In emerging Industrial Cyber-Physical Systems (ICPSs), the joint design of communication and control subsystems is essential, as these sub-systems are interconnected. In this paper, we study the joint design problem of an eventtriggered control and an energy-efficient resource allocation in a fifth generation (5G) wireless network. We formally state the problem as a multi-objective optimization one, aiming to minimize the number of updates on the actuators' input and the power consumption in the downlink transmission. To address the problem, we propose a model-free hierarchical reinforcement learning approach with uniformly ultimate boundedness stability guarantee that learns four policies simultaneously. These policies contain an update time policy on the actuators' input, a control policy, and energy-efficient sub-carrier and power allocation policies. Our simulation results show that the proposed approach can properly control a simulated ICPS and significantly decrease the number of updates on the actuators' input as well as the downlink power consumption.

“…The authors mention the use of MBSE, which can be supported by SysML or Architecture Description Language (ADL). Within the ADL family, Liu et al use the architecture analysis and design language (AADL) (Liu et al 2018;Liu and Wu, 2019). Attarzadeh-Niaki and Sander propose the For-SyDe framework, relying on SystemC language to model and simulate complex systems (Attarzadeh-Niaki and Sander 2016), and Graja et al propose a survey on CPS modelling techniques (Graja, Kallel, Guermouche, Cheikhrouhou & Hadj Kacem, 2018).…”

The fourth industrial revolution is shaping a new industrial landscape. A variety of technologies related to software, information and communication technologies embody a ubiquitous digital and connectivity era. These technologies enable the creation of new products with the integration of connectivity, data collection and processing capacities which require combining engineering disciplines. Increasing product multidisciplinarity compels companies to adapt their product development practices. The scientific literature offers a variety of concepts and techniques to support multidisciplinary product development. This paper seeks to organize the landscape of concepts and techniques available for multidisciplinary product development. An extensive literature review was conducted, and 236 concepts and techniques were identified. Multidisciplinary products of interest deal with both software and hardware development and can be encountered through the denominations of cyber-physical systems, mechatronics and smart products and systems. An in-depth analysis led to the classification and mapping, for each product denomination, of the concepts and techniques available to support their development. The classification relies on a four-level model paired with a decision tree to thoroughly sort the variety of concepts and techniques into the approach, process, method, and tool levels. The mapping between the sorted concepts and techniques enabled the generation of graphical representations called cartographies. These cartographies serve to support companies’ transformation towards the fourth industrial revolution from the product development perspective by giving a general overview of the related literature, and guiding them in the identification of the most suitable approaches, processes, methods and tools.

“…However, in addition to packet drops, there exist many other features of wireless communication, such as the delay and limited resources, which make a direct impact on the stability and performance of control sub-systems. To deal with these interconnections between the control and communication sub-systems, the joint design method is taken in ICPSs [6,14,15,16]. However, developing an analytical model of all control and network features is a fundamental challenge to this method.…”
