针对复杂条件因素影响下混凝土坝浇筑仓位排序过程的不确定性问题,提出了一种基于灰色关联和证据推理的仓位排序方法.以全体可浇筑仓位作为对象识别框架,利用浇筑仓位的各属性指标作为证据源,通过计算指标特征值的灰色关联系数求解指标的信息不确定度,实现浇筑仓位选择指标的基本概率分配,构建识别仓位浇筑优先级的证据体,采取Dempster合成法则的证据融合确定浇筑仓位.最后,结合工程实例验证了方法的可行性和有效性.
Aiming at the uncertainty of the sorting process of concrete dam placement positions under the influence of complicated conditions, a position ranking method based on gray relation and evidence reasoning is proposed. Taking all the positionable positions as object recognition framework, As the source of evidence, the gray relational coefficient of the eigenvalues of the index is used to solve the uncertainty of the index information, to realize the basic probability assignment of the selection index of the pouring position, to construct the evidence body for identifying the priority of the pouring position, and to determine the pouring by Dempster’s law of combination Finally, combined with engineering examples, the feasibility and effectiveness of the method are verified.
