Synthetic ranking evaluation of flood disaster based on grey-cloud whitening-weight function
Yue Chen · Ziran zaihai xuebao · 2013
This paper improves the traditional whitening-weight function by introducing the cloud model,a representation that could take bi-directional conversion between qualitative and quantitative determination of fuzziness and randomness.With the improvement,a grey-cloud clustering model was proposed for the synthetic ranking evaluation of flood disaster.The novel method is then applied to evaluate 45 flood disaster cases of several provinces in 1989-1999,evaluating the amount of building collapse,affected area,number of victims,and direct economic loss.Results showed that this method is rational and usable for flood disaster evaluation.
