基于复杂网络的患者就医公交路径选择

Path selection of bus travel for patients' medical advice seeking based on complex networks

目的为方便患者解决就医过程中有关就医路线、时间耗费、路径长度、换乘次数等路径选择问题,本文基于复杂网络就患者就医公交路径选择进行研究。方法首先从复杂网络角度对泰安市公交线路进行建模,然后基于不同因素建立患者就医公交路径网络、公交站点网络和公交换乘网络。结果通过对三种复杂公交网络拓扑特征的理论分析与仿真计算,分别从最短路径长度、容错能力、有效性和介数等角度对路径可达性、换乘次数等因素做出患者就医公交路径选择的指导。结论患者就医公交路径选择不仅利于患者出行,也为医疗单位和公共交通部门提供参考和指导。

Objective In order to solve path selection on route,time cost,path length,transfer times in patient＇ s medical advice seeking process,we study on path selection for bus travel network based on complex networks.Methods Firstly,we model Tai＇ an city＇ s bus lines based on complex network with different factors,and then set up bus line network,networks of bus stations and public traffic transfer.Results With the theoretical analysis and simulation computation for network topology characters in the three complex networks,we offer guidance on path reachability,transfer times from shortest path length,fault tolerance,effectiveness,betweenness and so on.Conclusions This paper provides references for medical units,public transport departments and personal travel.
