针对城市机动车保有量具有趋势性和不确定性的特点,结合GM(1,1)模型和马尔可夫链模型在预测研究中的优点而建立的GM(1,1)-马尔可夫预测模型,可用于城市机动车在未来年份的保有量的预测研究,且该预测经实例验证,结果令人满意。
In allusion to the characteristics of the sequence and the incertainty of city motor vehicles owned quantity, this paper presents the GM (1,1)-Markov chain forecasting model combining the merits of GM (1,1) model and Markov chain model, which could be used to forecast the city motor vehic-les owned in the future. What's more, the result through the verification of an intance is satisfying by the example of Beijing vehicles owned forecast.
