基于云理论的舰载导航装备效能评估方法

Effectiveness evaluation method of shipborne navigation equipment based on cloud theory

针对基于云重心和云模型的传统效能评估方法的不足,提出一种新的基于云理论的效能评估方法.该方法利用逆向云算法得到指标云模型,基于云模型对确定权重的排序法进行改进,利用云的代数运算得到系统效能的云模型,采用基于黄金分割率的模型驱动确定评估等级,并利用正向云算法显示评估结果.评估算例及结果分析表明,该方法可行有效,既减少了评估中的主观成分,又可得到全面直观的评估结果,为舰载导航装备等复杂系统的效能评估提供了一种新思路.

Aiming at the shortcomings of the traditional effectiveness evaluation methods based on cloud gravity center and cloud model,a new effectiveness evaluation method based on cloud theory was proposed. The index cloud model was set up by the reverse cloud algorithm to improve the ranking method which determine the index weight,the system effectiveness cloud model was set up by the cloud algebraic operations,the evaluation grade of the system effectiveness cloud model was determined by the model- driven method based on the golden section ratio,and the evaluation results were displayed by the forward cloud algorithm. The evaluation example and result analysis show that this method is not only reduces the subjective factors in the evaluation,but also gets overall and visualized evaluation results,which provides a new way for effectiveness evaluation of complex systems in shipborne navigation equipment etc.
