基于粗糙熵模糊决策的河道采砂交易模式选择研究——以鄂赣边界可采区为例

Study on Selection of River Sand Mining Modes Based on Rough Entropy Fuzzy Decision Model——Taking Workable Sector of E and Gan for Example

在分析我国河道采砂交易模式的政策背景和交易现状的基础上,运用粗糙熵模糊决策方法,建立针对直接许可、招标和拍卖三种交易模式的优选模型,对鄂赣边界可采区采砂交易模式进行选择。结果表明:该河段最佳交易模式为招标。由此得出结论:粗糙熵模糊决策法遵循河道采砂交易基本原则,对采砂交易模式的选择可行且有效。

On the basis of the analysis of policy background and trading status of China＇s river sand mining modes,the optimized model of sand mining is established based on rough entropy fuzzy decision model for three modes such as direct permission,bidding and auction.Through applying the model to select the sand mining modes in the workable sector of E and Gan,it is shown that the best mode for this area is bidding.In conclusion,the rough entropy fuzzy decision could follow the basic principles of sand transaction,and the method is feasible and effective for the selection of sand mining modes.
