GM(1,1)模型在市场需求预测中的应用

主要针对系统中行为信息不完全,企业中的人事管理运行机制不明确等问题,运用灰色系统一维情况来建立控制模型。该模型具有需要的原始数据较少、精度高等特点,而且操作简单易行。市场需求量是一个明显的灰色系统,用该方法进行预测,能比较精确地描述客观事物的发展变化,并可预测其变化规律,以便供决策部门参考。结果表明该模型预测值与实际值的拟合程度较好,达到了较高的精度。

Application of forecasting requirement of market based on GM(1,1) mode of the time order

In view of the incomplete behavior information in system,and indeterminacy of the personnel management system in enterprise, a control model is set up using fuzzy gray system. It needs only a few original data, and gives high accuracy in results. Moreover, it is easy for people to use this method. Since market requrement is a gray system, using this model can describe development of objective things preciser in order to provide a referrence for decision-making department.The result show that the model corresponds more to practicality and attains high precision.
