提出了一种基于初始值和背景值同时优化的新GM(1,1)模型,利用广东省梅毒年发病率预测作为研究对象,用以验证所提模型的有效性和准确性,通过计算实例验证了优化模型具有较高的预测和模拟精度.
A new GM (1,1) model based on the initial value and the background value is proposed. By using the annual incidence of syphilis in Guangdong Province as the research object, the validity and accuracy of the proposed model are verified. The optimization model is verified to have high prediction and simulation accuracy.
