基于响应面的BLISS改进方法

在分析研究BLISS(bi-level integrated system synthesis)方法的基础上,提出了一种BLISS改进方法,该方法在子系统级和系统级均引入基于试验设计的响应面进行近似,并设置了可调移动步长参数,不需再进行复杂的灵敏度分析,消除了BLISS方法对每步迭代优化移动步长的限制,减少了优化迭代次数和陷入局部最优的可能性.最后给出两个具体算例对上述方法进行了验证并与传统BLISS方法进行了对比,结果表明:其优化迭代次数分别减少了57.9%和70.3%,证明了该方法的可行性和有效性. 

Improved method of BLISS based on response surface

Based on the analysis of the BLISS (bi-level integrated system synthesis),an improved method of BLISS was proposed,and the response surface based on design of experiments was introduced to make an approximation in both the subsystem and the system-level meanwhile the parameters of moving step were set,making unnecessary for complex sensitivity analysis;the movement limits of each iterative optimization in the BLISS method,and the optimization iterations and the possibility of falling into local optimum were reduced.Finally,two specific examples were given to verify above method compared with traditional BLISS.The results show that the optimization iterations of above methods were respectively reduced by 57.9% and 70.3%,respectively.
