Shipbuilding layered production plan system

The production planning of shipbuilding contained stratification,grade complation,implementation and execution.To realize these steps,according to milestone plan,the shipbuilding layered production plan system was proposed by taking segment lifting as core.The 4D plan system description method was used to depict hierarchica relation,task decomposed relation and product input/output relation between plans.By comprehensive consideration of integrated hull construction outfitting and painting,the plan system's coordination of design and production was studied from single project and multi-project respectively.The space rescoure and labor resource were utilized adequately.Every production link,production mode,resource management organization and each decision-making level were covered by system completely,and the features of shipbuilding production and management mode were embodied.
