| Shipbuilding industry is very important in our country. The development level of the shipbuilding industry reflects the comprehensive strength of Chinese political, economic, military and other aspects. From the beginning of twenty-first Century, Chinese shipbuilding industry has been developing rapidly, various kinds of advanced information technology also has been coming one after another. The informatization work of ship industry gradually has been gotten attention, and all kinds of CAD, CAM, ERP, MES software have been implemented and achieved remarkable results. With the informationization development of shipbuilding industry, the “information island” phenomenon of different application software continues to appear, PDM starts into people’s attention as a data integration platform role, the major shipping companies are constantly trying to apply PDM in information management system. In this paper, through the analysis of the domestic and foreign typical PDM product, and the product data management application status in the domestic shipbuilding enterprises, there are a series of problems in shipbuilding product data management, such as leaning to document management, various difficulties in system integration and so on. The article put forward product data management system of shipbuilding industry should be based on product structure as the core idea. It combines modern shipbuilding mode theory, domain drives design as software-development method and the information system of data integration technology as the theoretical basis of the study. The research is based on the product structure management in PDM system and application of product data management system as integration platform in the shipbuilding industry. The aim of this research is to improve the ship product development and information integration level of design and manufacturing process and to lay the foundation to improve the life cycle management of ship products in shipbuilding enterprise. The main research content of this article is:1) Analyze ship product design and business process, combined with the classical PDM products, and research the ship product data management system’s overall function architecture and the overall technical architecture with product structure as the core, the design data of ship CAD/CAM system as the source, PDM as an integrated platform of enterprise application integration framework, other shipbuilding management system as the terminal of product data flow.2) According to the design characteristics of the ship products and BOM structure with various, high complexity, large amount of data, the article respectively researches several aspects such as data organization mode of ship product structure in the PDM system, product configuration management, multi-view product structure and BOM data extraction.3) Because of the particularity and the closure of ship CAD/CAM system, the research focuses on the integration information extraction and conversion between ship CAD/CAM system and PDM system, including the integration mode of model attribute information, model structure information and model geometry information, product manufacturing information, drawings and documents. It realizes the integration between ship CAD/CAM system and PDM system.4) In order to realize the sharing of product design data in ship enterprise, the integration of PDM system and the other shipbuilding management systems is the one of points in the research. Through design and definition the specification of integration data model between PDM system and other shipbuilding management systems, the article illustrates the integration mode of different types of issued information in PDM system, including product material data, product manufacturing data, product project data, drawings and documents. It realizes the integration between PDM system and other shipbuilding management system. |
