In this research, a design system with a virtual reality function was developed. The virtual world was realized by using GL4Java, liquid crystal shutter glasses, sensor systems, etc. And the Multi-Agent CAD system with product models, which had been developed before, was integrated with the VR design system. A prototype system was developed for highway steel plate girder bridges, and was applied to a design problem. The application verified the effectiveness of the developed system.}, subject = {Mehragentensystem}, language = {en} } @article{YabukiYoshimura2004, author = {Yabuki, Nobuyoshi and Yoshimura, Yutaka}, title = {An Evaluation System for Steel Structures of Hydroelectric Power Stations based on Fault Tree Analysis and Performance Maps}, doi = {10.25643/bauhaus-universitaet.256}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-2564}, year = {2004}, abstract = {This paper presents an evaluation system for steel structures of hydroelectric power stations, including hydraulic gates and penstocks, based on Fault Tree Analyasis (FTA) and performance maps. This system consists of fault tree diagrams of FTA, performance maps, design and analysis systems, and engineerin databases. These four modules are integrated by appropriate hyperlinks so that the user of this system can use it easily and seamlessly. A well developed system was applied to some illustrative example cases, and they showed that the developed methodology and system worked well and the users found the system useful and effective for their maintenance tasks at powerstations.}, subject = {Wissensmanagement}, language = {en} }
