Research on Evaluation of Remote Sensing Satellite Equipment Capability Based on Fuzzy Influence Diagram

我国卫星产业在促进天基应用蓬勃发展的同时,也带来了研发价值、生产发展速度的挑战,对卫星装备开展全面性的能力评价具有重要意义,评价过程需要充分考虑影响因素的多元性与相依性。本文以遥感卫星装备能力评价为目标,选取包含任务规划、导航定位、军事作战等与装备能力相关的24个影响要素并构建对应指标体系,采用模糊影响图方法完成数值层及结点间模糊关系的建立,实现对遥感卫星装备能力的有效评价。以某新型装备对卫星系统装备能力影响为例进行了评价验证分析,并给出相应的对策建议。结果表明,该评价方法能够对卫星装备能力做出有效评价,较好地反映装备能力受要素的影响,数据结构更便于计算,可为遥感卫星产业的装备研发提供决策支持。

While promoting the vigorous development of space-based applications,China’s satellite industry has also brought challenges to the value of research and development and the speed of production development.It is of great significance to carry out comprehensive capability evaluation of satellite equipment,and the evaluation process needs to fully consider the diversity and interdependence of influencing factors.Aiming at the evaluation of remote sensing satellite equipment capability,this paper selects 24 influencing factors related to equipment capability,including mission planning,navigation and positioning,military operations and so on,and constructs the corresponding index system.The fuzzy influence diagram method is used to complete the establishment of fuzzy relations between numerical layers and nodes,so as to realize the effective evaluation of remote sensing satellite equipment capability.Taking the impact of a new type of equipment on the satellite system equipment capability as an example,the evaluation verification analysis is carried out,and corresponding countermeasures and suggestions are given.The results show that this evaluation method can make an effective evaluation of the satellite equipment capability,better reflect the influence of the equipment capability by factors,and the data structure is more convenient to calculate,which can provide decision support for the equipment research and development of remote sensing satellite industry.
