| The manufacturing industry is the foundation of the national economy,the "ballast" for the country to ensure economic development,the foundation for building a country,the tool for strengthening the country,and the indispensable industry for promoting economic and social growth and improving the quality of people’s employment.However,the current international situation is chaotic and complex,and the global economy is facing unprecedented major changes.China’s manufacturing industry is facing increasingly fierce market competition.China’s manufacturing industry has been unable to get rid of the development path of relying on cheap labor,and has been unable to break the situation of large but not strong.How to reasonably reduce production and operation costs and improve production efficiency has become an urgent problem for manufacturing enterprises in China.Q Company is a well-known manufacturing enterprise in China,which also suffers from the problems of manufacturing enterprises in China.At the same time,enterprises need to improve in manufacturing cost,delivery cycle,production line flexibility,aftersales service quality and other dimensions.Lean production is a relatively mature and widely accepted enterprise management and operation mode by advanced manufacturing enterprises.It has made remarkable achievements in improving the efficiency of enterprise production and manufacturing and improving the competitiveness of the company in the same industry.This paper analyzes the assembly line of A product of Q company through on-site investigation and analysis of the workshop of Q company,combining with the questionnaire survey method and using the lean production method,combs the production process flow of the assembly line,collects the relevant process data through the operation measurement,and calculates the balance rate and production schedule,thus exposing many problems in the assembly line and on-site management of the product workshop;Then,the existing problems are classified and sorted out,and the causes of the problems are analyzed.In the follow-up optimization plan,based on the principle of lean thinking,the 6S on-site management method is used to propose suggestions on the standardization of on-site management;Using the "5W1H","ECRS" principles and process analysis methods,the project design of improving the balance rate of the assembly line and optimizing the process was carried out;Relevant lifting methods are proposed for the stability of equipment operation;Then specific measures are formulated for the problems existing on site to ensure the effective implementation of the improvement method;After that,we will continue to improve the corporate culture,strengthen the training related to lean production,and develop a standardized system to ensure the implementation of the optimization plan,so that the concept of lean production can penetrate into every employee’s heart and promote the healthy development of the company. |
