A Cyber Collaborative Protocol for Real-Time Communication and Control in Human-Robot-Sensor Work

Abstract

Real-time communication and control are essential parts of the Cyber Physical System (CPS) to optimize effective performance and reliability. To gain a sustainable competitive advantage with Automation 5.0, as needed in Work-of-the-Future, this article addresses the concept of real-time communication and control in the case of an agricultural work setting, along with a newly designed Cyber Collaborative Protocol, called CCP-RTC2. The developed protocol aims to minimize information delay and maximize JIN (Just In Need) information sharing, to enable collaborative decisions among system agents. Two experiments are conducted to compare the designed protocol’s performance in agricultural CPS against the current non-CPS practice. The results demonstrate that the CCP-RTC2 is superior compared with current practice in terms of information sharing in a normal operation scenario. When the system obtains an unplanned request, the CCP-RTC2 can integrate such a request to the original work plan while minimizing the system’s objective function (lower is better). Hence, the system has relatively smaller information delays, as well as better timely information shared with system agents that need it.

Digital Transition Methodology of a Warehouse in the Concept of Sustainable Development with an Industrial Case Study

“…The transition of logistics centers has changed with the emergence of the Industry 4.0 era [10]. These technologies are used in logistics operations by practitioners and academics in engineering and operations management to increase performance [12]. The warehouse can integrate 5G technology to schedule and route vehicles [13].…”

Smart Agriculture: IoT-based Greenhouse Monitoring System

“…The challenges are arranged into groups according to the characteristics they present, as seen in Figure 1. Concerns in this field are growing, a series of recent papers addressed the deployment of modern information and communication technologies in agriculture, for example [31][32] [33]. Our research collective has been dealing with this problem for some time, our concerns being more and more directed towards small farmers, basically in the western part of Romania [34][35].…”
