摘 要:在建立系统数学模型与定义系统参量的基础之上,以嵌入马氏链和概率母函数为数学工具,对离散时间型、双队列的非对称性门限服务系统进行精确解析,推导出系统的一阶、二阶特性以及循环周期,精确推演出信息分组平均排队队长和平均等待时延,计算机仿真实验与理论分析计算具有较好的一致性。该分析进一步加深了对非对称门限轮询系统的认知,为非对称门限轮询系统问题的研究奠定了基础,对更佳灵活便捷的控制轮询系统有着积极意义。Based on establishing the mathematical model of the system and defining the parameters,using the embedded Markov chain and probability generating function as Probabilistic methods, the discontinuous-time,two-queue different gated polling system has been fully analyzed,the low-and higherorder properties and cycle period of the system are deduced,and the average queuing length and average waiting delay of information packets are calculated accurately. The simulation experiments agree well with the theoretical calculations. The analysis further deepens the cognition of the asymmetric threshold polling system,lays a foundation for research on the asymmetric threshold polling system,and has a positive significance for a better and more flexible control polling system.
