This paper presents the idea of a proposed Manufacturing Foundation Ontology (MFO) aimed at acting as a basis for the Product Life Cycle (PLC) interoperability. MFO is aimed to have the provision for introducing interoperability not only across departments but across organization as well. The proposed idea shows the development of a MFO in several layers and various levels in those layers. The foundation ontology will act as a basis for building Interoperable knowledge bases or ‘World Models’ from a library of formally defined concepts in a heavy weight ontology. MFO must be flexible enough to allow organizations to be able to model their own domains with the flexibility to use the terms they want. Rules and axioms governing each and every concept add rigour to the semantics of the MFO and restrict the use of concepts to facilitate interoperability with a minimum effect on flexibility to model.

This paper proposes a manufacturing core concepts ontology (MCCO) aimed at providing support for product life cycle interoperability. The potential focus of the work is interoperability across the production and design domains of product lifecycle. A core set of manufacturing concepts and their key relationships are identified in MCCO. Semantics are captured formally through heavyweight logic using rigorous rules and axioms.

Information flows and products traceability are considered as tools to protect consumer safety. To meet traceability requirements, it is mandatory to find a system able to trace all relevant information related to the product lifecycle. This information is quite often scattered within organizations. The heterogeneity of applications induces a sort of “Babel tower effect”, which causes traceability problems, leading systems to fail at collecting information from different and heterogeneous sources to effectively trace the product lifecycle. Generally speaking, this kind of problem falls within the umbrella of interoperability problems. This paper postulates a different point of view to resolve these problems, the product-driven point of view, starting from the observation that the product is the common element perceived in all manufacturing operations and that added values are engraved on it unequivocally. The paper extends previous research activities by sketching a common informati...

Nossa hipótese é a de que o exame das marcas de enunciação que se depositam em versões de texto ajuda a reconstruir um percurso de pesquisa e as transformações pelas quais um pesquisador passa ao longo de sua formação. A pesquisa monstrou o trabalho invisível do orientador que ajuda na conquista do espírito científico (BACHELARD, 1996). O corpus foi composto por 1101 versões das dissertações de mestrado de quatro informantes. Quando necessário, foi instruído pela correspondência eletrônica relacionada à devolutiva das versões. Nos aspectos relativos à relação do pesquisador com o saber, o orientador incide sobre os seguintes comportamentos: inibição; isolamento; apatia; administração do tempo; desordem; inconsequência, colagem a terceiros e delegação de responsabilidade. Nos aspectos relativos à elaboração intelectual, evita que o aluno tome o secundário pelo essencial; os textos lidos como verdades absolutas; selecione elementos aleatoriamente; permaneça fechado e não consiga descr...
