灰靶决策在水库移民安置点优选中的应用

Application of Grey Target Decision in the Reservoir Resettlement Optimization

移民是水利水电工程建设中不可避免的问题之一,对移民的安置关系到工程建设的成败.安置区进行优选,有利于移民社区今后的稳定和发展.由于灰色系统考虑了信息的不完备性和不确定性,应用灰靶决策法选择移民安置区更具有客观性、科学性.介绍了灰靶决策法的求解步骤,结合丹江口水库在河南某县安置点的选择,着重探讨了灰靶决策法在安置点优选中的应用,并进行了加权灰靶决策分析,根据靶心距确定了最优安置点,为其他水库工程的移民安置点选择提供了依据.

The migration is an inevitable question in the construction of water conservancy and hydropower projects. Immigration resettlement is related to the success or failure of project construction. Optimization of the relocation ar- ea is beneficial to the immigrant communities stability and development in the future. Because of the grey system considering the incompleteness and uncertainty of information, thus the grey decision is more objective and scientif- ic in choosing resettlement area. The process of the grey target decision is introduced, combining with the site se- lection of Danjiangkou Reservoir in some county of Henan. The application of grey target decision in site selection is discussed, and the weighted grey target decision analysis is carried out. According to the distance to target, the optimal site is determined. The basis for other similar projects site selection is provided.
