摘要
讨论了在计算机网络通信等系统中 ,采用简单而切实可行的周期输入来进行控制时 ,离散事件系统的动态行为 .结果表明 :若采用周期输入 ,则系统的状态变量也呈周期性 .当输入周期 μ大于系统的固有周期λ时 ,系统的状态也以 μ为周期 ,且有一定的抗抖动的能力 ;当 μ等于λ时系统利用率最高 ;当 μ小于λ时 ,系统将不堪负重产生阻塞 .
We study the performance of a discrete event system when using periodical input which is simple and practical especially in computer communication network. The result shows that the state vector is also periodical if the input is. Given that μ and λ are the periods of input and system respectively. When μ is greater than λ, the period of state vector is also μ and the system will have good resistibility from disturbance to some extent. If μ is equal to λ, the utilization is the best. If μ is lower than λ, the system is overload and will have a congestion.
