Grey GM(1, 1|sin) power model based on oscillation sequences and its application(基于振荡序列的灰色GM(1,1|sin)幂模型及其应用)

针对现实中普遍存在的振荡序列预测问题,传统灰色模型的预测效果并不理想。为此,在现有灰色GM (1,1|sin)模型基础上,提出了GM(1,1|sin)幂模型,给出了最小二乘准则下的参数计算公式;构建了以平均模拟相对误差最小化为目标的非线性优化模型,利用粒子群优化算法求得最优参数。最后,将新模型应用于城市交通流和高新技术产品出口额模拟预测,并将预测结果与传统GM(1,1)模型、GM(1,1)幂模型和GM(1,1|sin)模型进行了比较,结果表明,新模型具有更高的模拟精度,更适合对振荡序列的预测分析。...
