Grey system theory is based on the relevance of space, smooth discrete function defined concepts such as derivative and ash gray differential equation, then the discrete form of the column to establish a dynamic model of differential equations, as this is intrinsic in the basic model of gray system, and the model is similar , non-sole, so the gray model for this model, denoted as GM (Grey Model), the gray model through the use of discrete random number generation is significantly weakened into a stochastic and build a few more laws, and establish the Differential Equation of the model, it is easy to carry out their research and describe the process of change.
