以武汉港集装箱吞吐量的历史数据为依据,利用灰色预测模型科学预测未来武汉港的集装箱吞吐量。针对经典G(1,1)模型在构造过程中的缺陷进行修改,构造了修正后的G(1,1)模型,减少了原有模型的误差,提高了预测的精度。通过实例探讨了修正的G(1,1)模型在港口吞吐量方面的预测,同时验证了灰色预测模型的有效性和实用性。
Based on the historical data of container throughput in Wuhan Port, the gray prediction model is used to predict the container throughput of Wuhan Port in the future. Aiming at the defects of the classical G (1,1) model in the process of construction, the modified G (1,1) model is constructed to reduce the error of the original model and improve the prediction accuracy. Through the example, the prediction of modified G (1,1) model in port throughput is discussed, and the validity and practicability of the gray prediction model are verified.
