Chen Mian‐yun · Kongzhi yu juece · 2004
A constructing mechanism of the system cloud gray model is analyzed. The integral generating principle of the model is proved, and its solving method is researched deeply. A continuous forecasting expressions of system cloud gray model is proposed. According to the characteristics of poor information and small sample series in database, data mining method by system cloud gray model is investigated. The results are compared with continuous forecasting and discrete reductive forecasting by an example. The virtues of continuous forecasting expressions are clarified.
