【摘要】：对区域物流产业中满足用户需求的预测,可更好的分析区域物流产业的发展情况。因此,需要对非线性回归问题进行优化求解,完成区域物流产业满足用户需求的预测。传统方法融合于最小二乘法组建区域物流产业需求方程,对区域物流产业需求进行拟合,但忽略了对其拟合结果进行优化求解,导致预测精度低。提出区域物流产业满足用户需求预测算法。上述算法先组建区域物流产业经济状态时间序列模型,计算出区域的物流需求量,融合于支持向量机理论给出影响区域物流发展的主要因索,将需求预测问题转换为区域物流产业经济非线性回归问题,将区域物流产业需求数据映射至高维的特征空间,对非线性回归问题进行优化求解,依据结果完成对区域物流产业满足用户需求预测。实验结果表明,所提算法精度高,为保障物流产业与区域经济协调稳定发展提供了科学的依据。
[Abstract]:The forecast of meeting the customer's demand in the regional logistics industry can better analyze the development of the regional logistics industry. Therefore, the nonlinear regression problem needs to be solved optimally. The traditional method is combined with the least square method to set up the regional logistics industry demand equation and fit the regional logistics industry demand. But neglecting the optimization of the fitting results, the prediction accuracy is low. A forecasting algorithm for regional logistics industry to meet the needs of users is proposed. Firstly, the economic state time series model of regional logistics industry is established. The demand of regional logistics is calculated, and the main factors that affect the development of regional logistics are given by integrating the theory of support vector machine, and the problem of demand forecasting is transformed into the problem of nonlinear regression of regional logistics industry economy. The regional logistics industry demand data is mapped to the high-dimensional feature space, the nonlinear regression problem is solved optimally, and the customer demand forecast of the regional logistics industry is completed according to the results. The experimental results show that. The proposed algorithm has high accuracy and provides a scientific basis for the coordinated and stable development of logistics industry and regional economy.
