Charles Forgy

Production Systems Technologies

Charles is the CTO of Production Systems Technologies and a Strategic Advisor to Sparkling Logic. Charles has been involved with rule engines for decades. In the mid 1970’s he developed the Rete algorithm while a Ph. D. candidate at Carnegie-Mellon University. After graduating in 1979, he remained at Carnegie-Mellon on the research faculty, where he was co-principal investigator of a DARPA-funded project to develop special hardware for rule engines. In 1983, he co-founded Production Systems Technologies (PST) to continue research and development of rule engine technology. The primary business of PST is to customize and license rule engines for embedding in large systems. At PST he developed the more efficient Rete-II and Rete-NT versions of the Rete algorithm, as well as a parallel rule engine for handling high volume and high velocity data. Charles met his future wife, Diana, while at Carnegie-Mellon. Charles and Diana still live in Pittsburgh, PA. They have three children and two grandchildren.
