当前,人们在作经济预测或人才预测时,常常用到灰色系统理论(Grey System),因为对于中长期预测来讲,用建立在灰色系统理论基础上的数学模型(称灰色模型)较之其他预测方法更为准确、可靠,且涉及的相关变量要少。本文就是根据灰色模型的建模方法,编制了一套计算机软件,从而加快了运算的速度和保证了精度,有广泛的应用价值。(以下简称灰色模型为GM模型。)。一、GM模型的建模方法 GM模型(Grey Model)是以灰色系统理论作为基础的。所谓灰色系统,是指信息由部份明确(白色模块),部份不明确(灰 At present, people often use the Grey System theory when making economic predictions or talent predictions because, for medium and long-term predictions, mathematical models based on grey system theory (called gray models) are used The prediction method is more accurate and reliable, and involves fewer relevant variables. This article is based on the gray model of the modeling method, a set of computer software, which speeds up the calculation speed and guarantee the accuracy, has a wide range of application value. (Hereinafter referred to as the gray model for the GM model.). First, the modeling method of the GM model The GM model (Grey Model) is based on the grey system theory. The so-called gray system means that the information is partially clear (white modules) and partially unclear (grey
