Colored Petri net as a model of a system for supporting credit decisions

Grzegorz Dec, Bartosz Jędrzec, Wojciech Rząsa


The paper describes a formal model and implementation of an expert system (ES) for a credit decision making. The ES is designed as a set of related decision tables (DT). The Colored Petri Net (CPN) is adopted as a model of the ES. The structure and behavior of the ES is mapped into the CPN. A software module for a credit decision making is developed and deployed to a computer system for banking.
