Abstract:

Since the response of complex emergencies depends on the comprehensive prediction and evaluation, there is increasing attempts to compose multi across-domain models to find details for decision making. In this paper, a four-layer framework is proposed to support the model integration. In this framework, the universal communication between four layers respectively named as Scenario space, Task network, Model composition and Data interface is driven by three engines. With the help of ontology model of task, model and data, the system can semantically search, select and compose models. This framework has capability of supporting model integration dynamically. The results of integrated simulation case indicate that this approach can provide effective support for complex emergency decision making.

Key words: complex decision making, complex emergency, ontology, model composition
