Research On Lean Production Management In Pipe Processing Workshop Of Shipbuilding Enterprises

The biggest problem facing shipbuilding companies is how to reduce construction costs and increase production efficiency.The only way for shipbuilding enterprises to enhance their competitiveness in the industry is to “complement the short board” as soon as possible to achieve full coverage of the lean shipbuilding model,and to use the combination of lean thinking and informatization to take the “integration of information and industrialization” of the new industrialization road,to implement the lean production management.Pipe processing workshop is one of the most important internal production workshops for shipbuilding companies and is the main processing and production place for providing the piping systems required during shipbuilding.With the development of production technology and the continuous renewal of production management theory,some shipbuilding companies have begun to introduce advanced digital and intelligent medium and small pipe processing lines to shorten the shipbuilding cycle.This production trend is inevitable.However,pipe processing workshops of most shipbuilding enterprises in China are still in the traditional manufacturing mode.The level of leanness is still relatively low,and there are still many deficiencies in production management.According to the current situation and trend of the production management in pipe processing workshop of shipbuilding enterprises,this paper analyzes the lean management of production management based on the “Dual-tray” management model,and makes detailed discussions on the production operation management model,the production plan management,the production logistics management and the production performance management,which are helpful to promote lean management on production management:(1)The current situation and existing problems in the production management of pipe processing workshops in shipbuilding companies were analyzed,and the ideas and goals for lean implementation in the production management of the workshops were proposed;On the basis of the “Dual-tray” management mode,the workshop business process is clarified.On the basis of this process and operation management,the process of pipe processing is planned,and the plant layout as well as the related infrastructure of pipe production can be optimized at the same time;(2)To study the lean production mode of pipe processing workshop production plan and operation system,respectively from the pull of production planning and control system,build the Kanban management pipe processing workshop Just-in-time production system and the detailed management system has been studied carefully,which has solved many problems affecting the lean production management in production planning;(3)Analyze the issues that need to be solved in the logistics management field of the pipe processing workshop management system in the shipbuilding company,and discuss from the perspective of the standardization and informatization of the lean logistics pipe processing workshop production operations;(4)Based on the requirements analysis of the production performance management in pipe processing workshops,the production performance assessment scheme based on the role of employees is constructed.The theory and the application are combined to elaborate the formulation,implementation,evaluation results and feedback of the performance improvement plan.Research contents of the thesis are the lessons for large or medium-sized shipyard that implement lean production management for reference.What's more,Thesis research contents for pipe processing workshop of shipbuilding enterprises and other manufacturing production management with lean idea and scheme,for implementation of the "Integration of information and industrialization" and "Made in China 2025" strategy to build a solid foundation.
