Evidence Acquirement and Combination Method Based on Rough Set in Ordered Information System

Abstract: A novel method of evidence acquirement and combination based on rough set was proposed by introducing evi-dence theory into the ordered decision information system.Confidence degrees of evidence are used to calculate approximate conditional probability assignments.Evidence weights are calculated according to the attribute significances and support degrees of evidence.Decisions are gained by using combinational rule to integrate approximate conditional pro-bability assignments.

Key words: Rough set,Approximate conditional probability assignment,Ordered information system,Evidence theory,Support degrees of evidence
