In addition, the output of the operation model building module 30 is connected to the input of the database storage module 70. When the method is specifically used, in the process of establishing the product operation model, because the operation model information stored by the database storage module 70 is limited, all model calls of each product cannot be satisfied, at this time, the operation model establishment module 30 is required to virtually establish the operation model, the established operation model information is transmitted to the operation model establishment module 30, and the operation model establishment module 30 is further supplemented with the operation model, so that the adaptation effect of the operation model establishment module 30 is improved.
In addition, the input end of the database storage module 70 is connected with the output end of the operation result simulation module 60. When the training system is specifically used, the operation result simulation module 60 outputs operation results of the trainers, and transmits operation result information of each trainer to the database storage module 70, and the database storage module 70 records the result of each training of each trainer for later qualified training treatment.
