Intelligent information acquisition and utilization in safety evaluation decision making process of power generation enterprises

Abstract

Modern information technologies are playing an increasing importantly role in safety production assessment of thermal power plants (TPPs). This paper investigates historical knowledge acquisition and utilization issue in safety evaluation of power generation enterprise and provides a case-based approach for the safety assessment decision making of TPPs (MSSATPP). A case matching method named CBR-Grey which ingrates Delphi approach and Grey System theory is proposed. Based on this method, we implement a prototype of information acquisition and utilization system (CBRSYS-TPP) for MSSATPP. We use this system to complete two distinct comparative experiments and validate the effectiveness and excellent comprehensive performance of CBR-Grey. CBRSYS-TPP is hopeful to be a powerful decision tool for panel of experts during their evaluation. © 2012 Springer-Verlag.
