熵权决策法在滑坡治理方案优化选择中的应用

针对滑坡治理方案优化选择的复杂性及不确定性,充分考虑地质资料、施工条件、工程经济及环境影响等综合因素,构造多目标优选模型。该模型根据各方案、各指标构成判断矩阵,并利用指标值确定其熵值。根据各方案与理想点的贴近度对方案排序,从而选出最优方案。据此方法并结合VB编制的基于熵权的多方案优化选择程序,能够方便地对各方案作出综合评价。通过对康家咀滑坡治理方案的优化分析,证明基于熵权的滑坡治理方案优选,具有简便、定量、严密的特点和较强的识别评判能力。该方法对其他综合评价工作也有一定的借鉴意义。

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 t...
