Smart Agents in Industrial Cyber–Physical Systems

Paulo Leitao, Stamatis Karnouskos, Luis Ribeiro, Jay Lee, more

Proceedings of the IEEE > 2016 > 104 > 5 > 1086 - 1101

Future industrial systems can be realized using the cyber–physical systems (CPSs) that advocate the coexistence of cyber and physical counterparts in a network structure to perform the system’s functions in a collaborative manner. Multiagent systems share common ground with CPSs and can empower them with a multitude of capabilities in their efforts to achieve complexity management, decentralization,...

A temporal agent based approach for testing open distributed systems

Salma Azzouzi, Mohammed Benattou, My El Hassan Charaf, S. Azzouzi, more

Computer Standards & Interfaces > 2015 > 40 > Complete > 23-33

The development of distributed testing frameworks is more complex, where the implementation process must consider the mechanisms and functions required to support interaction as long as the communication and the coordination between distributed testing components. The typical reactions of such systems are the generation of errors‘set: time outs, locks, observability, controllability and synchronization...

Modeling and verifying probabilistic Multi-Agent Systems using knowledge and social commitments

Khalid Sultan, Jamal Bentahar, Wei Wan, Faisal Al-Saqqar, more

Expert Systems With Applications > 2014 > 41 > 14 > 6291-6304

Multi-Agent Systems (MASs) have long been modeled through knowledge and social commitments independently. In this paper, we present a new method that merges the two concepts to model and verify MASs in the presence of uncertainty. To express knowledge and social commitments simultaneously in uncertain settings, we define a new multi-modal logic called Probabilistic Computation Tree Logic of Knowledge...

ABAMA: An Agent-based Architecture for Mapping Natural Ecosystems onto Wireless Sensor Networks

Nafaâ Jabeur, Nabil Sahli, Sherali Zeadally, N. Jabeur, more

Procedia Computer Science > 2014 > 34 > Complete > 257-265

Wireless Sensor Networks (WSNs) comprise of hundreds of spatially distributed sensors which may collaborate, compete, and self-organize in order to solve complex tasks which are beyond their individual capabilities. The efficiency of these actions is commonly restricted by the limited energy, the environmental context, and the processing capabilities of the sensors. To overcome these constraints,...

Combined model checking for temporal, probabilistic, and real-time logics

Savas Konur, Michael Fisher, Sven Schewe, S. Konur, more

Theoretical Computer Science > 2013 > 503 > Complete > 61-88

Model checking is a well-established technique for the formal verification of concurrent and distributed systems. In recent years, model checking has been extended and adapted for multi-agent systems, primarily to enable the formal analysis of belief–desire–intention systems. While this has been successful, there is a need for more complex logical frameworks in order to verify realistic multi-agent...

On applications of quasi-Abelian Cayley graphs to Denial-of-Service protection

Ewa Girejko, Agnieszka B. Malinowska

Bulletin of the Polish Academy of Sciences. Technical Sciences > 2024 > Vol. 72, nr 3 > art. no. e149232

This paper addresses the problem of designing secure control for networked multi-agent systems (MASs) under Denial-of-Service (DoS) attacks. We propose a constructive design method based on the interaction topology. The MAS with a non-attack communication topology, modelled by quasi-Abelian Cayley graphs subject to DoS attacks, can be represented as a switched system. Using switching theory, we provide...

Viktor Mashkov, Andrzej Smolarz, Volodymyr Lytvynenko

International Journal of Electronics and Telecommunications > 2023 > Vol. 69, No. 4 > 713--718

The paper deals with alliances and coalitions that can be formed by agents or entities. It is assumed that alliance agents cooperate and form coalitions for performing the tasks or missions. It is considered that alliance agents are unselfish. That is, they are more interested in achieving the common goal(s) than in getting personal benefits. In the paper, the concept of fuzzy alliance was introduced...

Concept of separation method between aircraft in the transition period

Daria Żuchowska, Anna Stelmach

Prace Naukowe Politechniki Warszawskiej. Transport > 2022 > z. 135 > 5--16

The current concept of air traffic control based on human work was created many years ago and is now approaching the limit of its performance. Therefore, new concepts for air traffic control are being sought. One of the ideas is to delegate the responsibility for ensuring separation between aircraft to aircraft crews. The issue of self-separation is quite a difficult task. Analysis of the literature...

An Intelligent Method for the Scheduling of Cyber Physical Production Systems

Hassan Khadiri, Souhail Sekkat, Brahim Herrou

Management and Production Engineering Review > 2022 > Vol. 13, No. 1 > 44--51

The new industrial era, industry 4.0, leans on Cyber Physical Systems CPS. It is an emergent approach of Production System design that consists of the intimate integration between physical processes and information computation and communication systems. The CPSs redefine the decision-making process in shop floor level to reach an intelligent shop floor control. The scheduling is one of the most important...

An Agent-based Cyber-Physical Production System using Lego Technology

Metehan Mustafa Yalcin, Burak Karaduman, Geylani Kardas, Moharram Challenger

Annals of Computer Science and Information Systems > 2021 > Vol. 25 > 521--531

To cope with the challenges of constructing Cyber-physical Production Systems (CPPS), many studies propose benefiting from agent systems. However, industrial processes should be mostly emulated while agent-based solutions are integrating with CPPS since it is not always possible to apply cyber-based solutions to these systems directly. The target system can be miniaturised while sustaining its functionality...

Evacuation by leader-follower model with bounded confidence and predictive mechanisms

Ricardo Almeida, Ewa Girejko, Luis Machado, Agnieszka B. Malinowska, more

Archives of Control Sciences > 2021 > Vol. 31, No. 3 > 629--644

This paper studies an evacuation problem described by a leader-follower model with bounded confidence under predictive mechanisms. We design a control strategy in such a way that agents are guided by a leader, which follows the evacuation path. The proposed evacuation algorithm is based on Model Predictive Control (MPC) that uses the current and the past information of the system to predict future...

Multi agent deep learning with cooperative communication

David Simões, Nuno Lau, Luís Paulo Reis

Journal of Artificial Intelligence and Soft Computing Research > 2020 > Vol. 10, No. 3 > 189--207

We consider the problem of multi agents cooperating in a partially-observable environment. Agents must learn to coordinate and share relevant information to solve the tasks successfully. This article describes Asynchronous Advantage Actor-Critic with Communication (A3C2), an end-to-end differentiable approach where agents learn policies and communication protocols simultaneously. A3C2 uses a centralized...

The Dynamic Epistemic Logic for Actual Knowledge

Arkadiusz Wójcik

Bulletin of the Section of Logic > 2020 > 49 > 1

The dynamic epistemic logic for actual knowledge models the phenomenon of actual knowledge change when new information is received. In contrast to the systems of dynamic epistemic logic which have been discussed in the past literature, our system is not burdened with the problem of logical omniscience, that is, an idealized assumption that the agent explicitly knows all classical tautologies and all...
