Ferramenta de desenvolvimento e de aplicação de lógica Fuzzy

Abstract

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.
