| Complex model engineering plays a pivotal role in national economic development and national security.The thesis discusses the optimization strategies,methods,and paths of R&D management based on lean thinking,so as to guide the reform and improvement of enterprise R&D management to adapt to the ever-increasing market demand and fierce competition environment in the future.The thesis takes commercial space launch vehicle as the object of complex engineering products,takes lean thinking as its soul,and takes R&D management optimization as the guidance to establish a research and analysis framework.First of all,the purpose and significance of the research are guided by the background of the topic;secondly,it summarizes the development history and current status of lean production,lean thinking,and lean R&D at home and abroad,and analyzes and refines the relevant project management,R&D management and other theories;Thirdly,a detailed analysis of the elements of the complex model engineering enterprise and project management level is carried out,and the general mode,essential characteristics,problems and dilemmas of the complex model engineering R&D management are highlighted;Finally,use the theories and viewpoints of lean thinking to decompose and analyze the optimization of R&D management,explore the key points and growth points of management optimization,explore the route of lean management optimization,and tests the effect of management optimization through the application practice of launch vehicle R&D management in our enterprise.The thesis organizes and analyzes the literature to grasp the connotation of valuable research results,and through research and investigation to grasp the current situation and problems of enterprise R&D management truly;At the same time,the composition,influencing factors and relationship of R&D management theory and phenomenon are reasoned and verified by empirical research method,and the optimization effect is predicted and tested by establishing a basic operation model.After meticulous and rigorous analysis and research process,this thesis constructs a lean road for R&D management optimization.The lean road covers all aspects of core of R&D management,its core is to focus on the value of management work,reduce the waste of management work,and make the value of management work flows continuously and smoothly. |
