to optimize workers routing for irrigation monitoring. The proposed approach is the final piece of a dynamic data-driven simulation-based optimization framework. The results over synthetic data demonstrate a potential reduction of 11.60% in traveled distance per worker per call.

“…Radio Frequency Identification and Detection (RFID) [1] is a well-consolidated technology successfully adopted for different applications [2][3][4][5][6]. In particular, RFID technology has many applications ranging from tracking foods and goods to the security of restricted areas [7][8][9][10][11][12][13][14][15][16]. Researchers are concentrated on finding solutions to further reduce the cost and in particular to improve the operating range [17][18][19][20][21][22], which for standard RFID is only a few centimeters.…”

Development of Enhanced Range, High Q, Passive, Chipless RFID Tags for Continuous Monitoring and Sensing Applications

A high Q planar chipless RFID tag with high sensitivity is proposed for communication applications. In particular, the tag structure is composed of a complementary spiral structure (CSS) that is able to provide high sensitivity and compactness. A semi analytical formula for the design of a single bit tag is derived, and the behaviour of the CSS is analysed for different dielectric substrates. Different tags, composed of up to a set of eight resonators, have been numerically and experimentally assessed. In particular, a system prototype composed of a reader and a set of tags are fabricated and experimentally assessed as a proof of concept. The system provided an operative range of tens of centimetres (a maximum operative range of 65 cm). The obtained results are quite promising and the agreement between simulated and measured results are found to be good.

The idea of Industry 4.0 is a stage of revolution in terms of new solutions and advanced technology, as well as artificial intelligence. Micro and macroeconomic factors generate the need to modify logistics and production processes in enterprises. One of the changes is the organization of warehouse management. The aim of the article is to indicate the possibility of using RFID technology in conjunction with Laser Telemetry in the location of objects in space along with the visualization of this location. In addition, the study aims to merge passive RFID technology with laser scanning to produce a system that can identify and locate objects in a virtual Computer-Aided Design (CAD)—based 3Dimensional (3D) environment. The described case study is the result of research conducted as part of the implementation project. This paper describes the steps to be taken and the creation of a system that will use RFID technology and that will enable the identification of objects in the space of computer systems. For this purpose, it was possible to create a system that will identify objects using RFID and Laser Telemetry in 3D space.
