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

After scenario analyzing, based on the method presented in Section 3, the ‘‘event–task–resource” are mapped into element subspace, and the CDIRS space structure model is constructed as shown in Fig. 11analyzing the validity and the interoperability of the reasoning result of this case.

Furthermore, with a fictive nuclear accident scenario, the relevant CDIRS spaces and ordering rules are constructed, and then the appropriate cross-domain integrated response

is obtained and verified effectively by reasoning and simulating in the CDIRS modelA fictitious example (the scenario ‘‘A” shown in Fig. 1) is used here to illustrate the principle and the implementation process of CDIRS: In this scenario, a disaster chain is caused by a nuclear accident ‘‘cooling system failing”; and it has rapidly evolved from ‘‘core melting” to ‘‘containment broken”, and then from ‘‘containment broken” to ‘‘radiation leaking” event which may cause a large number of casualties.

For the restrictions in experimental conditions, in this paper, we only consider some ideal disaster scenarios, integration demand, and focus on the principal study, example analysis and reasoning experiment.

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.(1) The ‘‘feature mapping and space modeling – interoperable mediating and interoperability verifying – ordered integrating and reasoning” based CDIRS framework is proposed for offsite nuclear emergency response. (2) Under the CDIRS framework, the concrete space mapping and modeling principles are presented, and then the integrated decision-making problems can be mapped from the original space into the CDIRS spaces; (3) To solve the possible interoperability problems of the cross-domain integration processes, relevant interoperable mediator models and interoperability verifying methods of the CDIRS spaces are proposed; (4) The CDIRS spaces ordering principles and relevant basic reasoning rules are defined for obtaining the integrated cross-domain nuclear emergency response solutions; (5) the formally expression and achievement method based on the protégé tools is presented.

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
