The report consentrates on a case study concerning the
development of expert systems for
construction. The study was carried out over a two month
visit to the Loughborough University of Technology in
England. During the study an expert system prototype
called the BRICKWALL DAMAGE EXPERT system was developed.
The system and its development work are described. A
brief review on expert system development for
construction in the U.K. is also included.
Rather than adhering to rapid prototyping the development
of the BRICKWALL DAMAGE EXPERT system was composed of
some quite systematical phases as following
1. Setting the initial requirements for the structure
and functions of an expert system: The determination of
goals, the problem solving strategy and some requirements
for the user interface.
2. Collecting and analyzing knowledge by means of
computer aided tools: The use of computer aided drafting
tools to collect and analyze knowledge for the system.
The main principle behind the phases listed above was to
assess the practical implications of making the knowledge
acquisition and analysis more systematic and thereby
speeding up the process of expert system development
The system developed is a diagnostic expert system which
through inference procedure aims to determine the most
probable cause of brickwall damage. The system works in
question-answer mode. First an initial question
pertaining to the symptoms of the noticed crack is posed.
According to the reply given by the user the system
reduces the number of possible causes and thereby the
number of possible further questions. The consultation
ends with a list of possible causes and their
corresponding probabilities are displayed as a result.
