Stanislaw Raczynski received his master degree (1964) from the Academy of Mining and Metallurgy (AGH) in Krakow Poland, Electrical Engineering Department, his Ph.D. (1969) and Habilitation degree (1977) from the same Academy, in the area of control theory and optimization methods. In 1964 Dr.Raczynski joined the Institute for Automatics and Industrial Electronics of the AGH. From 1971 through 1972, he was head of the Computer Center of the AGH. Between 1973 and 1976 he worked as a researcher in the International Research Group in Moscow, USSR. In 1976 Dr.Raczynski became head of the Systems Analysis Group at the AGH. From 1980 through 1983 he participated in the activities of the European Workshop on Industrial Computer Systems. Between 1983 and 1986 he was a visiting professor of the National University of Mexico. In 1986 Dr.Raczynski joined the Panamericana University in Mexico City.Between 1996 and 2000 and then between 2002 and 2004 Dr. Raczynski has been the International Director of The Society for Computer Simulation. He wrote several books on computer simulation (Wiley, UK and LIMUSA, Mexico, Springer) and has more than 140 articles and papers published in professional journals and conference proceedings.
