Abstract

A GPSS simulation model was developed to investigate the behavior of a university's motor pool dispatch fleet. Data were collected and frequency distributions were constructed for request rates and trip duration times. Regression analysis was performed to formulate mileage generator(s) as a function of service time. Statistical tests were conducted to assess degree of congruence between actual system behavior and theoretical expectations. Analysis of simulated response variables indicates that the model's internal configuration reflects reality to a high degree. Results of fifteen years of simulated experience seem to suggest that reductions in fleet capacity could be effected without undue impairment of service levels.
