Abstract: The parallel and integrated simulation of human-object interaction is critical for simulation studies on human-object hybrid systems.The issue of human-object interaction of human-object hybrid systems in managerial activities is divided into two aspects including the evolution of the manager's self-efficacy and the processing of tasks.Both qualitative and discrete event simulation approaches are adopted to build two models respectively.The multi-thread technology of Visual Basic.Net and RT Execution mode of Arena are employed to design and develop a prototype of PSMS-SMMPT system based on message passing,thus realizing the parallel and integrated simulation of human-object interaction.Verification and validation of the system show that it is credible for explorations on dynamics of human-object interaction in managerial activities.
