Dashboard services for pragmatics-based interoperability in cloud and ubiquitou...
Ferreira, Luís; Putnik, Goran D.; Cruz-Cunha, Maria Manuela; Putnik, Zlata; Castro, HélioThe real Cloud and Ubiquitous Manufacturing systems require effectiveness and permanent availability of resources, their capacity and scalability. One of the most important problems for applications management over cloud based platforms, which are expected to support efficient scalability and resources coordination following SaaS implementation model, is their interoperability. Even application dashboards need...
A taxonomy for virtual enterprises
Putnik, Goran D.; Cruz-Cunha, Maria ManuelaThe purpose of this paper is to present a taxonomy able to contribute to building a framework within the domain of Virtual Enterprises (VE), to facilitate the sharing of knowledge and contributions to knowledge, as well as for trust building among VE stakeholders. A VE taxonomy currently does not exist, and this lack is felt in the ambiguous way that some concepts are addressed, leading to a fragment understand...
Formal description technique SDL for manufacturing systems specification and de...
Sousa, Rui M.; Putnik, Goran D.This paper addresses the formal specification and description of manufacturing systems. It is considered the use of SDL (Specification and Description Language), a standard FDT (Formal Description Technique), to model the behaviour, data and structure aspects of a manufacturing system. SDL was originally developed for telecommunication systems (protocol specification and data processing). The adequacy of FDTs, ...
Using formal description technique ESTELLE for manufacturing systems specificat...
Sousa, Rui M.; Putnik, Goran D.; Moreira, FranciscoUsually the description of a system is given in natural language or in diagrams. It is very hard to make this kind of informal description clear, concise and unambiguous. Implementations based on informal specifications are usually prone to errors, omissions and incompatibilities. This paper presents an attempt to introduce Formal Description Techniques (FDT's), originally developed for the area of telecommunic...
Man-Machine interface for remote programming and control of NC machine-tools at...
Moreira, Francisco; Putnik, Goran D.; Sousa, Rui M.This paper presents an example of Man-Machine Interface for remote programming and control of NC machine tools. The system is based on a computer virtual panel which substitutes the machine control panel and in telematics interfaces which establishes the basis for geographical independence between the physical equipment and human operator.
Distributed/virtual manufacturing system cell : an experimental installation
Putnik, Goran D.; Sousa, Rui M.; Moreira, Francisco; Spasic, Z.; Babic, B.; Carvalho, DinisThe main objectives of the “Distributed/Virtual Manufacturing System (D/V MS) Cell” project are: (1) The development of Tele-services technologies and organisation for the production planning and control functions; (2) The development of permanent high performance laboratory facilities that enable development and demonstration of D/V MS design and control, i.e., global distribution of production planning and co...
