Improving Non-equidistance GM(1,1) Model's Grey Differential Equation
並列摘要
Through analyzing the non-equidistant GM(1,1) models modeling mechanism, by using the Lagrange mean value theorem, the paper find it equal derivative. And get the white differential equation distributed in the mathematics model. Hence, we can get a new grey differential equation, and could match the white differential equation. Based on the analysis of indicator function, the parameters a and b can get in the first, then use the twice accumulation method to get parameter c. By the realistic examples, the result is proved to be precise and reliable.
