本文以港口货物吞吐量为预测对象,根据港口物流系统的特点及模型特征,选择灰色预测模型、回归模型作为单项预测模型对上述对象分别进行模拟、预测,然后运用组合预测方法预测出上海港口货物吞吐量的未来发展状况,得到了较好的效果。 In this paper, we take the port cargo throughput as the forecasting object. According to the characteristics and model characteristics of the port logistics system, we select the gray forecast model and the regression model as the single forecasting model to simulate and predict the above objects respectively, and then use the combined forecasting method to predict the Shanghai port cargo The future development of throughput, get better results.
