| 摘 要： | 针对贪婪式中断评估函数所确定的系统中断位置为局部最优解的问题,提出了新的中断评估函数,该评估函数从全局优化的角度分析中断问题,通过考虑中断对整个诊断过程的信息景和费用带来的影响,能够获得更优的中断位置,并基于此中断评估函数对多回路系统诊断策略的优化算法进行了改进,给出了算法实现的主要步骤;通过仿真实例证明了该方法对多回路系统诊断策略优化的有效性.

| Abstract: | According to the problem that the breaking position based on the greed breaking evaluation function is local optimal solution,the new breaking evaluation function is proposed.This function analyse the multi-loop system from the manner of global optimization and considering the effect of the whole diagnosis information quantity and cost made by the breaking can get more optimal breaking position.Based on the function,the diagnostic strategy optimization arithmetic for multi-loop system is improved,the main p... |
