Research on Technical Condition Evaluation of Equipments Based on Matter Element Theory and Hidden Markov Model

Abstract

Scientific and reasonable technical condition evaluation is one of the effective methods to guarantee the safety of equipment. Considering the characteristics of equipment technical condition evaluation, such as the dynamic nature, the correlation of evaluation indexes and the hidden characteristics of the technical condition, a method of technical condition evaluation based on matter-element theory and hidden Markov model is proposed. On the one hand, this method makes use of matter-element theory to convert the evaluation indexes into compatible problem; on the other hand, the hidden Markov model is used to dynamically optimize the hidden technical condition change regulation in order to get a scientific and reasonable technical condition evaluation. The simulation results show that the method proposed in this paper can effectively reflect the dynamic nature and stability of the technical condition evaluation, and provide a new way for the equipment technical condition evaluation.
