摘要
灰色系统理论中的新信息对认知的作用大于老信息的作用,而传统的累加生成没有体现原始数据中新信息的重要性。为了充分利用新信息,本文结合工程实例将加权灰色系统理论GM(1,1)模型应用于滑坡工程进行变形预测,而且对权的选取做了初步讨论,从预测结果和实测结果进行对比分析,加权累加生成的GM(1,1)模型的模拟和预测精度比传统的GM(1,1)模型模拟和预测精度高,从而说明了该法的有效性和实用性。
Based on the priority principle of new information in grey system theory,the new information counts much in information cognition to the old.However,the traditional GM(1,1) model does not reflect the importance of the new information.In order to take full advantage of new information,weighted GM(1,1) model is applied to predict landslide deformation works.A preliminary discussion on the selection of weights is given.From the predicted results and measured results of comparative analysis,the weighted GM(1,1) model has better accuracy than that of the traditional GM(1,1) model and shows its efficiency and practicality.
