摘要
介绍了PGM(1,1)灰色系统建模原理,同时引入了一种求得最佳背景值的方法,通过与GM(1,1)灰色系统模型的比较,证明了这种方法求最佳生成系数的可行性和有效性。
The modelling of PGM （ 1,1 ） gray system are introduced, simultaneously the method of obtainning the optimal produce coefficient is introduced,through a comparison with GM （ 1,1 ） gray system model, we had proven that the of obtainning the optimal production coefficient is feasibility and validity .
