1、项目介绍

技术栈：
Python语言、Django框架、Echarts可视化、MySQL数据库、HTML、报表、物流信息、多角色登录、物流管理

这篇文章提出了一种新型的物流管理系统，旨在帮助物流公司更好地掌握和运营各种物流数据。该系统采用python和django两种常见的框架，通过MVT来实现对数据集成和分析，从而更好地满足各种需求。此外，该系统还支持多种数据访问，如订单、运输、仓储、配送、销售、服务。通过使用该客户端，我们可以轻松获取有关物流的各种详细信息，并且可以通过输入相应的物流编码来快速检索。该系统的结构紧凑，可有效地帮助物流企业实现有序的运营。
系统的测试表明，本系统可以方便快捷地实现物流管理中的货物登记、出库入库、组车运送等工作，使物流管理工作井井有条，为企业的健康发展创造良好的条件。

2、项目界面

（1）数据可视化大屏

（2）运单详情信息

（3）发货库存信息

（4）运单详情信息

（4）用户权限管理
