基于综合赋权C-TOPSIS法的航天器研制风险控制

通过对航天器研制风险评估指标的分析,建立基于综合赋权的逼近理想点法(TOPSIS)的风险控制模型.运用层次分析法(AHP)求得主观权重,熵值赋权法获得客观权重,再通过线性规划的方法求出综合权重;用"垂面射影法"替代现有相对欧式距离对TOPSIS法进行优化,提高了评估精度;对风险评价指标进行分类处理,建立分层评价指标体系,简化了运算过程.最后结合航天器研制风险控制实例,选出了较为优化的技术方案,证明了该方法的可行性.

Risk Control of the Spacecraft Development Based on Comprehensive Weight C-TOPSIS

By analyzing the risk of the spacecraft developing evaluation index， a risk control model was built based on comprehensive weight TOPSIS. In this model， the subject and the object weight were calculated by AHP and entropy-weight method. The linear programming was used to count the comprehensive weight. And TOPSIS method was optimized by using “vertical plane projection method” to substitute existing opposite continental distance， resulting in improving the precision of evaluate. The risk evaluated target was clustered， and the different sort target system was set up， resulting in predigesting the process of the operation. In the end， the best scheme was selected by combining the example of spacecraft development control. The result showed the feasibility of the developed method.
