Progress Management Optimization Of Automotive Splined Yoke Research And Development Project Based On Key Chain Technology

With the development of the global economy,the automobile market has doubled in magnitude,and major auto manufacturers have invested more in research and development of new technologies and new products to seize the market,improve competitiveness,and meet the growing diversified needs of the world market.However,a lot of manpower,material resources and time are required in the development of new automotive products,and project schedule management in the automotive industry came into being.In the face of more and more complicated actual production and technological development,traditional project management methods such as work breakdown structure and Gantt chart have been difficult to meet the requirements of enterprise development strategy.Therefore,it is very important to use the key chain technology that attaches importance to resource constraints in the actual production of the automotive industry.Based on the project background,based on the theoretical basis of the project schedule management theory and the front-line interview information,this paper analyzes the current status and achievements of identifying key chains and setting buffer zones at home and abroad,and takes Nanjing Quanfeng Company's automotive spline shaft R&D project as the research object,Found problems in the current project progress management: the project uses a serial management model,and the critical path during the implementation process is ambiguous;during the project progress control process,the influence of factors such as "student syndrome" and resource conflicts is ignored;due to the industry and The particularity of the client,neglecting the key milestones of the project and ignoring the project schedule caused the waste of project safety time.After applying the key chain technology to the progress management of the automobile spline shaft R&D project,the project duration was significantly shortened,and the total project cost was reduced,which saved sufficient time for the subsequent complete machine work and exceeded the customer's expected indicators.The order opened the German market for the company.Curtain.In addition,in order to ensure that the key chain technology can be smoothly promoted during project implementation,three points of management guarantee measures are proposed: 1.Due to the shortened construction period,the overall project cost is reduced and the cost is optimized;2.The project management model is changed to a strong matrix type The project manager has the right to mobilize relevant resources within the scope of this authority;3.The company's organizational structure is project-oriented,and the project manager is responsible for the project.At this stage,in the face of global industrial automation production trends,the company's core components still use the traditional mechanical processing method of human cooperation with CNC lathes.Compared with the mature machining production lines in Germany and Japan,under the background of high automation,the production quantity of parts processed with only 4 manpower per day is equal to the quantity produced by our company with 22 manpower and 35 machine tools.Therefore,traditional machining manufacturers need to actively transform automated production lines.After the products are stable,they should slowly invest in first-line production with higher-precision automation.With the advancement of the country's strategy in Industry 4.0,along with the maturity and development of big data,artificial intelligence,3D printing and other technologies,both in mold manufacturing and process production will have a qualitative leap,and the future production line will definitely become more trendy For digital production,it will be more intelligent and precise.
