中文摘要: 针对GEO卫星频轨选取风险评估面临的参评指标因基础数据条件不同而参差不齐、指标赋权因用户经验不同而存在差异的问题,提出了一种GEO卫星频轨选取风险的柔性评估方法.在模糊综合评估法的基础上,从指标计算映射、指标权重配置两个方面支持用户的柔性化配置.针对用户在指标计算映射和指标权重配置方面的差异化,分别提出了基于聚类分析和正态分布模型自主学习的柔性构建方法,融合用户的经验知识,形成大多数用户认可的指标计算映射关系和指标权重配置,使风险评估更加科学化、合理化.基于该柔性的风险评估方法,开发了B/S架构的柔性评估系统,并通过实例验证了算法和系统的有效性.
Abstract:Aiming at the problem that the index is different due to basic data conditions and the index weight is different due to diversity of user experience in GEO satellite frequency and orbit selection risk evaluation, a flexible risk evaluation method for GEO satellite frequency and orbit selection is proposed. Based on the fuzzy comprehensive evaluation method, the evaluation method supports user to configure flexibly from two aspects:index calculation mapping and weight configuration. For the difference of the index calculation mapping and weight configuration among users, a flexible construction method based on cluster analysis and normal distribution model autonomous learning is proposed. The construction method integrates the user's experienced knowledge to form the index mapping relationship and weight which most users approve, making the risk evaluation more scientific and rational. Based on the flexible risk evaluation method, the flexible evaluation system under the B/S was developed and effectiveness of the algorithm and the system is verified by actual cases.
