Research About Ship CAD/CAE Integration System Based On PDM

Ship designing is involved in a many professions many systems, large scale collaborativework processes, the cycle is long, complicated. And in the ship designing process, because ofthe large amount of resulting documents, designing process requiring all professionaldesigners constantly coordinated, and due to the different professions using the differentCAD/CAE software, results in a lack of integrated design system, the lack of the control ofdesign process; the lack of the effective control and management on the electronic data; poorinformation exchanging, the existence of the so-called "information isolated island". shipCAD/CAE integration system based on PDM and related problem in this paper is the mosteffective method to solve this kind of problem with the information technology and thedevelopment of computer technology.The work in this paper accords to the following three main stages:The first stage: the building of integrated framework. Based on the research of current shipdesigning pattern, putting forward to study the needing analysis of concurrent andcollaborative design. On the basis of PDM, establishing the parallel collaborative shipdesign system structure, process and integration framework. And completing the parallelcollaborative ship design of heterogeneous software integration research, the integrated studyof the management of every ship electrical and mechanical professional designing behaviorproject, the management of document, the management of workflow, the management oforganization and other major functional modules.The second stage: the phase of implementation.Studying and selecting the appropriate PDMsoftware system and carrying out the function of the system through two developingtechnologies. That mainly includes two large pieces of content that the management of projectand the management of information sharing.The management of project is mainly toundertake unity planning and coordinate each link of the design, effectively master theschedule and make full use of their human resources, to improve the efficiency of design.Thetechnology of information sharing mainly includes the management of ship designingdocument, the customization of ship design processes, the achievement of monitoringfunctions, the integration of heterogeneous model and visual tools for application as well asplanning the ship designing projects and carrying out the supervision and the management.The third phase: the phase of operation, to analyze whether the proposed framework is to achieve the desired goal through designing examples on the prototype system.In this study, we propose a new multi-agent framework.Integrating the ship CAD, CAE andPDM software, and even ship designers, managers, other systems (such as OA, MRP, ERP)and auxiliary resources together, and supporting the design and development of collaborativeproducts with a unified interface. In essence, the system is a tool, which is the environment ofintelligent ship products collaborative design and development, but also a kind of thought,namely the thought of intelligent ship product collaborative design, this is the developmentaldirection of the ship designing and manufacture integration.Therefore, this study hasimportant theoretical significance and practical application value.
