故障情况下电话网路由的优化算法

The Telecom Network Routing Optimization Algorithm for Sudden Failures

在我国长途电信网将要实行的固定无级选路方式的前提下，以话务生存率最大为优化目标，提出了故障情况下电话网路由优化模型与算法，模拟实例表明，提出的路由修正算法比重新设计路由表具有更强的实用性．

In the condition that fixed and non hierarchical routing which will practiced soon in our country's toll telecom network , we bring up a new optimization algorithm with mathematical model for sudden failures of telecom network solving the problem of service restoration .The optimization model aims at the maximum living rate . Through practice simulation we show that the algorithm of routing modification is better than the algorithm of routing a new design for its practicality.
