Application of Entropy Weight Decision-Making Method to the Optimal Selection of Landslide Treatment Scheme

Aiming at the complexity and the uncertainty of optimal selection of landslide treatment scheme,taking the geological data,execution conditions,engineering economy,environmental influence and etc.synthetic factors fully into consideration,the multi-objective optimal model is constructed.This model forms the judge-array according to various schemes and indexes;furthermore,the entropy is determined by the index value.Then the schemes are lined up according to the degree how close it is with the ideal dot,so the optimal scheme is easy to be selected out.Using this method as well as the multi-scheme optimal selection program worked by VB on the base of the entropy power,it is convenient to make a synthetic evaluation of various schemes.Through the optimization analysis of Kang Jiazui landslide treatment scheme,it is proved that the optimal scheme of landslide treatment based on entropy weight has the strong recognition judgment ability.It is convenient,quantitative,and strict.This method also offers certain reference to other synthetic evaluation work.
