Petri net based engineering and software methodology for service-oriented indus...
Mendes, João M.; Restivo, Francisco; Leitão, Paulo; Colombo, Armando W.Indexado ISI ; Collaborative industrial systems are becoming an emergent paradigm towards flexibility. One promising solution are service-oriented industrial automation systems, but integrated software methodologies and major frameworks for the engineering are still missing. This paper presents na overview of the current results on a unified and integrated methodology based on intrinsic and novel features of P...
Energy aware knowledge extraction from Petri nets supporting decision-making in...
Leitão, Paulo; Alves, Joel; Mendes, João M.; Colombo, Armando W.This paper introduces an approach to decision support systems in service-oriented automation control systems, which considers the knowledge extracted from the Petri nets models used to describe and execute the process behavior. Such solution optimizes the decision-making taking into account multi-criteria, namely productive parameters and also energy parameters. In fact, being manufacturing processes typically ...
Composition of Petri nets models in service-oriented industrial automation
Mendes, João M.; Leitão, Paulo; Restivo, Francisco; Colombo, Armando W.In service-oriented systems, composition of services is required to build new, distributed and more complex services, based on the logic behavior of individual ones. This paper discusses the formal composition of Petri nets models used for the process description and control in service-oriented automation systems. The proposed approach considers two forms for the composition of services, notably the offline com...
Process optimization of service-oriented automation devices based on Petri nets
Mendes, João M.; Leitão, Paulo; Restivo, Francisco; Colombo, Armando W.Best paper award. ; This paper introduces a novel method for the specification and selection of criteria-weighted operation modes for the orchestration of services in industrial automation using Petri nets. The objective is to provide to the internal decision support system of a service-oriented automation device or of another applicable computational system the capability to select the best path in a Petri ne...
Software methodologies for the engineering of service-oriented industrial autom...
Mendes, João M.; Bepperling, Axel; Pinto, João; Leitão, Paulo; Restivo, Francisco; Colombo, Armando W.Indexado Inspec ; Service-orientation represents a new wave of features and solutions by bringing closer Information Technology to the industrial domain, particularly factory shop floors. The service-oriented automation software entities (designated here by bots) used in such approach requires a short set of methodologies and software targeting their specification for both computer systems and embedded automat...
Customizable service-oriented Petri net controllers
Mendes, João M.; Restivo, Francisco; Leitão, Paulo; Colombo, Armando W.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 cu...
Specifications of a device interface for service-oriented automation control co...
Barbosa, José; Mendes, João M.; Leitão, PauloService-oriented paradigm is being used to develop distributed and reconfigurable control solutions for factory automation environments. Since service-oriented automation control components are logical entities that provide and consume services, they may have an interface that maps the logical processes into the actions of the representative physical mechatronics. The inter-connection with the physical hardware...
Router-scheduler for the modular anatomy of service-oriented automation components
Mendes, João M.; Sousa, José; Leitão, Paulo; Colombo, Armando W.; Restivo, FranciscoAutomation and production systems are evolving in the direction of autonomous and collaborative components, approaching the idea of an ecosystem. A single habitant of this system is responsible for different and concurrent activities and thus it requires a special adapted anatomy that is balanced for the several requirements. This work introduces an anatomical-like structure for the development of functional an...
Service-oriented control architecture for reconfigurable production systems
Mendes, João M.; Leitão, Paulo; Colombo, Armando W.; Restivo, FranciscoEvolvable and collaborative production systems are becoming an emergent paradigm towards flexibility and automatic re-configurability. The reconfiguration of those systems requires the existence of distributed and modular control components that interact in order to accomplish control activities. This paper focuses on service-oriented production systems, which behavior is regulated by the coordination of servic...
Service-oriented process control using high-level petri nets
Mendes, João M.; Leitão, Paulo; Colombo, Armando W.; Restivo, FranciscoService-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 com...
