The Method and Application of Fuzzy Optimal Theory and Entropy Weight Decision-Making Method in Landslide Treatment Schemes Selection

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,构造多目标多层次优选模型。该模型首先根据模糊优选理论生成判断矩阵,后用熵权决策法确定优选方案。根据此方法并结合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,证明基于模糊优选理论和熵权决策法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具有一定的借鉴意义。

In view of the complexity and uncertainty of optimization selection of the landslide treatment scheme, taking geological data, execution conditions, engineering economy, environmental influence and etc. factors in full consideration, the multi-objective and multi-layer optimal model is established. The model first generates judge-array based on fuzzy optimal theory ; and latter determines the optimal plan with the entropy weight decision-making method. Under this method combined with the preparation of the VB based on the fuzzy optimal and the entropy power multi-scheme optimization selection program, it is convenient to make the quality synthetic evaluation to various schemes. Through the Kang-Jiazui landslide treatment scheme＇s optimized analysis, it is proved that on the basis of the fuzzy optimal theory and entropy weight decision-making method, the optimal selection is of simple, quantitative and strict characteristics and has the strong ability of recognition and judgment. This method also has certain referential significance to other synthetic evaluation work.
