Beginning January 1, 1969, Systems Research Group (SRG) undertook a project to develop operational cost simulation models of three of the colleges of applied arts and technology in Ontario. These models, and the data needed to feed them, have been developed and are now operating. SRG describes their progress to date and identifies the remaining activities they have undertaken. A computer aided information system has been designed and set up in the colleges. It includes procedures and forms for gathering and preparing the data needed as well as for reporting on the results of a simulation. (TC)
