The basis of the System of Mass Control (SMC) simulation model is to generate time requirements, monitor the status of operator stations, generate operator times, and register simulated duty cycle data for the requirements to calculate SMC efficiency criteria. The first part of the article consists of general information about the problem. Next parts are focused on highlighting the basis of numerical simulation of the SMC, pattern of constructing the simulation model of the SMC and the animation of its functionality. The fifth part consists of an example of a utilization of the model for an optimization of the parameters of aircraft ground handling. According to the simulation, results offer solutions for the simulated model of SMC. From the given values of input parameters applied by the simulation models, we achieved information about attained values of single criteria for a specified option of the aircraft handling system.
