A Scenario Representation Model for Emergency Decision Support

In this paper, a scenario representation model for emergency decision-making support is developed. It consists two components which are formal description of object and formal description of emergency status related to the object. Conceptual architecture of the model is also discussed. Advantages of this scenario representation model lies in four aspects: flexibility in describing dynamic evolution of emergencies; helping in define certain scenario and clarify its boundary; universal representation which contributes to similarity assessment. Moreover, the scenario representation model developed in this paper helps in evaluating emergency severity and effectiveness of decisions.
