摘要
评估战时城市网络目标重要度对拟制目标打击顺序和火力分配方案具有重要的意义。针对现有模型多采用无向无权网络,导致模拟真实世界时存在结果不客观、分析不深入等问题,在定义了一种兼顾局部和全局连接属性的关键节点测度新指标DWNR值的基础上,提出通过有向加权网络模拟战时城市网络目标的方法来进行重要度评估,利用入强度指标初始化网络各节点并进行预估排序,有效地提高了收敛速度和识别精度。仿真结果表明,采用有向加权网络评估战时城市网络目标重要度的方法不仅结果准确有效,而且效率较高,验证了上述评估模型的可行性和有效性。
It is very important to evaluating the city network objective importance on studying out the beating order and firepower admeasure plan. Aiming at the problem that with non - directed weighted network model, the simulation and analysis of real - world is neither objective nor thorough, this paper not only defined a new evaluation metric for vital node importance, which is called Directed Weighted Node Ranks （DWNR） and possesses the local and entire link characteristics, but also designed an importance evaluation model of city objective network by using direct- ed weighted network. Initializing and ranging the nodes of networks by using the index of in - degree, the model can improve the constringency rate and identify precision. According to the simulation example, the feasibility and validi- ty of city objective network＇s importance evaluation by this method are verified, and the results are not only effective and accurate, but also of high efficiency.
