Abstract:To deal with the heterogeneity in the cross-department integration processes for nuclear emergency system, the system elements, structures and operation logics are analyzed from the “Scenario-Task-Organization-Resource” perspective. With the technologies of Space Mapping and Ontology, the Multi-Department Integrated Space (MDIS) framework is proposed. Based on this framework, the space elements, the links and constraints of them are defined, and the MDIS structure model is constructed, and then the original problems of nuclear emergency response in physical space are transformed into the target problems of integration in the MDIS space. After that, the potential interoperability problems of the MDIS are discussed, and the relevant solutions based on constructing mediator models in MDIS are presented. Furthermore, for supporting the processes of multi-department nuclear emergency decision-making, the MDIS space reasoning system is designed based on multi-agents. Finally, with an example, the validity of this framework is verified.
