Research On Automobile Parts Inbound Logistics Mode Of Fusing Milk-run And Drop With Pull Transport

The increasing sales volume of automobiles has brought opportunities to the automobile manufacturing industry,but it also has brought enormous challenges to the Automobile Parts Inbound Logistics.With the rise of “ lean production” and “just-in-time production”,the traditional Automobile Parts Inbound Logistics mode meets the needs of low inventory and parts in the warehouse time reduction,which inevitably leads to a sharp increase in transportation costs.Therefore,how to introduce new transportation modes,new energy technology applications,new vehicle use,etc.to optimize the Automobile Parts Inbound Logistics is a question worthy of consideration.Comprehensive analysis of foreign advanced Automobile Parts Inbound Logistics cases,found that the use of Milk-run mode can reduce transportation costs and improve the efficiency of the supply chain.As a new type of transportation--Drop and Pull transport,it has the advantages of increasing mileage rate,reducing waiting time for laytime and reducing environmental pollution,and has been promoted at domestic and abroad.Considering that LNG vehicles have good economic and social benefits,this paper tries to mix Milk-run、Drop and Pull transport and LNG vehicles together,break through the limitations of the Automobile Parts Inbound Logistics model,and establish a new low-carbon,high-efficiency Automobile Parts Inbound Logistics model.Based on the above analysis,this paper firstly demonstrates the feasibility of Drop and Pull transport and LNG vehicle use from many aspects.At the same time,taking Anji Logistics as an example,on the basis of in-depth analysis of the current situation of its Inbound Logistics,a two-stage mathematical model integrating Milk-run and Drop and Pull transport is established.Then,the suppliers of Anji Logistics are classified in detail,and the mathematical model is solved by using the genetic algorithm,which is programmed by the software of Matlab.By comparing and analyzing the mileage,energy consumption and transportation efficiency with the traditional Inbound Logistics mode,it is found that the mileage saving rate is as high as 82%,the energy consumption of LNG vehicles is reduced by about 30% compared with diesel,and the utilization rate of vehicles and transportation efficiency has been improved.Secondly,the Activity Based Classification and systematic layout planning are applied to optimize the warehouse layout of the Cross-docking mode.The combination of direct transportation and recycling is proposed and using intelligent cross-docking distribution management system to optimize the Cross-docking under the Milk-run mode.Thirdly,in order to improve the efficiency of logistics operation,this paper levelled the logistics of automotive parts from the order demand,parts collection and the host plant’s acceptance.Finally,the status quo of information management of Anji Logistics material box rack is analyzed in detail.On this basis,this paper analyzed the types and distribution characteristics of automotive parts,and established the RFID coding system,developed a material box rack management system,and established the functional architecture of the full lifecycle assembly unit management system of RFID technology.
