A model for planning regarding college faculty is described. The USC Faculty Planning Model was developed by Robert Linnell and Paul Gray in 1974 at the University of Southern California as an interactive mathematical model to trace characteristics of faculty groups over time. Characteristics listed by the model include: faculty age distribution, number of openings, affirmative action data, number of retirements per year, total and average faculty salaries, and percent of faculty tenured. Faculty planning and modeling is claimed to have three basic advantages over other approaches to policy making: (1) modeling simulates human behavior, (2) modeling is economical in terms of time and money, and (3) modeling permits policies to be tried out so that problems with the policies can be discovered before they would arise via implementation. Advantages and disadvantages of this approach and some examples of its application are considered. Two ways that this computer system planning model can be utilized are explained, and costs are quoted. (SW)
