Abstract: In view of knowledge base’s structure characteristics of blending optimization expert system in production of alumina with sintering process,an on-line maintenance method of expert knowledge base based on similarity measure is proposed.At first similarity measure function of rule is defined;then it is described in details how to take consistency check and orderly on-line add and modify rule following the original knowledge organization strategies by similarity measure so as to ensure highly effective expert inference.The on-line maintenance method proposed is applied successfully to industries.

Key words: knowledge base maintenance, similarity measure, production of alumina with sintering process, blending optimization, expert system
