Abstract. Service-oriented Multi-Agent Systems (SoMAS) is an approach to combine the fundamental characteristics of service-oriented and multi-agent methods into a new platform for industrial automation. Several research works already targeted the connection of these technologies, presenting different perspectives in how and why to join them. This research focuses on available efforts and solutions in the area of SoMAS and explains the idea behind the service-oriented agents in industrial automation. A SoMAS system is mainly composed by shared resources in form of services and their providing/requesting agents. The paper also discusses the required engineering aspects of these systems, from the internal anatomy to the interaction patterns. Parameters of flexibility, reconfiguration, autonomy and reduced development efforts were considered and they should be the trademark of SoMAS. Aiming to illustrate the proposed approach, an example of service-oriented automation agents is given.

“…For short, Service Infrastructure has the necessary functions to provide service capabilities; Device Interface permits to access the hosting device (if the application runs on one), mainly for reading and setting I/O signals; Graphical User Interface (GUI) can be used for visual representations and also communication to the user; Decision Support System (DSS) is used for conflict resolution and exception handling. For more info about this modular architecture see [15]. Besides the formal structures/rules and analysis capabilities provided by Petri nets, the real "juice" of the controller is the ability to interpret Petri nets models and their association to services and device signals.…”

-In industrial automation, service-orientation is a relatively new and ascending concept and thus, concrete integrated methodologies are missing to accomplish the required development tasks. A suitable approach is to use the powerful set of features that Petri nets formalism provides for such dynamic systems. This paper presents a token game template that is part of the open methodology for the development of customized Petri nets controllers, targeting the engineering of service-oriented industrial automation. This template is based on a state machine specification for the life-cycle of transitions that leaves several options open for extending it with features depending on the application. The practical use and implementation should bring, among others, featured-full and integrated modeling, analysis and control capabilities, which is required by service-oriented ecosystems. This core structure was used and validated in the development of control applications for an industrial automation system.

“…The proposed architecture for reconfigurable automation systems is based in Service-oriented Architecture (SoA) principles, which introduces distributed control structures that exhibits agility, modularity and interoperability [5]. The achieved reconfigurable automation systems are based on modular and simple mechatronic devices, each one providing a set of services that represent its internal functionalities.…”

Abstract-Service-oriented systems constitute a suitable approach for the development of modular, flexible and reconfigurable production systems, addressing the current requirements imposed by global markets. This paper focuses on the process control of Service-oriented production systems, whose behavior is regulated by the coordination of services that are available from distributed modular and collaborative control components. The proposed control is based on a kind of Highlevel Petri Nets tailored for the description, connection and synchronization of different concurrent processes. Several features can be distinguished by this approach, since its modularity, control reusability, flexibility and other valuable inherited characteristics from the proposed High-Level Petri Nets.
