A probabilistic model that could be used to evaluate the product characteristics of an aggregate processing plant was developed by combining several theories and mathematical models. The model interest was confined to crushing and screening subsystems. The final model is in the form of a computer programming model that is ready for application to similar plant systems. The computer model will store and compile a series of subroutines; each subroutine performs a specific function, and the whole model analysis procedure is controlled by a main program. A simulator is used to generate desired data to provide for the evaluation of the statistical nature of the output products. Through the use of the high-speed computer, parameters of plant production control--such as raw material feed rate, crusher settings, screen mesh sizes, combining and splitting of certain production flow streams, and appropriate production demand schedules--can be easily evaluated. By varying the data on raw feed material, the model evaluates the tonnage and gradation of the flow streams in the production plant as well as variability. The program analyses used in the proposed model are logical and compatible with those used in the aggregate production industry. Extensive experimental data are still required to ensure the validity of the model. /Authors/
