摘要:

异构仿真网络是实况、虚拟和构造(live, virtual, and constructive, LVC)仿真的基础环境支撑,合理评估其可靠性在LVC仿真应用中具有重要作用。针对复杂网络可靠性评估难以获得精确解、效率不高的问题,提出一种考虑节点失效的LVC异构仿真网络蒙特卡罗评估方法。首先,基于异构网络自身特点及因子定理,对蜂窝网络和无线传感器网络进行等效转化;其次,运用可靠性保持缩减技术对转化的仿真网络进行缩减,提高算法效率和收敛速度;最后,依据不完全可靠节点转化原则,对简化网络可靠性进行蒙特卡罗模拟,实现LVC异构仿真网络连通可靠性的评估。计算结果表明,相比传统蒙特卡罗方法,所提方法在保证计算精度的同时,方差减小,运行负载较小,稳定性更好。

Abstract:

The heterogeneous simulation network is the basic environment support for the live, virtual, and constructive (LVC) simulation. Reasonable evaluation of its reliability plays an important role in LVC simulation applications. Aiming at the problem in obtaining accurate solutions and poor efficiency for reliability evaluation of complex networks, a Monte Carlo evaluation method of the LVC heterogeneous simulation network considering imperfect vertices is proposed. Firstly, based on the characteristics of the heterogeneous network and the factoring theorem, the equivalent conversion of the cellular network and the wireless sensor network is performed. Secondly, the reliability preserving reduction technology is used to reduce the converted simulation network to improve the algorithm efficiency and convergence speed. Monte Carlo simulation is performed on the simplified equivalent network reliability calculation based on the principles of imperfect vertices conversion. The reliability evaluation of the LVC heterogeneous simulation network connectivity is realized. The calculation results show that, compared with the traditional Monte Carlo method, the proposed method can reduce the variance, decrease the operating load and improve the stability while ensuring the calculation accuracy.

Key words: live, virtual, and constructive (LVC) simulation, heterogeneous simulation network, connecting reliability, imperfect vertice, Monte Carlo
