When stakeholders are geographically distributed communication presents new challenges for software engineering community. In order to improve communication between stakeholders, we have previously proposed to apply lear...

The knowledge imperfections should be considered when modeling complex problems. A solution is to develop a model that reduces the complexity and another option is to represent the imperfections: uncertainty, vagueness a...

Self-optimizing mechatronic systems react autonomously and flexibly to changing conditions. They are capable of learning and optimize their behavior throughout their life cycle. The paradigm of self-optimization is origi...

In this work we will study the problem of the design of the "Integration Model for Distributed Database System". We particularly design the canonical model through the ontological handling of the information. The ontolog...

Most component-based approaches to elaborate software require complete and consistent descriptions of components, but in practical settings components information is incomplete, imprecise and changing, and requirements m...

In omplete information is a problem in many aspe ts of a tual environments. Further- more, in many s enarios the knowledge is not represented in a risp way. It is ommon to nd fuzzy on epts or problems with some level of...

O artigo tem como proposta aplicar os conceitos de extração de dados para aumentar o conhecimento sobre o custo do processo produtivo de Empresas Virtuais. Esta abordagem usa técnicas de IA, especialmente lógica fuzz...

En este trabajo se presenta una herramienta desarrollada a través de la integración del lenguaje FCL (Fuzzy Control Language, definido de acuerdo al estándar fijado en IEC 61131-7 CD1) [FCL97] y la biblioteca FFLL (Fr...
