Reconstruction of function block logic using metaheuristic algorithm: Initial explorations

This paper presents an approach for automatic reconstruction of automation logic from execution scenarios using a metaheuristic algorithm. The IEC 61499 basic function blocks is chosen as implementation language and reconstruction of Execution Control Charts for basic function blocks is addressed. The synthesis method is based on a metaheuristic algorithm most closely related to ant colony optimization and evolutionary computation. Execution scenarios can be recorded from testing legacy software solutions. At this stage results are only limited to generation of basic function blocks having only Boolean input/output variables.
