A Computerized Integrated Knowledge Based System (CIKS)
is a computerized intelligent system of integrated
knowledge base systems providing the knowledge for
solving problems of a range of complexities. Knowledge
bases which can be incorporated into a CIKS include
databases, mathematical and simulation models, AI
systems, guides, handbooks, and standards and codes.
Along with these knowledge bases, a comprehensive CIKS
will include ways to obtain knowledge from distributed
knowledge sources using Remote Database Access (RDA) and
Agent technologies. The development of a CIKS involves
the following major steps: (1) defining the purpose of
the system and who are the intended users; (2)
identifying and developing the architecture for the
system; (3) developing an information model; (4)
developing a prototype system; and (5) establishing
methods for the maintenance of the system. The
reliability of a CIKS will depend on the quality of the
knowledge it contains. The needs for the establishment
of a validation process for knowledge bases and for the
complete CIKS system are discussed. Four examples of
the application of CIKS technology applicable to
high-performance concrete (HPC) are described to
illustrate the diversity of the technology. Also, an
operational, prototype CIKS which predicts the service
life of reinforced concrete, which is susceptible to
corrosion induced by an external source of chlorides, is
