Post-Evaluation of Electric Power Construction Project Based on Grey Rough Set

Abstract

The post-evaluation of electric power construction project is an important link, which is necessary in electric grid projects cycle. An advanced method of post-evaluation is proposed by combining Rough Set (RS) theory and Grey System (GS) theory, defined as Grey Rough Set (GRS). According to post-evaluation project experiences, this paper provides the method of index screening by attribute reduction and weight decision.
