本文基于笔者提出的一种可行的通信网可靠性评价模型,进行了网络性能的敏感性分析,得到了若干有意义的结果。本模型充分考虑了通信系统的动态特性、随机性、模糊性及系统毁坏后的可修复特性。本模型以节点的连通性、平均响应时延及系统的总品质因数作为评价指标,通过敏感性分析,以达到优化通信网络系统的目的。 Based on a feasible model of communication network reliability evaluation proposed by the author, this paper analyzes the sensitivity of network performance and obtains some meaningful results. The model fully considered the dynamic characteristics of communications systems, randomness, fuzziness and repairable features after the system is destroyed. In this model, node connectivity, average response delay and the total quality factor of the system are used as evaluation indicators to achieve the purpose of optimizing communication network system through sensitivity analysis.
