Research On Manufacture Procedure Improvement Of A Company's Type B Metro

As an important means of transportation,subway has the characteristics of large capacity,fast speed and high punctuality compared with traditional bus,which can greatly relieve the pressure of public transportation.Therefore,with the development of China's economy and the acceleration of urbanization,more and more cities have incorporated subway into the construction of urban infrastructure.The construction of subway brings opportunities for the development of a large number of domestic enterprises engaged in the manufacturing of rail transit equipment.At the same time,the surge of output also makes the original process system fail to meet the existing production demand,which has become an urgent problem for the development of enterprises.A company is a large manufacturer of rail transit vehicles.Its core business is the integration of vehicles and it also encountered some problems.After sorting out relevant background and domestic and foreign research situations,this paper introduces the current situation of A company,summarizes typical problems encountered in the production integration of subway model B in A company based on the communication with relevant personnel of the company,and determines the research object of this paper.To analyze the causes of problems by fishbone diagram,through 5W1 H,ECRS and critical path methods to optimize different problems,the premise of optimization is not to affect the overall production process,through the local optimization of relevant factors,achieve to the improvement of the manufacturing process and improve the efficiency of A company assembly production.A company is a well-known enterprise in the industry,and the problems it encounters are closely related to the current overall environment.The author hopes to provide references for other companies in the industry by studying these problems and proposed relevant optimization methods.
