Abstract
Knowledge-based systems are computer programs achieving expert-level compe-
tence in solving problems for specific task areas. This chapter is a tutorial on the
implementation of this kind of systems in the framework of credal networks. Credal
networks are a generalization of Bayesian networks where credal sets, i.e., closed con-
vex sets of probability measures, are used instead of precise probabilities. This allows
for a more flexible model of the knowledge, which can represent ambiguity, contrast
and contradiction in a natural and realistic way. The discussion guides the reader
