Features: Lean production is one of the most advanced production models in the world today. Its success has sparked a wave of lean management worldwide, and the principles of lean management have brought tremendous progress to various manufacturing industries globally. Through long-term research on the production models of advanced Japanese shipbuilding companies and combining the practical experience of Chinese shipbuilding companies in transitioning their shipbuilding models, this paper uses the theory of lean management to comprehensively and systematically analyze and study lean production methods and approaches in the shipbuilding process, and for the first time proposes the concept of lean shipbuilding. The starting point of lean shipbuilding is to eliminate non-value-added time in the shipbuilding process to reduce resource waste and improve resource utilization, thereby achieving the results of shortening shipbuilding cycles, reducing shipbuilding costs, increasing shipbuilding output, and enhancing shipbuilding efficiency. Implementing lean shipbuilding involves all aspects of shipyard management, including market development, budget planning, operational production, design and technology, material procurement, human resources, financial management, as well as equipment and safety management. This paper elaborates in detail on the arguments and methods of lean shipbuilding from various perspectives, such as operation decomposition, value chain analysis, planning management, precision shipbuilding, and factory management, including effective and ineffective product value chain analysis, zero-inventory just-in-time (JIT) production systems, flexible single-piece flow production systems, balanced and continuous production rhythms, customized pull planning systems, harmonious operation of people and materials through 4S management, defect-free construction quality management systems, multi-skilled job skill systems, and total factory management, providing Chinese shipbuilding enterprises with a systematic and highly operational modern shipbuilding model.
Chapter 1 of this paper analyzes the current state of Chinese shipbuilding and proposes that high shipbuilding costs and low efficiency are the two major obstacles restricting further development. Lean shipbuilding can effectively address this issue. Chapter 2 elaborates in detail on the principles of lean shipbuilding. Chapter 3 discusses the method of operation decomposition in lean shipbuilding in the context of shipbuilding processes. Chapter 4 analyzes the value chain of lean shipbuilding using value engineering methods. Chapter 5 provides a detailed explanation of the planning management system of lean shipbuilding. Chapter 6 introduces the theory and methods of shipbuilding precision management. Chapter 7 elaborates in detail on the application of 4S management in total factory management.
In the face of rapid development in Chinese shipbuilding, the author hopes that through the research on lean shipbuilding, Chinese shipyards can establish a modern shipbuilding model with high technological content, good economic benefits, low resource consumption, minimal environmental pollution, and full utilization of human resources, enabling China's shipbuilding industry to truly become a major and strong shipbuilding power in the world during the next round of industrial shifts.
