A computer-based simulation model is described that can be used in an interactive mode to analyze the effects of alternative hiring, promotion, tenure granting, retirement, and salary policies on faculty size, distribution, and aggregate salary expense. The model was designed to be adequately flexible and comprehensive to incorporate the array of faculty appointment and tenure types found in medical schools throughout the United States. It has been implemented and tested on historical faculty data from the Case Western Reserve University School of Medicine. The Monte Carlo method of simulation was chosen as the most effective technology. The present model is called the "Tenure and Promotion Policy Simulator" and is programmed in the BASIC language. The entry, promotion, tenure status, and departure of full-time faculty members of the School of Medicine was traced from 1944-45 through 1977-78, totaling over 1,850 individuals. A computer data file was then constructed containing encoded biographical and appointment history information. Six data aggregation and synthesis computer programs were written to display the data in forms appropriate for analysis of the interrelationships of each variable on others. Statistical tests were run to determine the independent variables that have a significant relationship with the probability of a faculty member receiving a promotion, tenure, and other actions. Validation of the model was also undertaken. (SW)
