Ostensibly, the generation of time histories of these state variables requires continuous simulation, and most belt simulation packages execute what is essentially a continuous simulation using various discretization approaches. However, since it is reasonable to assume that the derivatives of these continuous variables change at discrete points in time, one alternatively can model the system using a higher-order discrete approach. Such an approach is developed in this paper. Advantages offered by the new framework include (1) improved accuracy, (2) faster execution, (3) the ability to realistically interface with models of production or loadout operations, and (4) the ability to study the performance of a wide array of real-time control systems. The framework has been implemented using the event-scheduling interface to the SIMAN simulation language, but it could readily be employed with other discrete-event simulation languages. The framework is demonstrated in examples involving an integrated track/belt haulage system and a system for reduction of peak loads on gathering belts that involves real-time control of feeder discharge rates.
