该文研究了Ek/G/1排队系统等待时间W(t)和队长L(t)的Harris遍历、几何遍历和一致遍历.首先作者利用判别法给出了W(t)的h-骨架链的几种遍历性的充要条件.由此得出W(t)的相应结果,然后在W(t)的结果的基础上,利用小集的方法得到了队长L(t)的这几种遍历性成立的充要条件.
In this paper, the authors study Ek/G/1 queueing system via drift criterion and petite set. The sufficient and necessary conditions of Harris ergodicity,l-ergodicity and geometric ergodicity of queue length L(t) are obtained, and the authors prove that it is not uniformly ergodicity.
