摘要
地震突发事件具有紧迫性、破坏性和信息不完备性,给人民群众生命财产安全造成了重大危害。案例推理是处置突发事件的有效方法。其中,案例表示是案例推理的基础,但是目前的案例表示方法并没有考虑突发事件的信息不完备性。这削弱了突发事件应急案例表示效果,并影响案例检索的准确性和案例适配的效果。本文在研究案例表示方法的基础上,结合案例推理的结构化和定量化需求,将证据理论的基本信任分配函数引入框架表示法中,提出了信息不完备条件下地震应急案例的框架表示法。接下来,本文提出了信息不完备条件下地震应急案例检索方法。最后,文章对提出的信息不完备条件下地震应急案例的结构化方法进行了应用验证。
Earthquake emergencies are characterized with urgency,destruction and incompleteness of information,and do a great harm to the safety for people's lives and property. Case-based reasoning is an effective method for emergency disposal and case representation is the basis of case-based reasoning. However,the current methods of case representation are not involved in the incompleteness of information for emergencies,which weakens the effectiveness of emergency case representation and affects the accuracy of case retrieval and the effect of case adaptation. On the basis of case representation research,this paper introduces mass function of evidence theory into the framework representation method and propose the framework representation method for earthquake emergency cases under the condition of incompleteness insormation according to structured and quantitative requirements of case-based reasoning. Then it puts forward retrieval methods for earthquake emergency cases under the condition of incompleteness information. Finally,it the proposed case representation and retrieval method for earthquake emergency cases under the condition of incompleteness information is verified for application.
