SADF: sistema de análise de diagramas de fluxo.

Abstract

SADF - System of Analysis of Flow-Graph - is a tool designed to serve as an aid in determining the algebraic relation amongst the variables of a linear system. This is based on analysis of the signal flow diagram and application of the Mason's rule and the superposition theorem to relate any of the system variables with the independent excitation sources present in the system. SADF has been written in the programming language PASCAL, for IBM-compatible personal computers. SADF is easy to use due to its user-friendly interface, provides on-screen help with a view to augment the overall performance of the system. SADF has other built-in resources and flexibility to adapt it to the type of problem at hand or the desired response. This flexibility permits that this tool may be employed in other fields to resolve problems that involve the analysis of flow or the topology of sets. I
