基于TOPSIS的卫星数传调度策略评价方法

Evaluation Method of Satellite Data Transmission Scheduling Strategy Based on TOPSIS

卫星数传调度策略评价是一类多属性决策问题。对调度策略的选用和提升有重要的理论意义和实际价值。在介绍了卫星数传调度模型和调度策略原理的基础上,构建任务调度实例,获取了调度方案和算法运行的数据。根据所建评价指标体系,应用TOPSIS法综合评价卫星数传调度策略。评价结果表明,STK/Scheduler的五种调度策略的求解能力和适用范围存在较大差异。基于TOPSIS法对卫星数传调度策略进行评价,具有一定的可行性和科学性,能够为调度策略的选择提供参考依据。同时对复杂调度策略的评价有借鉴作用。

Evaluation of satellite data transmission scheduling strategy is a kind of multiple attribute decision making problems with a very important significance for selecting and improve scheduling strategy. Data of scheduling schema and algorithm running on the basis of discussion of satellite data transmission scheduling model and feathers of scheduling strategy principle are got. According to the created evaluation index system, overall evaluations of sat- ellite data transmission scheduling strategy with TOPSIS are maken. The results of evaluation method show that there is a big difference between five scheduling strategies of STK/Scheduler in solving ability and scope of application. Evaluation of satellite data transmission scheduling strategy based on TOPSIS can offer valuable references for selec- ting scheduling strategy and has some reference for evaluation of complex scheduling strategy with feasibility and scientific nature.
