摘　　要：分析一种在通讯网络中进行拥塞管理的经济模型。这个模型由用户的效用函数和用户对拥塞的延时敏感函数组成,并引入经济学中边际消费的概念来分析网络系统的全局最优性。通过分析表明当用户的效用函数均为线性且用户对延时的敏感系数不等时所得到的全局最优点不是内点,即资源没有达到最优分配,这可由改变效用函数的形式和使用户对延时的敏感系数相等来弥补。数值算例说明了此种分析方法的正确性。This paper analyzes an economic model of congestion control for a communication network. The model consists of the users＇ utility functions and the functions of users＇ sensitivity to delay. It applies the concept of marginal-cost pricing to analyze the global optimality of the system. From the analysis, it shows that the interior point is not the global opti- mal point when the users＇ utility functions are linear and the coefficients of the sensitivity to delay are not the same, so the resource allocation is not optimal. This can be settled by choosing some proper utility functions and making the sensitivity of the users＇ to delay be same. Numerical examples certifies the validity of the analysis.
