汽车电动化发展趋势下吉利杭州湾工厂的物流创新
当前,中国汽车产业正处于由燃油车向混合动力及纯电动力代表的新能源车转型发展的过渡阶段,很多燃油车制造工厂亟需实现燃油车、混合动力车、纯电车三种类型车混线生产,这让工厂物流复杂性急剧增加。吉速物流通过打造智慧物流项目,为吉利杭州湾工厂燃油车和新能源车混线生产打下基础,实现工厂物流的增效降本,值得行业借鉴。
前言
电动化与智能化是当今汽车技术革新的主要驱动力,正在引领汽车产业生态蜕变和进化,整个行业处在技术转型过渡期,由以汽油车为代表的传统汽车逐步向以混合动力及纯电动力代表的新能源车转变。不过,汽车完全转向电动化还需一段时间,在这个过渡阶段中,越来越多的汽车制造工厂需要实现燃油车、混合动力车、纯电车三种类型车同时生产。
燃油车、混合动力车、纯电车,不同类型车辆的装配工艺不同,对工厂物流需求也会有差异,制造工厂端的物流复杂性正在急剧增加。例如,传统汽车工厂生产线是以燃油车为基础设计的,有汽油发动机分装线,纯电车则没有汽油发动机分装线,但是需要驱动电机安装工位和动力电池安装工位,而混合动力车则更加复杂,同时有发动机、驱动电机、动力电池三大安装工位,生产物流则要同时满足不同车型的各类物料需求。同时,驱动电机及动力电池体积相对较大,特别是纯电车动力电池,每个包装单元只有一个电池,现代化的汽车生产线生产速度能够达到60JPH以上,也就是大约每分钟会消耗一个电池,这就对物流效率提出极高要求;此外,多类车型共线生产,新电池底盘一体化技术引入和发展,也进一步增加了物流复杂性,急需智慧物流来解决现有难题。
一、杭州湾工厂物流升级背景
作为吉利的高产工厂之一,吉利杭州湾工厂也遇到了以上各类难题。目前,吉利杭州湾工厂内生产两种燃油车车型,生产节拍为53JPH,计划在2023年导入两种新能源车型,届时一座工厂的物流需要同时满足燃油车和新能源的四种车型混线生产的物料供应,并确保物料上线的准确性与及时性。这对传统精益生产程度已达极限的杭州湾工厂来说,存在巨大挑战。
作为吉利供应链与物流升级的重要推手,浙江吉速物流有限公司(以下简称“吉速物流”)深知智慧物流可实现物流各环节精细化、动态化、可视化管理,提高物流系统智能化分析决策和自动化操作执行能力,提升物流运作效率,是建设现代物流体系的必然之路,更是应对燃油车和新能源车混线生产的重要实现手段。
为此,吉速物流结合杭州湾工厂未来物流需求,借助现代化物流技术对工厂物流规划和运作进行改善,提高物流作业效率,改善工作环境,降低工作强度,实现减员增效的目标,更为燃油车与新能源车的混线生产打下了重要基础。
二、智慧物流项目建设
1.小件货到人
传统燃油车RDC车间(厂内物流分拨中心)的厂内小件物料上线方式为人工随车拣选,采用人工+牵引车的方式将物料配送至生产线边,工作强度大,效率不高,且存在一定的安全风险;人工拣选的模式对员工熟练程度要求较高,时常发生员工错拣、漏拣等情况,影响汽车的正常生产与品质保证。
AGV小车在产品制造过程中,既可作为无人自动搬运车辆使用,又能根据生产工艺的变化,实现多款车型混编流动生产,可大大提升汽车制造过程的物料信息化、柔性化、智能化水平。对于追求效率与品质的吉利汽车生产工厂而言,无疑是极佳的物流解决方案。
吉利杭州湾工厂引入40台360AGV(一种二维码导航AGV)小车实现了RDC车间的小件“货到人”,通过“货到人”模式对物料进行拣选,物料由360AGV小车背负货架运送至固定的拣选工作台边上,员工在工作台边进行拣选工作。总的来看,主要有以下三个方面价值:
(1)高效“货到人”拣选工作站每小时可以大约完成200订单行,是传统人工拣选效率的2倍。这对于大型主机厂动辄数十人的拣选队伍来说,无疑具有巨大优势。同时,在无人仓拆零拣选作业中,当需要拆零的货物数量占整托货物的比例达到一定程度(如90%),系统会提示拣货员做反向拣选。该模式下,拣货员将多余的货物拣出放入反向拣选缓存筐中,系统将余下的托盘货物视为整托出货,按照整托出货的流程通过机器人送往拣货区,从而大幅提高制造场景下的出库拣选效率。
(2)“货到人”拣选可以大幅度减少员工走动与搬运工作量。采用“货到人”拣选技术后,原有纯手工作业转变成系统规范操作,同时实现了数据的实时采集,实时了解现场生产状态、物流状态,对于异常情况提前进行预警和处理;系统能通过历史数据进行分析,自动进行零件冷热状态判断,将常用零件放在出口附近区域,不常用零件放在远区域,减少搬运距离,提高设备有效开动率;同时根据生产订单,提前准备相应零件,提高物流效率,也大大降低了操作者的劳动强度。此外,“货到人”拣选系统还具有安全存储、快速存储等诸多优势,是传统模式所不可比拟的,真正体现“以人为本”的物流设计理念。
(3)提高账务准确性。“货到人”拣选系统具有非常高的准确性,而传统人工小件拣选时常发生错拣、漏拣等情况,对员工的熟练度具有较高要求。采“货到人”系统后,由吉利自研GLES系统下发拉动,GLES与供应商IWMS实现系统对接,使拣选准确率达到100%,进而从根本上去掉复核环节,进一步减少工作量。
小件“货到人”打破了传统的人工拣货模式,提升了拣选效率、降低了劳动强度。同时,通过自主移动机器人也实现了自动化拣选的准确性与配送的及时性,实现物流系统的高效集成。
2.焊装车间零件无人化智能配送
吉利杭州湾焊装工厂通过引入160台360AGV,实现了焊装车间266类外协零件(含工位间转运)与42类自制零部件以及所有小零件的无人化配送,实现焊装车间全流程的AGV配送场景。线边员工通过操作呼叫器,AGV能准确地将线边所需物料配送至生产线边,彻底改变焊装车间传统的“人工+牵引车”物流配送模式。主要具有以下几方面价值:
(1)改善焊装车间物流管理。传统焊装车间物料配送由“员工+牵引车”配送上线,生产线边物料摆放混乱、物料找寻极不方便,通过360AGV智能配送物料上线,货物的摆放更加有序、整齐和规范;同时,360AGV智能配送物料上线,还能更有效地利用物流仓储面积,提高车间整洁度。
(2)优化物流规划流程。按照目前的白车身工业发展趋势,一般新车型投产一年后就要小改动一次,三年或五年后就要大改或更新换代一次,如果不进行必要的更新换代,车企在竞争激烈的当下很容易被市场所淘汰。考虑使用面积、效率、车型迭代等综合效益,同时兼顾白车身生产的柔性化,线边布局尤为关键,尤其是杭州湾工厂焊装线的线边布局十分紧张。通过360AGV的智能化配送,不仅实现了各车型生产所需零件的自动化上线,简化了车身换代过程中的物流规划流程,更减少了焊装线边面积,为焊装产线规划提供了便利。
(3)改善工作环境。机器人焊装作业产生的烟尘、电光辐射等,会对员工身体造成较大伤害。360AGV在焊装车间的智能搬运,不仅减少了现场员工物流配送,同时大大提高了现场运行的稳定性,提高工作生产的安全性。
吉利杭州湾工厂充分利用了智能AGV设备,结合吉利的GLES系统、GIDP、MES、海康的IWMS、RCS系统的有机融合,进一步提升车间自动化程度,通过系统间的无缝对接,使车间生产和仓库供料节拍更加高效、协调、流畅。
三、物流项目创新点
1.服务模式创新
吉利杭州湾工厂的智慧物流项目采用数字化技术和工厂生产相融合的模式,融合了信息管理、智能监控终端平台等技术。这不是一项单纯的技术升级,而是一种企业能力再造的过程,如何围绕客户需求建立以客户为中心的服务能力和服务体系,通过“数字+”的方式实现服务模式、运营模式和成本变化,制定针对性的方案解决策略:
(1)兼容多种协议开发,可支持REST、SOAP、TCP等系统对接协议。外接多种借口协议,将I/O信号、RS232串口、RS485等转换成可直接通讯的网口信号。
(2)机器人监控客户端可用于监控移动机器人及其任务执行状态,包含运行控制、控制干预、告警、任务监控等功能模块,方便设备维护人员及时发现设备和任务异常,主动干预,保障物流业务运行。
(3)对于业务不同场地情况,AGV采用二维码、SLAM等导航模式。二维码导航通过控制二维码传感器的扫描获取到地面铺设的二维码图像坐标系中的位置,把采集到的二维码图像的位置坐标信息传送给AGV控制器,通过控制器计算图像传感器提供的坐标数据,确定图像在地图上的位置,继而通过调度系统将指令发送给AGV小车。
2.开发模式创新
对于一个非常复杂的系统,一般都采用迭代式的开发模式,重复的实施可能需要相当大的成本。在项目正式启动前,完成一个系统的仿真来降低项目风险是非常有必要的。利用现有设备参数、传感器、AGV运行历史数据等,集成场景、生产节拍、多概率的仿真,在虚拟空间中完成映射,从而反映相对应设备运行。
3.生产模式创新
打破传统人工拣配物料的方式,采用AGV智能配送,实现从“人找货”到“货到人”的模式创新,解决了找货难、找货时间长、货物盘点复杂等传统问题,加之立体库、无人叉车、无人仓等现代物流设备技术,实现了机器换人,提高效率,降低对人员素质的要求,同时AGV任务的可视化、统计信息可视化、报警信息可视化,做到了生产的过程监控,减少差错率,提升人效,并提高生产质量。
四、取得的效益与未来推广
吉利杭州湾工厂智慧物流项目的成功落地,为新能源车型与燃油车混线生产下的物流高效运作提供了保障,并在物流降本增效方面效益明显。
吉利杭州湾工厂智慧物流项目小件“货到人”2022年11月正式上线运行,焊装无人化智能配送2023年6月正式上线运行,项目整体运行接近一年,已累计为吉利杭州湾工厂节省66名一线物流作业人员,其中“货到人”模式更人性化减少了95%的无效行走,降低了员工工作强度,实现全面的自动化、信息化、智能化,让企业人员从简单重复的劳动中解放出来,去从事更有价值的工作;系统软件协同联动、数据互通,真正做到智能运维、实时反馈,让生产运营管理水平进一步提升,提高了整体的工作效率和准确率;面对新车型的导入、产能的提升等都可以通过动态库存布置、智能系统负载均衡来轻松应对,节省了大量的重复规划工作。
吉利杭州湾工厂智慧物流项目的整体投资回收期小于2年,后续将在吉利集团各个生产工厂陆续铺开推广,预计在2023年底可以为吉利汽车集团减少近百人物料配送员工,减少近百台牵引车的使用,同时可以有效避免工厂安全事故的发生,实打实地提高企业的利润与综合竞争力,同时应用大量的数字化管理技术,有效实现物流的智能调度管理、优化业务流程,加强物流管理的合理化,降低物流消耗。
智慧物流依托于信息的传递与共享实现配送效率的提升,但物流信息标准化推进的迟滞使得信息难以迅速得到充分利用,从而影响智慧物流发挥降本提速的作用,同时其对配送效率的改进效果也不尽如人意。尽管智慧物流为物流企业发展带来了光明未来,但智慧化建设需要大量技术、人力和资本的投入,使得中小企业踌躇不决。吉利杭州湾工厂智慧物流项目的成功落地,颠覆了吉利汽车集团乃至整个汽车行业的物流拣配方式,使其他主机厂纷纷效仿。

Logistics innovation of Geely Hangzhou Bay Plant under the development trend of automobile electrification
At present, China’s automobile industry is in the transition stage of transformation and development from fuel-powered vehicles to new energy vehicles represented by hybrid and pure electric power. Many fuel-powered vehicle manufacturing factories are in urgent need of hybrid production of fuel-powered vehicles, hybrid vehicles and pure tram vehicles, which dramatically increases the complexity of factory logistics. By building smart logistics projects, Jisu Material Circulation has laid a foundation for the hybrid production of fuel vehicles and new energy vehicles in Geely Hangzhou Bay Factory, and achieved increased efficiency and cost reduction of factory logistics, which is worthy of reference for the industry.
Preface
Electrification and intellectualization are the main driving forces of today’s automobile technological innovation, which are leading the ecological transformation and evolution of the automobile industry. The whole industry is in the transition period of technological transformation, from the traditional automobile represented by gasoline cars to the new energy vehicles represented by hybrid and pure electric power. However, it will be some time before cars are fully electrified, and more and more plants will need to make all three types of cars at the same time, including gas-powered cars, hybrids and pure electric cars.
The assembly process of different types of vehicles
The assembly process of different types of vehicles, such as fuel vehicles, hybrid vehicles and pure trams, is different, and the demand for factory logistics is also different. The complexity of logistics at the manufacturing plant is increasing sharply. For example, the production line of traditional automobile factory is designed on the basis of fuel vehicle, with gasoline engine assembly line, while pure electric car does not have gasoline engine assembly line, but it needs driving motor installation stations and power battery installation stations. However, hybrid electric car is more complicated, with three installation stations of engine, driving motor and power battery.
Production logistics to meet the needs of different types of materials at the same time. At the same time, the volume of the driving motor and the power battery is relatively large, especially the pure trolley power battery. Each packaging unit has only one battery. The production speed of modern automobile production line can reach more than 60JPH, that is, one battery will be consumed every minute, which puts forward extremely high requirements for logistics efficiency. In addition, the common production of multiple vehicle types and the introduction and development of new battery chassis integration technology also further increase the complexity of logistics, and it is urgent to solve the existing problems of intelligent logistics.
Background of logistics upgrading of Hangzhou Bay Factory
As one of Geely’s high-yield factories, Geely Hangzhou Bay Plant has also encountered all kinds of problems above. At present, Geely Hangzhou Bay plant produces two fuel vehicle models with a production time of 53JPH. It is planned to introduce two new energy models in 2023. At that time, the logistics of one plant needs to meet the material supply of the mixed production of fuel vehicle and four new energy models at the same time, and ensure the accuracy and timeliness of material on-line. This is a huge challenge for Hangzhou Bay factory, which has reached the limit of traditional lean production.
As an important driver of Geely’s supply chain and logistics upgrading, Zhejiang Jisu Logistics Co., LTD. (hereinafter referred to as “Jisu Logistics”) knows that intelligent logistics can realize the fine, dynamic and visual management of each link of logistics, improve the logistics system’s intelligent analysis, decision-making and automatic operation and execution ability, and improve the efficiency of logistics operation, which is the inevitable way to build a modern logistics system. It is an important means to realize the mixed production of fuel vehicles and new energy vehicles.
Therefore, Jisu Logistics combined with the future logistics needs of Hangzhou Bay factory, with the help of modern logistics technology to improve the logistics planning and operation of the factory, improve logistics efficiency, improve the working environment, reduce work intensity, achieve the goal of reducing staff and increasing efficiency, and lay an important foundation for the mixed line production of fuel vehicles and new energy vehicles.
Construction of smart logistics projects
Small goods arrive
In the traditional fuel truck RDC workshop (in-plant logistics distribution center), the on-line way of small parts materials in the plant is manual selection, and the way of manual + tractor is used to distribute materials to the production line. The work intensity is high, the efficiency is not high, and there are certain safety risks. Manual picking mode has high requirements on the proficiency of employees, and often occurs wrong picking and missing picking, which affects the normal production and quality assurance of vehicles.
In the process of product manufacturing, AGV car can not only be used as an unmanned automatic handling vehicle, but also according to the changes of production technology, realize the mixed flow production of multiple models, which can greatly improve the information, flexibility and intelligent level of materials in the automobile manufacturing process. It is undoubtedly an excellent logistics solution for the Geely Auto production plant that pursues efficiency and quality.
Geely Hangzhou Bay Factory introduced 40 sets of 360AGV (a two-dimensional code navigation AGV) cars to realize the small parts of the RDC workshop “goods to people”, through the “goods to people” mode of material selection, materials from the 360AGV car carrying shelves to the edge of the fixed selection workbench, employees in the workbench side for selection.
In general, there are mainly three aspects of value:
(1) Efficient “goods to people” sorting workstation can complete approximately 200 order lines per hour, twice the efficiency of traditional manual sorting.
This is no doubt a huge advantage for the selection team of dozens of large OEM. At the same time, in unattended warehouse dismantling and picking operation, when the number of goods to be dismantled accounts for a certain percentage of the total goods (such as 90%), the system will prompt the picker to do reverse sorting. In this mode, the picker will pick out the excess goods and put them into the reverse picking cache basket, and the system will regard the remaining pallets of goods as bulk delivery, which will be sent to the picking area by robot according to the process of bulk delivery, thus greatly improving the efficiency of warehouse picking under the manufacturing scenario.
(2) “goods on arrival” selection can greatly reduce the staff movement and handling workload.
After adopting the “goods to people” picking technology, the original pure manual operation has been transformed into the system standard operation. At the same time, the real-time collection of data has been realized, the real-time understanding of the field production status and logistics status, and the abnormal situation has been warned and dealt with in advance. The system can analyze the historical data and automatically judge the cold and hot state of the parts.
The common parts are placed in the area near the exit and the less common parts are placed in the far area to reduce the handling distance and improve the effective operating rate of the equipment. At the same time, according to the production order, prepare the corresponding parts in advance, improve the logistics efficiency, but also greatly reduce the labor intensity of the operator. In addition, “goods to people” selection system also has many advantages, such as safe storage, fast storage and so on, is incomparable to the traditional mode, truly reflects the “people-oriented” logistics design concept.
(3) Improve accounting accuracy.
The “goods to people” picking system has very high accuracy, but the traditional manual small parts picking often happens wrong picking, missing picking, etc., which has high requirements for the proficiency of employees. After the “goods to people” system is adopted, Geely’s self-developed GLES system delivers pull, and GLES implements system docking with supplier IWMS, enabling the picking accuracy to reach 100%, thus fundamentally removing the review link and further reducing the workload.
“Goods to people” breaks the traditional manual sorting mode, improves the sorting efficiency and reduces the labor intensity. At the same time, the accuracy of automatic selection and the timeliness of distribution are also realized through autonomous mobile robots, and the efficient integration of logistics system is realized.
Unmanned intelligent distribution of welding workshop parts
By introducing 160 sets of 360AGVs, Geely Hangzhou Bay Welding Factory has realized the unmanned distribution of 266 types of outsourced parts (including inter-station transfer), 42 types of homemade parts and all small parts in the welding workshop, realizing the AGV distribution scene of the whole process in the welding workshop. By operating the call, the AGV can accurately distribute the materials required by the wire edge to the production line, completely changing the traditional “manual + tractor” logistics distribution mode of welding workshop. It mainly has the following values:
(1) Improve the welding workshop logistics management.
The traditional welding workshop material distribution by “staff + tractor” distribution online, the production line side of the material placement is chaotic, material search is very inconvenient, through 360AGV intelligent distribution material online, the placement of goods is more orderly, neat and standard; At the same time, 360AGV intelligent distribution materials online, but also more effective use of logistics storage area, improve workshop cleanliness.
(2) Optimize the logistics planning process.
According to the current development trend of the body-in-white industry, generally a new model will have a small change after one year of production, and a major change or replacement after three or five years. If necessary replacement is not carried out, car enterprises are easily eliminated by the market in the current fierce competition. Considering the use area, efficiency, model iteration and other comprehensive benefits, while taking into account the flexibility of body in white production, line-edge layout is particularly critical, especially the line-edge layout of welding line in Hangzhou Bay factory is very tight. Through the intelligent distribution of 360AGV, it not only realizes the automatic online of the parts required for the production of various models, simplifies the logistics planning process in the process of body replacement, but also reduces the welding line edge area, providing convenience for the welding production line planning.
(3) Improve the working environment.
Robot welding operation generated soot, electro-optical radiation, etc., will cause great harm to the staff’s body. The intelligent handling of 360AGV in the welding workshop not only reduces the logistics distribution of on-site employees. But also greatly improves the stability of on-site operation and the safety of work production.
Geely Hangzhou Bay Factory has made full use of intelligent AGV equipment, combined with the organic integration of Geely’s GLES system, GIDP, MES, Haikang’s IWMS and RCS systems, to further improve the degree of automation of the workshop. Through the seamless connection between the systems. The workshop production and warehouse material supply beats are more efficient, coordinated and smooth.
Logistics project innovation point
Service model innovation
The smart logistics project of Geely Hangzhou Bay Factory adopts the mode of integrating digital technology and factory production. Integrating information management, intelligent monitoring terminal platform and other technologies. This is not a simple technology upgrade. But a process of enterprise capability reconstruction. How to build customer-centered service capability and service system around customer needs. Through the “digital +” way to achieve the change of service mode, operation mode and cost, formulate targeted solutions:
(1) Compatible with a variety of protocols, supporting REST, SOAP, TCP and other system interconnection protocols. A variety of excuse protocols are connected to convert I/O signals, RS232 serial ports, RS485 ports, etc. Into port signals for direct communication.
(2) The robot monitoring client can be used to monitor the mobile robot and its task execution status. Including operation control, control intervention, alarm, task monitoring and other functional modules. Which is convenient for equipment maintenance personnel to find equipment and task anomalies in time, take the initiative to intervene. And ensure the operation of logistics business.
(3) For different business sites, AGV adopts navigation modes such as QR code and SLAM. Two-dimensional code navigation obtains the position in the two-dimensional code image coordinate system laid on the ground by controlling the scanning of two-dimensional code sensor. And transmits the position coordinate information of the two-dimensional code image collected to the AGV controller. The controller calculates the coordinate data provided by the image sensor, determines the position of the image on the map. And then sends the instruction to the AGV vehicle through the dispatching system.
Development mode innovation
For a very complex system, iterative development is generally adopted, and repeated implementation may require considerable cost. Before the formal start of the project. Ut is necessary to complete a system simulation to reduce the risk of the project. By using the existing equipment parameters, sensors, AGV operation history data, etc.. The simulation of scene, production beat and multi-probability is integrated. And the mapping is completed in the virtual space, so as to reflect the operation of corresponding equipment.
Innovation of production mode
It breaks the traditional way of manual material sorting and distribution, adopts AGV intelligent distribution. Realizes the mode innovation from “people looking for goods” to “goods to people”. Solves the traditional problems such as difficult to find goods. Long time to find goods, complicated cargo inventory, and so on. Combined with the modern logistics equipment technology such as three-dimensional warehouse, unmanned forklift truck, unmanned warehouse, realizes machine replacement, improves efficiency. And reduces the requirements on personnel quality. At the same time, the visualization of AGV task, statistical information and alarm information can monitor the production process. Reduce the error rate, improve human efficiency and improve the production quality.
Benefits achieved and future promotion
The successful implementation of the smart logistics project in Geely Hangzhou Bay Factory has provided a guarantee for the efficient operation of logistics under the hybrid production of new energy models and fuel vehicles. And has achieved significant benefits in terms of cost reduction and efficiency increase in logistics.
Geely Hangzhou Bay Factory smart logistics project small pieces “goods to people” officially launched in November 2022, welding unmanned intelligent distribution officially launched in June 2023. The overall operation of the project has been nearly a year, has saved a total of 66 first-line logistics operators for Geely Hangzhou Bay Factory. Among which the “goods to people” mode is more humane, reducing 95% of invalid walking.
Reduce the work intensity of employees, achieve comprehensive automation, information, intelligent. So that enterprise personnel from the simple and repetitive labor liberation, to engage in more valuable work. System software collaboration, data interworking, truly intelligent operation and maintenance, real-time feedback. So that the production and operation management level is further improved, improve the overall work efficiency and accuracy. In the face of the introduction of new models, production capacity can be improved by dynamic inventory layout. Intelligent system load balancing to easily cope with, save a lot of repetitive planning work.
The overall payback period of the smart logistics project of Geely Hangzhou Bay Factory is less than 2 years
The overall payback period of the smart logistics project of Geely Hangzhou Bay Factory is less than 2 years. And it will be rolled out and promoted in various production factories of Geely Group successively. It is estimated that by the end of 2023. It can reduce nearly 100 material distribution employees and the use of nearly 100 tractors for Geely Auto Group. And effectively avoid the occurrence of factory safety accidents. Effectively improve the profit and comprehensive competitiveness of the enterprise. At the same time, the application of a large number of digital management technology. Effectively realize the intelligent logistics scheduling management, optimize the business process, strengthen the rationalization of logistics management, reduce logistics consumption.
Intelligent logistics relies on the transmission and sharing of information to improve the distribution efficiency. However, the delayed promotion of the standardization of logistics information makes it difficult to make full use of the information quickly. Which affects the role of intelligent logistics in cost reduction and speed increase. Meanwhile, its improvement effect on the distribution efficiency is not satisfactory. Although smart logistics has brought a bright future for the development of logistics enterprises. Smart construction needs a lot of technology, manpower and capital investment, which makes small and medium-sized enterprises hesitate. The successful landing of the smart logistics project in Geely Hangzhou Bay Plant has subverted the logistics sorting method of Geely Auto Group and even the entire automobile industry, making other Oems follow suit.
