二十世纪末,计算机和通信技术均有了卓越的进步。预计现代通信网将有成千上万个能与几千用户相连的网络结点。对这样高度复杂和巨大的通信网,须有自适应和智能控制系统来支持。但通常的网络控制理论是建立在数学模式和控制程序上,面对各种动态变化的环境,近似的数学模式将使控 By the end of the twentieth century, both computer and communications technology had made outstanding progress. It is expected that modern communications networks will have thousands of network nodes that can connect thousands of users. For such a highly complex and huge communications network, there must be adaptive and intelligent control system to support. However, the usual network control theory is based on mathematical models and control procedures. Facing various dynamic changing environments, the approximate mathematical model will make the control
