Effectively integrated the mine physical natural environment information into the mine virtual environment, the MSNE model can enrich enormously the virtual environment knowledge and enhance its practicabilityThirdly, the modeling method of virtual human in MIVE was studied systematically and an intelligent virtual miner model was constructed. The intelligent miner has lifelike human appearance and possesses abroad ability of perception, motion, behavior, cognition and mental state. And a behavior control model based on the simpled consumption architecture was proposed to select, activate and terminate the basic reactive behavior for virtual miner. And some intelligent behaviors including vision perception, path planning and self-determining ramble also were studied. The intelligence and interaction of virtual environment are just embodied by the intelligent life, especially by the intelligent behaviors of virtual human.

Furthermore, this model is expanded in two aspects: on the one hand, through the introduction of the theory of the Fault Tree, this thesis analyzes the difference between the fault-diagnosis in the recovering flow and that in the traditional flow, thus concluding that the fault-diagnosis in the recovering flow is just a tracing-back process of the directed-graph and the Fault Tree; on the other hand, a finite self-restoring state machine is constructed on the directed-graph model, thus providing the theoretical basis for the realization of the auto-recovery model.

随后在两个方面对该模型进行了扩展：1。通过引入故障树的方法，并在分析了恢复流程故障诊断与传统故障诊断的差异之后，总结出恢复流程的故障诊断就是一个基于有向图和故障树进行回溯的过程；2。基于有向图模型建立了一个有穷自动状态机，为自动恢复与模型的实现提供了理论基础。

After introducing the AOP, there are components, system connectors, aspect connectors and constraints in architecture.
