The Research Of Factory Design And Layout Of Machining Workshop Of H Company Based On Lean Production

In recent years,As global economic growth continues to decline,Due to the continuous decline of global economic growth,especially the global economic growth index published by the International Monetary Fund in recent two years,it is the lowest level since the international financial crisis.In the context of the global economic downturn,the global shipping market continues to be depressed,and the sustained low-speed growth of global economy and shipping market demand will become the new normal.Facing the severe market situation and management dilemma,shipbuilding industry is re examining.Find a new and different way of survival and development in the long market downturn.H company is the largest R & D manufacturer of marine high power fuel injection system in China,It also faces the problems of how to optimize the production process,shorten the production cycle,improve the quality and efficiency,and improve the competitiveness of products under the increasing market pressure.In the process of development,lean management is paid more and more attention by enterprises.Factory layout is one of the important aspects.Reasonable factory layout can not only reduce the cost of product manufacturing and operation,but also improve the efficiency of production,logistics and equipment utilization as well as the quantity of qualified products.At the same time,the lean concept is integrated into the system layout design.It can optimize the production management process of the whole enterprise,improve the overall economic benefits of the enterprise,and make the enterprise have higher competitiveness.In this paper,lean thinking and systematic planning and design layout as the theme.The purpose is to make a more in-depth description of the whole process of layout design through the application research of H company’s machining workshop layout.Introduce lean thinking and systematic facility layout with examples,It also provides inspiration and reference for many enterprises that have not yet imported lean ideas,plan to import lean ideas or are in the process of importing them.Furthermore,it plays a certain role in promoting the further popularization of lean production in domestic manufacturing enterprises with multiple varieties and small batch product structure.Inside,this paper first introduces lean thinking and SLP and other basic theoretical tools.Optimize the facility layout in the machining workshop of H company through SLP,and introduce the case study and the whole process of building local lean unit production line.The idea and tools of layout design are expounded systematically.And focus on lean thinking and systematic facility layout planning theory and method,highlighting the practical application of theoretical tools.At the end of the case study,the optimal scheme is obtained by comparing the quantitative and non quantitative indexes.The power of lean idea is demonstrated by the improvement and application results of local lean unit production line.It also points out the characteristics of the combination of various tools and concepts in lean system.Finally,this paper summarizes the steps of layout optimization.The advantages and limitations of optimization and improvement are briefly analyzed.Suggestions on the way of "intelligent factory" from the perspectives of personnel,plan and enterprise vision.Emphasize the importance of lean thinking theory to promote the continuous improvement of the company.Pointed out the direction for the future promotion of the company.
