Geração de esqueletos para sistemas de ETL a partir de redes de Petri colorida

As Redes de Petri Coloridas são uma linguagem gráfica com uma semântica bem definida, que permite o desenho, especificação, simulação e validação de sistemas, cujos processos a modelar exijam características específicas de comunicação, concorrência e sincronização entre si. A nível aplicacional, as Redes de Petri Coloridas surgem em áreas muito diferentes, tais como a especificação de protocolos de comunicação, sistemas de controlo, sistemas de hardware ou de sistemas de software. Devido às suas características as Redes de Petri Coloridas foram adotadas, também, na modelação de sistemas de ETL (Extract-Transformation-Load). Meta-tarefas como Change Data Capture ou Surrogate Key Pipelining, frequentemente encontradas em sistemas de ETL convencionais, foram modeladas e validadas através do uso de redes de Petri Coloridas. Tal sustenta, de forma bastante efetiva, o objetivo principal deste trabalho de dissertação: desenvolver e implementar um sistema para a geração de esqueletos para sistemas de ETL a partir da correspondente Rede de Petri Colorida.Coloured Petri Nets are a graphical language with a well-formed semantic, that allows the design, specification, simulation, and validation of systems, which specific characteristics such as, communication, concurrency and synchronization have a main role in the processes to model. At application level, Coloured Petri Nets are used in a wide variety of scientific areas, such as communication protocol, control systems, hardware systems or software systems. Due their characteristics Coloured Petri Nets were also adopted in modeling ETL (Extract-TransformationLoad) systems. Meta-tasks like Change Data Capture or Surrogate Key Pipelining, that are frequently founded in conventional ETL system, were modeling and validated using Coloured Petri Nets. All this support, quite effectively, the main propose of this dissertation work: develop and implement a system to generating skeletons to ETL systems from the corresponding Coloured Petri Nets

Towards the formal verification of human-agent-robot teamwork

The formal analysis of computational processes is by now a well-established field. However, in practical scenarios, the problem of how we can formally verify interactions with humans still remains. This thesis is concerned with addressing this problem through the use of the Brahms language. Our overall goal is to provide formal verification techniques for human-agent teamwork, particularly astronaut-robot teamwork on future space missions and human-robot interactions in health-care scenarios modelled in Brahms
