Research the virtual assembly multimedia ship construction information system

This research proposes to build a "Multimedia Ship Construction Information System" to integrate the information of ship design and construction with the implementation document. The system exploits the characteristics of XML to present the electronic implementation document, and thus the information can be used repetitiously. It will then further develop into an extensible and reconstructible script language for the process script of ship construction. It integrates the virtual reality technology and establishes a mechanism that transforms text description into virtual assembly. A three-dimensional (3D) solid model of ship component built previously can be reused, and through the virtual assembly the visualization of implementation process simulation and planning can be conducted. Human intuition is used to present the construction information of the ship so that documents can be transformed from two-dimensional to three-dimensional form to accelerate the information flow on shipbuilding. With relational database technology, a multimedia (text and image) database on ship design and shipbuilding will be established through product data management (PDM), whose function is to control and manage documents to raise the value of information utilization. Moreover, the establishment of a wireless network not only can solve the communication problem between the internal shipyard and the construction site, but also assists the constructors to build the ship correctly, significantly elevate the quality of construction, and increase the working efficiency.
