## Abstract

Preference relations can provide a more realistic model of random phenomena than quantitative probability or belief functions . In order to use preference relations for reasoning under uncertainty, it is necessary to perform sequential and parallel combinations of propagated information in a qualitative inference network. This paper discusses the rules for such sequential and parallel combinations.
