Com o objetivo de estruturar conhecimento envolvido no contexto de processos industriais, esta tese prop?e uma ontologia de dom?nio, denominada OntoAut, que modela conceitualmente dos elementos envolvidos na descri??o de porcessos industriais. Para validar a ontologia proposta s?o apresentados diversas aplica??es. Na primeira, s?o modelados conceitualmente dois processos t?piocs: tratamento DEA (Dietanolamina) e forno industrial. Na segunda aplica??o, utiliza-se a ontologia para realizar uma filtragem sem?ntica de de alarmes, que aliada a analises de correla??es, determina rela??es temporais entre alarmes de um processo industrial. Na terceira aplica??o, utiliza-se a ontologia para modelagem e an?lise de custo de constru??o e opera??o de processos. Na quarta aplica??o, a ontologia ? adotada para para analisar a confiabilidade de uma planta industrial. / The main hypothesis of this thesis is that the deve lopment of industrial automation applications efficiently, you need a good structuri ng of data to be handled. Then, with the aim of structuring knowledge involved in the contex t of industrial processes, this thesis proposes an ontology called OntoAuto that conceptua lly models the elements involved in the description of industrial processes. To validat e the proposed ontology, several applica- tions are presented. In the first, two typical indu strial processes are modeled conceptually: treatment unit DEA (Diethanolamine) and kiln. In th e second application, the ontology is used to perform a semantic filtering alarms, which together with the analysis of correla- tions, provides temporal relationships between alar ms from an industrial process. In the third application, the ontology was used for modeli ng and analysis of construction cost and operation processes. In the fourth application, the ontology is adopted to analyze the reliability and availability of an industrial plant . Both for the application as it involves costs for the area of reliability, it was necessary to create new ontologies, and OntoE- con OntoConf, respectivamentem, importing the knowl edge represented in OntoAuto but adding specific information. The main conclusions of the thesis has been that on tology approaches are well suited for structuring the knowledge of industrial process es and based on them, you can develop various advanced applications in industrial automat ion.
