Abstract: With the development of domestic economy, the production scale of refining and chemical enterprise is expanding, which puts forward higher requirements for the reliable and stable operation of distribution system. For distribution equipment, the traditional work mode of regular maintenance and breakdown maintenance has been difficult to meet the demand. With the continuous development of AI technology and computer technology, condition-based maintenance will replace the traditional maintenance in the future. Therefore, the condition-based maintenance decision making technology of distribution equipment is deeply studied, and the decision making system is developed and applied. The system determines the operation status evaluation according to the actual operating status, and evaluates the operation health status of the distribution equipment, and makes maintenance decisions and suggestions according to the evaluation results, so as to reasonably arrange the maintenance plan and make the equipment operate safely and efficiently. The application of the system provides technical support for the scientific decision making of distribution equipment maintenance and the rational allocation of human resources, and makes the management of enterprise distribution system more efficient and scientific.

Key words: refining and chemical enterprise, distribution equipment, condition-based maintenance, decision making system, time model, failure probability, reliability, minimum cost
