针对基于案例推理的应急方案生成问题,从方案有效性判断和实施效果融合两个角度出发,提出一种考虑方案有效性的应急案例决策方法.首先,依据决策者给出的预估方案生成有效的案例集,利用检索方法计算有效历史案例与目标案例的相似度;然后,根据距离熵方法对多时期的方案实施效果进行融合,集结相似度和实施效果,进而得到每个案例的综合评价值,并根据综合评价值的大小确定最优备选方案;最后,通过一个高层建筑火灾算例验证了所提出方法的可行性和有效性.
Aiming at the generation of contingency plans based on case-based reasoning, this paper proposes a decision-making method of emergency cases considering the effectiveness of the programs from the perspectives of judging the validity of the programs and implementing the effects .Firstly, an effective decision-making method based on the decision- Then, according to the distance entropy method, the effect of multi-period project implementation is converged to build the similarity and implementation effect, and then the comprehensive evaluation value of each case is obtained. , And determine the best option according to the size of the comprehensive evaluation value. Finally, a high-rise building fire example is used to verify the feasibility and effectiveness of the proposed method.
