应急决策中基于问题与解关系的案例调整方法

针对应急方案调整问题，提出了一种基于案例问题与解决方案之间关系的决策分析方法.通过混合相似度法计算目标案例与历史案例间的综合相似度，并将其融入历史案例的问题与解决方案属性中，进而根据向量余弦夹角定义计算问题与解决方案之间的关系.应急方案调整除需考虑问题与解决方案之间的夹角关系，还需考虑问题与解决方案的模的大小.最后，用算例说明该应急案例调整方法的有效和实用性.

A case adaptation method based on problem-solution relation for emergency decision making

This paper proposes a decision analysis method based on the problem-solution relation of similar cases to support the emergency alternative adaptation. The overall similarity between the target case and historical cases can be calculated by adopting a hybrid approach, it is then integrated into the attributes of historical cases' problem and solution, relation of historical cases', we can estimate the relation between the problem and solution based on their cosine angle. The adaptation of the emergency alternative should take accout not only on the angle relation between the problem and the solution, but also the size of the module. Finally, a numerical example is provided to illustrate the feasibility and validity of the proposed emergency case adaptation method based on the problem-solution relation.
