“…For researchers, although there are currently methods to develop the capabilities of reinforcement learning in individual tasks, there is still a lack of understanding and experience in how to construct intelligent systems that integrate these functionalities, relying on expert knowledge for discussions on research problems [50,51]. A key open question is what the best overall organizational method for multiagent systems is: homogeneous nonmodular systems [52]; fixed, static modular systems [53]; dynamically reconfigurable modular systems over time [54]; or other types of systems. In addition to the organizational methods, there are challenges in the transformation and coexistence of alternative knowledge representation approaches, such as symbolic, statistical, neural, and distributed representations [55], because the different representation techniques vary in their expressiveness, computational efficiency, and interpretability.…”

Extensive research has been carried out on reinforcement learning methods. The core idea of reinforcement learning is to learn methods by means of trial and error, and it has been successfully applied to robotics, autonomous driving, gaming, healthcare, resource management, and other fields. However, when building reinforcement learning solutions at the edge, not only are there the challenges of data-hungry and insufficient computational resources but also there is the difficulty of a single reinforcement learning method to meet the requirements of the model in terms of efficiency, generalization, robustness, and so on. These solutions rely on expert knowledge for the design of edge-side integrated reinforcement learning methods, and they lack high-level system architecture design to support their wider generalization and application. Therefore, in this paper, instead of surveying reinforcement learning systems, we survey the most commonly used options for each part of the architecture from the point of view of integrated application. We present the characteristics of traditional reinforcement learning in several aspects and design a corresponding integration framework based on them. In this process, we show a complete primer on the design of reinforcement learning architectures while also demonstrating the flexibility of the various parts of the architecture to be adapted to the characteristics of different edge tasks. Overall, reinforcement learning has become an important tool in intelligent decision making, but it still faces many challenges in the practical application in edge computing. The aim of this paper is to provide researchers and practitioners with a new, integrated perspective to better understand and apply reinforcement learning in edge decision-making tasks.

“…Self-adaptation issues in embedded software have been investigated across different areas of software engineering, such as requirements engineering [1][2][3][4], software architecture [5][6][7][8][9][10], middleware architectures [11][12][13][14], component-based development [15][16][17], model-driven development [18][19][20][21] and goal-driven models [22][23][24][25]. The majority of these works have been isolated initiatives.…”

The main objective of this work is the design and implementation of self-adaptive capabilities in wireless sensors by applying control engineering and model-based design methodologies. It has been addressed the problem related to the changes in the flow of data packets through the network connection and the excess energy consumption that this causes in these devices. To design the solution, a systemic characterization of the scheduling and execution process of embedded tasks on the device has been carried out. This means defining cause-effect relationships in the system and its modelling theoretically and/or experimentally. In turn, these models facilitate the design of control strategies to improve the dynamic behavior of the system. As a solution, a self-adaptation strategy based on feedforward control algorithm has been designed and developed, which has been applied to improve the dynamic behavior and resource consumption. The developed solution has been satisfactorily evaluated experimentally.

“…Those services are used to adapt and generate configurations. Connecting interfaces of different services from various systems for local reconfiguration is called Service-Oriented Reconfiguration (SoR) [52]. To adapt a system, SoR is in charge of blueprints that describe the connection abilities between potential services.…”

Production systems are changing in many aspects on the way to a Factory of the Future, including the level of automation and communication between components. Besides all benefits, this evolution raises the amount, effect and type of anomalies and unforeseen behavior to a new level of complexity. Thus, new detection and mitigation concepts are required. Based on a use-case dealing with a distributed transportation system for production environments, this paper describes the different sources of possible anomalies with the same effect, anomaly detection methods and related mitigation techniques. Depending on the identified anomaly, the FoF should react accordingly, such as fleet or AGV reconfiguration, strong authentication and access control or a deletion of adversarial noises. In this paper, different types of mitigation actions are described that support the fleet in overcoming the effect of the anomaly or preventing them in the future. A concept to select the most appreciate mitigation method is presented, where the detection of the correct source of the anomaly is key. This paper shows how various techniques can work together to gain a holistic view on anomalies in the Factory of the Future for selecting the most appropriate mitigation technique.
