Line Balance Analysis And Improvement For M Product Of J Company

Nowadays the manufacturing industry mostly adopts the production line mode.Under the production line mode,how to improve the balance rate of the production line,improve the overall production efficiency and productivity,at the same time,reduce the production rhythm,simplify the staff and machines,and reduce the work-in-process between the processes,this has been paid more and more attention by many manufacturing enterprises,which is also the urgent problem for many manufacturing enterprises.Firstly,this paper introduces the concept of production line balance,background and research status at home and abroad.According to the theory of production line balance,this paper expounds the evaluation index of production line balance and the main factors affecting production line balance,and the related concepts of industrial engineering theory,aiming at improving the production line balance rate for M products of J Company.Secondly,in view of the three factors affecting the balance of production line: the production capacity of process and equipment,the technical level of operators and the operation content of the process,the author of this paper investigated and analyzed these three aspects on –site,collected the relevant data.Through the methods of industrial engineering: stopwatch time research,operation analysis and man-machine analysis,determined the production method,production process and the distribution of production line stations for M products of J Company.Then through the method of operation measurement,scientifically calculated the standard time of each process.Use the evaluation index of production line balance to reflect the actual operation efficiency of M the production line,then analyzed the problems of M production line balance.Thirdly,based on the analysis of the data to diagnose the problem,we targeted to put forward reasonable improvement suggestions.For example,in view of the problem that the production capacity cannot meet the customer demand,the operation analysis method is used to analyze the bottleneck station and reduce the standard working hours of the bottleneck station reasonably.To solve the problem of unreasonable allocation of man-machine,the man-machine analysis was redistributed to reduce the waiting time for the operators and improve the efficiency of equipment.For assembly time for each station is not balanced,the different stations between employees complain about each other,through the application analysis of the four principles: Eliminate,Combine,Rearrange and Simplify,optimize the production process,to redistribute work content for each station,reduce operation time differences between each station.As for other related problems,also proposed improvement plans one by one according to the actual situation,and achieved good results.The production line balance rate improved from 69.8% to 88.2%.UPH increased from 40 to 56.The evaluation index of production line balance delay was also improved from "poor" to "good".Comprehensive evaluation indicators have also increased,while also meeting the needs of customers.Finally,took the balance rate of the production line as the sustainable improvement index of M product every quarter,aiming to further improve the evaluation index of the balance delay of the production line from "good" to "excellent",so as to continuously optimize the balance of M production line.This paper provides a universal scheme to improve the balance rate of production line,summarizes the application methods of relevant industrial engineering theories and related tools in the balance improvement project of production line,and provides a good model for the balance improvement of production line of J company's other products.In addition,through the summary of this paper,the M production line employees of J Company have a deeper understanding of the indicator of the production line balance rate,which not only effectively improves the production efficiency of the company,but also leads to the thinking and prospect of the production line balance rate of other products.
