基于作战网络可靠度的体系贡献率评估

System of systems contribution rate evaluation based on operational network reliability

针对武器装备体系中日益复杂的装备种类、交互关系和大量兼具多种功能的综合型武器装备,建立了包含综合型装备的武器装备体系作战环网络描述模型。首先,结合网络可靠度思想对现有的作战环网络能力求解方法进行改进,分别给出了基于不交最小路的精确求解方法和基于谱半径的蒙特卡罗近似求解方法。之后,给出了一种改善的综合型装备体系贡献率评估方法。最后,利用作战实例对上述建模求解流程进行检验,并利用程序生成随机网络对两种算法进行了比较。结果表明,上述评估流程具有良好的可行性和准确性,两种算法对不同规模的网络在运算时间和精度方面则具有不同的适用性。

In view of the increasingly complex equipment types,interaction relations and a large number of multifunctional equipment in the armament system of systems,the operation loop network description model of the armament system of systems containing the multifunctional equipment is established.Firstly,based on the network reliability theory,the method of calculating the armament system of systems operation capabilities is improved,and two methods of the min-path method and the Monte Carlo method based on spectral radius are presented.Then,an improved evaluation method of contribution rate is presented.Finally,an operation system example is used to verify the above modeling and solving process.The two algorithms are compared by using the random network generated by the program.The result shows that the evaluation process is feasible and accurate,and the two algorithms have different applicability to networks of different sizes in terms of calculation time and accuracy.
