| 中文摘要: |
| 针对突发事件发生后如何进行应急决策的问题，基于应急案例的层次结构提出了应急案例的XML表示方法，解决了异构应急案例的统一表示问题．在案例检索算法中，设计了一种基于结构相似度和属性相似度的双重案例检索算法，有效克服了传统最近邻算法中由于案例属性值缺失而无法进行案例相似性计算的缺陷．台风领域案例检索算法应用过程的实例说明了案例推理在应急辅助决策中的实用性，为应急指挥者提供了一种科学而有效的辅助决策方法． |
| 英文摘要: |
| Focusing on a discussion about how to make emergency decisions after the occurrence of emergent events, a representation method based on XML is proposed based on the hierarchical structure of emergency cases, which can solve the unified representation problems of the heterogeneous emergency cases. A two-layer case retrieval algorithm combining structure similarity and attribute similarity is designed, which can effectively overcome the shortcomings of traditional nearest neighbor algorithm that fails to calculate the similarities between the cases with the missing values. Finally, the application of case retrieval algorithm to typhoon analysis is used to illustrate the practicality of case-based reasoning (CBR) approach in emergency aid decision-making, which is testified a scientific and effective aid decision-making method for the emergency officials. |
