Several models of operator behaviour for simulating human controlling and decision—making processes in man—machine system were introduced. The first one was an optimal control model (OCM) which has been used for simulating human controlling processes in tracing systems, the second one was a fuzzy control model (FCM) which has been presented for analysing human decision—making processes in antiaircraft gun system. These models are all effective in man—machine system theory and its applications. A new model was presented in the context of an architecture for simulating human controlling and decision—making processes. In such a model the decision—making processes leading to decisions as well as the realization of control were simulated in details for the study of the vehicle control system. The model consists of three levels, namely, the High Level Decision Making (HLDM), the Low Level Decision Making (LLDM), and the Direct Level Controlling (DLC). Details of formalisms and methodologies implemented in the models were described and possible applications in the field of complex man—machine system were discussed.
