title BECOC : A Knowledge Bank and its Use in Construction and CAD Systems
source The Computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered : ill. include some bibliographical references
summary The Development of the BECOC prototype (Structured Knowledge Bank for Construction Elements) was undertaken in order to test the integration of Data and Knowledge using the SITEC model (Construction Technology Information System). After the graphical definition of a building exterior, the assignment of the construction solutions is dynamically controlled using the Knowledge Bank for real time decision making. To represent the knowledge that acts on the data the knowledge bank consists of an Object Oriented Data Base and a Rule System, developed using the NEXPERT/OBJECT package. In this manner it is possible to establish relationships among properties, concepts, restrictions in values, structural relations and the control of standards compliance, which in this case has been limited to thermal, acoustic and weight requirements. The system helps the user to make decisions and it analyzes the context in order to make the deductions needed to maintain internal data consistency. The positive results of this work indicate the way for further developments, and demonstrate that expert systems and traditional technologies coupled together can be effective and give the desired answers in monitoring design in the everyday problems in construction technology
