Computer Simulation Model for Forecasting Mileage Accumulation and Testing Rate 790704

Management of large emissions testing programs can be improved by using simulation models to predict performance and evaluate the effects of operational changes prior to implementation. During the Coordinating Research Council (CRC) methylcyclopentadienyl manganese tricarbonyl (MMT) Field Test Program(1,2)*, a computer model of the mileage accumulation and testing functions of the program was developed and used to establish work schedules, project cost forecasts, and optimal scheduling of activities on individual vehicles. The principles of this model and the methods employed are based on queuing theory and can be applied to any complex vehicle test program.
