Harvesting systems have in many cases become so large, and the machines often so complex, that mistakes in the design of such systems may become very expensive. It may become impossible for one man to keep track of each system element and it's interrelationships with other elements to the extent necessary to predict the results of subtle changes in system design. Simulation of the system by digital computer provides a working model with which to experiment and plan. Programming languages provide the communication between man and computer for such work.
