The initial ideas for founding SISCOG started to be discussed in 1982 while João Pavão Martins and Ernesto Morgado were Ph.D. students in artificial intelligence at the State University of New York at Buffalo.
SISCOG has implemented its decision support systems in companies like the Canadian Railways, Dutch Railways, Finnish Railways, Norwegian State Railways, Danish State Railways, DSB S-Tog - Copenhagen Suburban Trains, London Underground and Lisbon Metro.
