摘 要: 分析了假日旅游信息特征,引入了效用函数的概念,建立了适用于假日旅游大系统流量预测的广义模型。将假日旅游流量预测模型进行了非线性推广,通过极大似然法和RBF神经网络分别对线性流量模型和非线性流量模型进行了预测。 The tourism holiday information characteristics were analyzed, and the avail function was introduced to build up the generalized model used in the large scale system flow prediction of holiday tourisms. Nonlinear extension of the flow prediction model for holiday tourism was made. The linear and nonlinear flow models were predicted by maximum likelihood and RBF neural network respectively.
