Selection of landslide treatment alternatives based on LSGDM method
To prevent the spread of the landslide disaster to the maximum extent,it is particularly important to carry out landslide disaster treatment work.The selection of landslide disaster treatment alternative is a large scale group decision-mak-ing(LSGDM)problem because a large number of experts and the general public can all participate in decision-making process.In response to this,A LSGDM method is proposed and applied to the selection of landslide treatment alternatives.First of all,the method of obtaining and handling the public evaluation information is given,and the information fusion approach of the public and experts evaluation information is given.Second,evaluation values represented by fuzzy numbers are converted into intuitionistic fuzzy numbers(IFNs),and the intuitionistic fuzzy evaluation decision matrix described by IFNs is obtained.Then,alternatives classification and ranking are done based on the said method.In this process,the identification and manage-ment of non-cooperative behavior from the expert groups are conducted.Finally,the sensitivity of parameters is analyzed,and the feasibility and effectiveness of this method are compared and verified.
