Value Stream Mapping Improvement Research Of Air Cleaner Manufacturing In Y Company

At present,our social economy has entered a new era of pursuing higher quality development.Correspondingly,for the manufacturing industry,how to improve efficiency,reduce costs and provide higher quality products and services in the era is an important topic many enterprises faced.For the automobile and supporting parts manufacturing industry,which occupies an important part in the national economy,the production organization of many parts enterprises at the present stage is still dominated by the push model based on customer information prediction.This model seems to have greater flexibility,but its actual disadvantages are also obvious:Subjective prediction cannot replace objective market demand,and the inconsistency between subjective and objective results in a large amount of waste of product cost,which is not conducive to timely and accurate product delivery of customers.This kind of waste did not have a great impact in the initial stage of the vigorous development of the automobile industry before.The rapid and extensive growth covered up the waste of a large number of inefficient and low-quality resources.With the changes of the market and the new market competition situation,it has been unable to meet the development needs of the new era in which the stock competition is becoming fierce.In this context,this paper selects Y Company,an auto parts supporting enterprise,as the research object,uses value stream analysis,combines the theoretical knowledge of lean production,identifies the problems in the internal process,scientifically analyzes the causes of inefficiency and waste,and sorts out the effective optimization direction.By mainly using Kanban pull tool,the internal production process is transformed from push type to pull type.So as to improve the problems found and enhance the actual operation and management level of Y enterprise.Specifically,by studying the material flow mode and efficiency of value stream in the internal production process of auto parts Y Company,this paper first analyzes the value stream of relevant internal production process with the support of relevant theories and research data,without seeking a large number of incremental resources and without affecting product cost and quality level.Secondly,through literature research,interview and data analysis,the root cause is mined.Finally,the specific solution ideas and methods are formed.Through Kanban pulling,an important tool under the concept of pulling,the relevant weak links are adjusted,added,transformed and optimized,which reduces the internal cost waste and improves the production efficiency of internal material flow.Through the optimization of value stream element combination,Y Company has reduced the area of internal WIP products and reduced the cost of capital occupation;Through the application of Kanban,a tool that reflects customers’ actual needs,Y company has reduced the production delivery time that accurately responds to customers’ order demands,reduce raw material stock and time waste,improved overall material flowing efficiency,which is conducive to improving customer satisfaction.Of course,the period of management reform carried out in this paper is short,which fails to fully consider more new challenges that Y company may encounter in the future.The final effect of value stream enhancement also needs to be further tested.The value research results of this paper can not only help to improve the actual operation results of Y company,enhance the lean improvement culture atmosphere of Y Company and improve the management quality of employees,but also provide possible solutions for auto parts enterprises which are facing similar problems.
