System Availability Simulation with Preventive Maintenance in Breakdown

예방적 고장정비를 고려한 시스템 가용도 시뮬레이션

Purpose: This paper reports on a simulator whose development considered the operational characteristics of a desalination plant while evaluating its performance.Methods: An availability simulator was developed and its performance evaluated through comparative analysis with results achieved both mathematically and with a widely used commercial software. For performance evaluation, we generated example systems including well-known basic structures and conducted an experiment on it.Results: Experimental results showed that the developed software produced results close to the known inherent availability derived from a commercial software. The known operational characteristics of the seawater desalination plant further verified the accuracy of the produced results.Conclusion: We have proposed practical considerations and developed a simulator for a desalination plant. It is expected that the proposed method and the developed software will contribute to advance the plant"s Operation and Maintenance (O&M) performance.
