摘要
文章对社会上老龄化问题涉及到的养老服务工作中的特性化物流配送问题进行了简单分析,建立了相应的带软时间窗的车辆路径问题模型。简明介绍了PSO算法的原理,并利用标准PSO和改进PSO对模型进行了求解和比较,表明PSO算法能较快获得优化结果。
The article simply analyses the logistics distribution problem vices fi,r the aged, and a vehicle routing problem model with soft time the principle of PSO algorithm, the basic model of the vehicle routing rilhm. It indicated that the improved PSO algorithm can obtain optimal of characteristic, which is related to the aging society ser- windows has been established. After a brief introduction to problem was solved using the standard and improved algo- results quickly.
