Research On Simulation And Optimization Of Production Logistics Of Wheel Motor Of Company B

Production logistics is a crucial aspect of enterprise production.Balanced and stable production logistics can ensure smooth circulation of in-process inventory and shorten the production cycle.This paper conducts in-depth on-site inspections of electric two-wheeled vehicle wheel hub motor enterprises,analyzes the main problems in production logistics based on enterprise operations,optimizes logistics volume,logistics equipment,and production line balance based on production processes,production capacity,and production cycle;this is favorable for improving the production efficiency of wheel hub motor production enterprises,enhancing their competitiveness,promoting the deepening of the lightweight travel lifestyle,and advancing the development of the "dual carbon" initiative.Firstly,this paper analyzes the actual survey situation and focuses on the overview of production logistics at Company B,including the production process of wheel hub motors,logistics equipment,and production capacity.Then,it summarizes and analyzes the existing problems of in-process inventory backlog,loading and unloading handling,and on-site production management in the production logistics system.Secondly,using Flexsim to simulate the wheel hub motor production logistics system,it analyzes the busy rate of the assembly line workstations,the backlog of the semi-finished products in the line package,and the handling tool load after running the model for 16 hours.With the combination of research,it draws a fishbone diagram to organize key factors for improvement.Finally,based on the previous analysis,the assembly line operation distribution is adjusted using the ECRS principle,and the 0-1 programming is used to determine the minimum cycle time of the assembly line.The optimized assembly line balance rate increases from 45.81% to 83.23%,and the bottleneck operation time decreases from 36.38 seconds to 26.48 seconds.Running the optimized Flexsim simulation model shows that the semi-finished product backlog is reduced from 4130 pieces to 1286 pieces,significantly improving the backlog of work-inprocess.At the same time,a dedicated handling tool is designed for the characteristics of wheel hub motor materials,which increases the loading capacity by 150% while avoiding cargo damage.Running the optimized Flexsim simulation model shows that the walking distance of two handling personnel is reduced from 10328.71 meters and 10648.07 meters to8162.18 meters and 8539.04 meters,effectively reducing their workload.In addition,in order to ensure the smooth implementation of production logistics optimization measures and the continuous improvement of the enterprise,lean management tools such as 5S management,standardized operations,and visual management are used to improve the production workshop management system.The results demonstrate that the research framework and methodology of this paper are reasonable and effective,which serves as a useful reference for other wheel hub motor production enterprises to carry out lean improvement of their production logistics systems based on their own production practices.Furthermore,it has significance for traditional manufacturing enterprises to transform and upgrade their operations.
