Resumo:
Fuzzy logic has been used to make activities which comprise ambiguous situations
totally automatic, treating the problems under a new paradigm. Its potentiality lies in the
capacity of drawing conclusions and getting answers based on vague, on ambiguous
parameters. It brings the computerized decision close to the human decision, making the
machines more capable to perform their tasks. It can be used to make activities of
industrial, biological or chemical nature more automatic.
Even though the mathematics involved in the development of this logic is known in
the available literature, a different form of representing it will be presented. The analysis
and project will be outlined, based on objects of a Fuzzy logic development tool.
The application developed throughout this work made use of a distributed systems
platform, covering its use. The language used is a .Net Framework compliant. The system
works as a DLL (Dynamic Link Library) component which, just like a function, can be
used by any application, provided the calls to the component are included in the
application code.
As an advantage, the tool developed presents graphical resources for configuration of
the Fuzzy logic, simulation of results, input and output of data through any Excel
spreadsheet and, the most important, methods open to the user. With this last functionality,
it is possible to interrupt the system at any stage of processing, so new solutions can be
changed or implemented. This way, the system can be used to help any fuzzy applications
making it a powerful tool to help and develop computer solutions for use under uncertainty
situations and for process control.
