摘要/Abstract

摘要：

针对突发事件的响应决策，借鉴以往发生的同类型案例应急处置决策经验是一种比较良好的决策处置方法，另一方面，突发事件案例的复杂性造成案例利用困难。将案例推理方法运用到对复杂突发事件的研究非常重要。本文在设计两层案例检索结构的基础上设计案例检索算法，以提高检索及匹配精度，实现高效的案例检索以用于突发事件的决策支持。

Abstract:

In response to emergencies, learning from those previous similar cases and experiences is a relatively good decision-making method for emergency management. On the other hand, in light of the complexity of disaster cases which may contain lots of scenarios and attributes in different stages of disaster development, it's very difficult to utilize these cases for real situations without subtle processing. The application of case-based reasoning method to the study of complex emergencies is of great importance. Recent researches have proved that scenario-based reasoning is much more efficient than case-based reasoning. This paper develops case retrieval algorithms on optimized hierarchical case retrieval structure. In order to improve the accuracy and efficiency of case retrieval and decision-making process, approaches proposed in this paper are all centering on the concept of scenarios. Parts of a real case are selected to verify the effect of these algorithms.

Key words: case-based reasoning method, multi-dimensional scenario space method, case representation, case retrieval
