Research On General-Assembly Shipbuilding Mode

Over the past ten years, China's shipbuilding industry has been developing very fast. Especially, up to the end of August of 2010, completed newbuilding tonnage, China's new shipbuilding orders and reserved orders in hand both are on the top of the world. However, comparing with the powerful shipbuilding countries, China's shipbuilding industry yet has a considerable gap in the realm of management system. Only through carrying out production organization structure's change over, production management system innovation and shipbuilding process optimizing, and establishing modern shipbuilding mode, can China accomplish the transformation from a large shipbuilding country to a powerful shipbuilding country, the development direction of modern is general-assembly shipbuilding mode,.This thesis illustrates the definition and characteristics of general-assembly shipbuilding mode, it's core is intermediate products specialization manufacturing. On the basis of the theory of specialization separation, by means of system analysis, comparing general-assembly shipbuilding mode with conventional shipbuilding mode, with lean shipbuilding mode, and with the production center manufacturing shipbuilding mode, the thesis brings forward three elements, i.e., innovation of the production management system and the production organization structure, creating the general-assembly production flow processes, the relationship between the general-assembly yard and the intermediate products manufacturing center, which are used to study general-assembly shipbuilding mode. Further, the thesis sets the framework model of general-assembly shipbuilding mode, and the shipbuilding production planning management system of a combination of "Push" and "Pull", and general-assembly shipbuilding produciton management system as a result of production organization structure innovation based on "Authority distribution".The thesis analyzes the conventional shipbuilding flow processes. And based on the theory of 'restraint', the theory of'separating the main and auxiliary flow processes', and the theory of 'industrial mass chain', the idea of establishing the flow processes of general-assembly shipbuilding are put forth, which is characterized as the theory'Separating the main and auxiliary flow processes, Sequencing the activities in space', and systematically establishing the major production flow processes of general-assembly shipbuilding, and accomplishing the study of building specialization manufacturing center, forming the complete system of general-assembly shipbuilding mode. By means of metrological economics method, on the basis of classification categories of the intermediate products manufacturing center and the collaboration relationship between the general-assembly yard and the intermediate products manufacturing center, and by setting up the mathematics model, of quantitatively analyzing " Win-Win " collaboration relationship between the general-assembly yard and the intermediate products manufacturing center in respect of price and profit, and from the viewpoint of industrial mass chain, the thesis analyzes the collaboration relationship of tight type, semi-tight type, and loose type between the general-assembly yard and the intermediate products manufacturing center, which is of constantly challenging evolution action.The thesis, based on the theory of " New Increase ", introduces the concept of "General-assembled Ratio" that indicates the development level of general-assembly shipbuilding mode, and sets the appraisal mathematics model for general-assembly shipbuilding mode. By means of metrological economics method, utilizing real historical statistics obtained from a leading shipyard in China in the field of general-assembly shipbuilding, the thesis authentically ascertains and analyzes the production grouth contribution rate of shipbuilding mode, capital, science and technology, and human resources, etc. The thesis concludes the establishing general-assembly shipbuilding mode is crucial to increase production efficiency and general-assembly shipbuilding mode is the development direction of modern shipbuilding mode.Summarizing the above research works, the thesis gives the recommendations for paving the way of implementing general-assembly shipbuilding mode.
