考虑时域稳定性的军事信息系统运维性能评估

An Operation and Maintenance Performance Evaluation in Military Information System in Consideration of Time Stability

军事信息系统在信息时代体系作战中发挥的作用日渐显著,对其运维性能进行综合评估,有助于掌握军事信息系统整体运用情况。针对考虑时域稳定性的系统运维性能评估问题,通过构建“6+20”两级指标体系,建立了考虑时域稳定性的性能评估模型;随后基于综合主客观信息,采用拉格朗日乘子法确定最优指标权重,以方差值为优化目标确定评估时点权重,并在确定指标和评估时点权重基础上进行系统运维性能评估结果的生成;最后通过仿真算例,验证了所提出方法的有效性和可靠性,为军事信息系统运维性能评估提供方法支撑。

Military information systems are playing an increasingly important role in system operations at the information age,and comprehensive evaluation of performance is helpful to grasp the overall situation of system operation and maintenance.In view of the system operation and maintenance performance evaluation problem in consideration of time stability,first,a 6+20 two-level index system is built up.Secondly,a performance evaluation model in consideration of time stability is established.Based on comprehensive subjective and objective information,the optimal index weights are determined by adopting the Lagrange multiplier method,After that,the weight of the evaluation time is determined with the variance value as the optimization goal.And the system operation and maintenance performance evaluation results are generated on the basis of determining index and evaluation time weights.Finally,the proposed method is verified by simulation examples.
