本文研究服务员休假结束立即启动系统的带启动时间的单重休假M/G/1排队系统,使用全概率分解技术和拉普拉斯变换等工具,讨论系统在任意时刻t队长的瞬态分布和稳态分布,得出瞬态分布的拉普拉斯变换表达式和稳态分布的递推表达式.同时,给出稳态队长和稳态等待时间的随机分解结果.最后,通过数值计算实例讨论附加平均队长和附加平均等待时间对系统参数的敏感性.
This paper studies the M/G/1 queueing system with single vacation and setup time,in which the server starts its setup immediately when he is back to the system from the vacation. By applying the total probability decomposition technique and Laplace transform, the transient queue-length distribution and the steady queue-length distribution are discussed at any time t, and then the expressions of the Laplace transform of the transient queue-length distribution and the recursion expression of the steady queue-length distribution are obtained. Meanwhile, it is demonstrated that the stochastic decomposition of the steady has queue length and waiting time. Finally,by the numerical example,we discuss the sensitivity of the expected additional queue length and the expected additional waiting time towards of system parameters.
