基于粗糙集的雷达模拟机培训质量综合评价研究
|
摘要
为了提高雷达管制模拟机培训质量评价的准确性和有效性,减少评判者的主观差异对评判结果的影响,提出了一种基于粗糙集理论的综合评价方法。建立了科学的雷达管制模拟机培训质量综合评价指标体系及信息系统;使用基于Pawlak属性重要度的属性约简算法约简信息系统,简化了评价指标体系;采用基于属性重要度的方法确定指标权重,保证了评价的客观性。结果表明,提出的评价方法可减少管制教员的主观影响,能真实反映雷达管制学员的水平,对于提高雷达管制培训质量有着重要意义。
In order to improve precision and availability of radar simulator training achievements assessment and reduce the effects of evaluators' subjectivity diversities on evaluation results, an assessment method based on rough set theory is proposed. With this method, the index system of radar simulator training achievements assessment is set up and the information system based on rough set theory is built; unnecessary attributes are eliminated by using the heuristic reduction algorithm based on Pawlak attribute importance degree, and the index system is simplified; weights of evaluation indeices are determined based on the importance degree index information.Evaluation result shows that evaluation cost and evaluators' influence on evaluation results can be reduced by using the proposed method in radar simulator training achievements assessment.
