基于瓶颈分析的邮政速递网络的优化

Optimization of a postal express mail network based on bottleneck analysis

从速递网的构建目标、问题范围、时限及频次规定、车辆因素、运行成本、经转次数上限、时限达标率等方面对邮政速递问题进行了系统地分析,对运用最小时限邮路搜索算法构建的网络进行瓶颈分析,以获取满足规定时限标准的邮政速递网络的最优实现.实验仿真结果表明该网络构建方法具有实用性好、通用性强等特点,结论对邮政企业制定邮件发运计划及调整邮路等提供了良好的决策支持.

The postal express delivery problem was systemically analyzed in terms of its construction objectives, ranges, and time limit and frequency, vehicle factors, operation costs, upper limit of transiting times, time limit satisfying ratio. Bottleneck analysis was applied to the network constructed by the minimum time limit searching algorithm, and the optimal postal express mail network that meets the specific time limit satisfying ratio was obtained. Simulation results indicate that the construction method does well in practicability and adaptability, which provides decision support to the postal enterprise in planning and making post road adjustments.
