灰色Verhulst模型的优化及其应用

Optimization of Grey Verhulst Model and Its Application

针对灰色Verhulst模型的优化单一,多种优化不能有效结合的情况,在同时优化背景值和初始值的基础上,建立将两种优化相结合的灰色Verhulst模型。利用该模型对我国手机网民增长规律进行研究,结果表明,优化灰色Verhulst模型具有较高的精度。

According to the fact that there exists simple optimization method and types of optimization without effective combination.By optimizing simultaneously background values and initial values,we build an optimized grey Verhulst model.Based on the model,we research Chinese mobile internet-user growth.The result indicates that the optimized grey Verhulst model can achieve more satisfactory precision than traditional grey Verhulst model.
