一类优化离散灰色模型及其等价模型
A Class of Optimized Discrete Grey Models and Its Equivalent Models
摘要
Abstract
By letting three modified forms αx(1) ( 1 ) ,αx(1) (m) and αx(1) (n) be the initial iterative datum value respectively,three optimized discrete grey models are put forward, and the forms of discrete grey model are extended.Then the authors prove the equivalence of the three optimized discrete grey models and three known optimized discrete grey models with the initial iterative datum value x(1) ( 1 ) +β,x(1) (m) +β and x(1) (n) +β respectively, and the equivalence of the two classes of optimized discrete grey models not only reveals that a essential connection exists between them, but also provides the greater choosing space with application of optimized discrete grey model.关键词
