WIZE: A knowledge-based documentation and database software system in the field of fatigue at high temperatures

The paper presents objectives and results of a research project the aim of which is the development of a knowledge-based ('intelligent') documentation and database system (WIZE) in the area of high temperature fatigue strength.The system is controlled by a module developed within the knowledge-based system (KBS) shell and it provides also an 'intelligent user-interface'. The database part is developed in a relational database system, but an upgrade towards object-oriented network-like database structure is being made. The part contains data for 30 groups of materials relevant for high-temperature power plant applications (e.g. turbine materials) and helps to derive the corresponding crack initiation curves. The documentation base is developed in a full-document oriented hypermedia system. The navigation through the information space of stored hyper-documents is controlled by the KBS-based part. Future development includes application of neural networks. (author)
