根据长话网上话务量在未来一段时期内的发展趋势,结合网路中现有设备情况,制定出合理的长话网路结构、传输电路分配、交换设备的配置,使用最少的网路建设投资来完成网上话务量的疏通,并达到话务量传输的畅通、准确、迅速、可靠的要求是长话网路优化所研究的问题。长话网路优化问题的数学模型为多目标、多约束条件的非线性规划问题,要直接求得最优解十分困难。为此,研究长话网优化的近似方法是人们所关注的问题。求近似最优解一般
According to the development trend of long distance internet traffic in a period of time in the future, a reasonable long-distance network structure, distribution of transmission circuit, configuration of switching equipment, network construction with minimum use Investment to complete the online traffic unblocked, and to achieve the smooth flow of traffic transmission, accurate, rapid and reliable requirements of long-distance network optimization is the study of the problem. The mathematical model of long-distance network optimization is multi-objective and multi-constrained nonlinear programming. It is very difficult to find the optimal solution directly. For this reason, the approximate method of optimizing the optimization of the long-distance network is a matter of concern. Find approximate optimal solution in general
