移动冷库嵌入的共享共配冷链配送服务网络研究

城市冷链配送的“最后一公里”问题一直是高质量冷链物流服务的瓶颈。移动冷库的出现扩展了固定冷库的服务半径，显著降低了断链的概率。虽然移动冷库的嵌入提高了冷链配送的时效性，但是也导致该问题更加复杂，特别是移动冷库存在供需可变的双重属性，导致传统方法难以准确刻画移动冷库的布局时空变动与其供需角色转换间的关联性。本项目构建移动冷库嵌入下的配送路径链式结构拓扑，并对多行程关联路径进行解耦，提出链式配送路径规划方法。挖掘移动冷库在仓储补充网络和客户配送服务网络间的动态衔接机理，构建基于关键节点动态衔接的两级配送服务网络协同优化方法。进而，研究多个运营商对移动冷库资源的博弈过程，构建移动冷库共享共配服务网络协同优化方法。本项目提出短链视角下的移动冷库共享共配理论和方法，对实现城市冷链高质量配送，推广“移动冷库+集配中心”模式具有非常重要的理论意义和广泛的实用价值。

The “last mile” of urban cold chain distribution has been the bottleneck of high-quality cold chain logistics service. The mobile cold storage could expand the service radius of fixed cold storage and significantly reduce the probability of broken-off cold chain. Although the embedding of mobile cold storage can improve the timeliness of cold chain distribution, the urban cold chain distribution with mobile cold storage becomes complicated. Specifically, mobile cold storage could play the roles of both supply and demand, which makes traditional methods difficult to describe the correlation between spatial and temporal changes in the layout of mobile cold storage and the role transition of supply and demand. This project will construct the chain structure topology of delivery routes with embedded mobile cold storage and decouple delivery routes with associated multiple trips. A chain delivery routing model is constructed. This project will explore the dynamic connection mechanism between replenishment network of mobile cold storage and distribution network of customers. A collaborative optimization method of two-level distribution service network based on dynamic connection of mobile cold storages is designed. Furthermore, this project will study the game process on resources of mobile cold storages by multiple operators on this two-level distribution service network. A cooperative optimization method of sharing and joint distribution of mobile cold storage on service network is constructed. This project will propose the theory and method of sharing and joint distribution of mobile cold storage from the perspective of short-chain. This project will be of theoretical significance and practical value to realize high-quality distribution of urban cold chain and promote the mode of the union of mobile cold storages and distribution center.
