Study of Low-Altitude Emergency Response Alternative Selection Process

To address the complexity of the departmental coordination with others effectively, an approach for selecting emergency alternatives based on multi-granularity linguistic and multidivisional cooperation was presented. Firstly, multi-granularity linguistic phrases were employed to express the preference information, and some transformation functions were used to unify the multi-granular linguistic phrases into a uniform linguistic label set. Secondly, the evaluation indexes of key attributes with respect to each combination of alternations were determined considering multidivisional cooperation. Furthermore, according to the evaluation indexes and the weight vector of key attributes, the comprehensive value of each combination alternative was determined to obtain the best alternative. Finally, a case study of low-attitude airspace emergency rescue after an earthquake is presented to illustrate the validity of the approach.
