Research On Optimization Of Lean Production In M Company's Air Conditioning Plant

With the development of society,more and more manufacturing companies have begun to transform to intelligent manufacturing.During the transfer process,many manufacturing companies have slow or failed transformation.At the beginning of the transformation,M Company tried to rapidly transform and upgrade to the level of intelligent manufacturing by directly investing in automation equipment and production lines.However,due to insufficient analysis of product demand and insufficient flexible design of the wire body,the project failed.After summing up and reflecting on the project,it was concluded that the market demand fluctuated frequently,the flexible design of the production line was insufficient,the production and type change was slow,the automation equipment was heavy and bulky,and it was impossible to quickly adjust the layout of the equipment.This article attempts to combine M company's transformation case as a research background to discuss how to optimize lean production in manufacturing companies.the problems faced by traditional manufacturing companies when they begin to transform are: determination of the direction and objectives of the transformation,how to transform,and how to evaluate the transformation results.This article takes M company's air conditioner production as a case study.By taking the customer's order demand as the main axis,the direction of transformation is discussed.Analyze the existing business process,find the difference with the goal,and seek reform measures.Using lean production knowledge and tools,through the use of value stream tool analysis,planning for the future vision of manufacturing companies,and formulating corporate strategic guidelines.Implement tools such as standardized operations,rapid model changes,and lean logistics for analysis,and study how to gradually carry out the reform of lean chemical plants.By establishing an evaluation model of lean maturity,quantitative evaluation and improvement of the effect of lean implementation are made.The significance of this paper: the establishment of a model for evaluating the maturity of lean chemical plants in manufacturing companies represented by air conditioners.For the first time,from the perspective of quantification,combined with lean production knowledge system,value stream analysis,standardization work promotion,and lean logistics design tools,Promoting the reform process of traditional manufacturing enterprises to lean chemical plants,laying a theoretical foundation and practical guidance methods.
