The article presents two modules operating in a hybrid CAPCAST system implemented in the Department of Applied Computer Science
and Modelling, AGH University of Science and Technology, Cracow. These are the modules: CAPCAST-base of producers and
CAPCAST-base of materials. Registered producers may benefit from other modules of the system, the base can also be an independent
source of knowledge about Polish foundries and their production capacity, and can serve as a kind of platform for the implementation of
the basic functions of e-business. The base of materials can also be a source of knowledge about materials, and it allows searching and
filtering the lists of materials in terms of user-selected attributes using a multi-level search engine. This module is integrated with the rest
of the system and can be used by other modules. The system has been developed at the AGH Department of Applied Computer Science
and Modelling in Cracow.
