The man in the loop simulation is applied to the operation plan simulation, can achieve the purpose of thorough analysis problems. From operation plan simulation is introduced into the demand of human intervention, on the basis of introduced operation plan simulation process, analysis of simulation can intervene in the content, respectively in detail, and the content of the different types of intervention program debugging breakpoints in the conceptual design for reference under the different timing of intervention operation mode, describe human intervention after the simulation operation process. Results show that the research can adjust events and event processing parameters in the simulation of the operation plan, and provide the method for the application of human intervention in the operation plan simulation.
