Cross-domain integrating and reasoning spaces for offsite nuclear emergency response

To solve the problems of heterogeneity and disorder in the cross-domain integration processes for offsite nuclear emergency response, the integrated decision-making framework of the CDIRS spaces based on Space Mapping and Semantic Web is proposed. Under this framework, the method of feature mapping and space modeling, interoperable mediating and interoperability verifying, ordered integrating and reasoning, which are key steps of the CDIRS method, are presented. Furthermore, with a fictive nuclear accident scenario, the relevant CDIRS spaces and ordering rules are constructed, and then the appropriate cross-domain integrated response solution is obtained and verified effectively by reasoning and simulating in the CDIRS model. With the CDIRS method proposed in this paper, the heterogeneity and disorder can be avoided, and the targets and constraints of the offsite nuclear emergency response problems in the original space can be transformed into the target space, being processed unified by formal modeling and ordered reasoning.
