基于Logistic增长模型的城乡协同物流网络优化

Urban and Rural Collaborative Logistics Network Optimization Based on Logistic Growth Model

物流承运人组建物流联盟的关键问题是互动机理的合理性,引入Logistics增长模型来描述城乡物流联盟中承运人之间相互作用过程,得出联盟成员合作获得共赢是依赖彼此间相互作用系数的选择。并运用Logistics模型及基于"订单共享"的合作机制构建城乡物流协同网络运作模型,采用模拟退火算法找出联盟成员间最优的相互作用系数,最后通过算例和实验数据分析表明此验证了模型的有效性。

The key problem of logistics carriers in establishing logistics alliances is the rationality of the interaction mechanism. The Logistics growth model is introduced to describe the process of interaction between carriers in urban and rural logistics alliances,and it is concluded that the cooperation of alliance members to achieve a win-win situation is dependent on the interaction coefficient between them. And using Logistics model and cooperation mechanism based on＂order sharing＂to build the operation model in urban and rural logistics collaborative network,using simulated annealing algorithm（ SA） to find the optimal interaction coefficient among the alliance members. Finally,the validity of the model is verified by a numerical example with the experimental data analysis.
