复杂维修系统的动力学行为仿真

装备维修系统是复杂的动力学系统，其不同构成之间的相互作用导致维修系统的动态变化。从信息的角度看，维修需求的变化是驱动整个系统运作的关键，从而为实现维修系统的有效管理和控制，必须深入理解维修系统变化的内在动力学行为，特别是系统的暂态行为。系统仿真方法为分析暂态行为提供了可能，为此论文考虑了两级维修体制下一类装备的维修系统，分析了其运作过程并由此设计和实现了相应的仿真框架和算法。算例的仿真结果表明了仿真框架和算法的有效性，并揭示了传统随机过程方法所未能展示的维修系统的非线性动力学行为。

Simulations for Dynamic Behaviors of Complex Maintenance System

Equipment maintenance system is naturally a complex dynamical system, in which the cor?relations of its different parts determine the changes of the whole. From the viewpoint of information, the changes of maintenance requirements are the key drivers of the operation of whole system. To?wards the practical management and effective control of maintenance system, it is necessary that the intrinsic dynamic behaviors, especially the transient behaviors of maintenance system, must be cap?tured. So the simulation method was used, and a two level maintenance system for a class of equip?ment was considered. The operation process of the maintenance system was analyzed, and the simula?tion framework and the algorithm were proposed and implemented. The simulation results show the effectiveness of the framework and the algorithm, and reveal the maintenance system’s nonlinear dy?namics, which is never given by traditional random process method.
