摘要: 提出一种校正AMG方法来求解排队模型。该方法对一般AMG方法的限制算子进行了改进,从而在求解过程中保留了问题的奇异性。计算结果表明改进后的方法加快了收敛速度,提高了解的精度。

Abstract: A modified algebraic multigrid (AMG) method for queueing networks is presented.The method keeps the singularing of queueing networks by modifying the restriction operators.Numerical results indicate that this method is more efficient and robust than conventional AMG method.

Key words: Modified AMG Methods, Queueing Networks, Numerical Methods
