Maintenance Activity Planning on Cenrtifugal Pump System With Failure Modes and Effects Analysis (Fmea) Method Based on Fuzzy Cost Estimation and Reliability Centered Maintenance II Method

摘要

Background: Without any system that is able to identify the malfunction, causes,udimpacts and detection method as well as the the cost occurred from quality problem,udsuch maintenance activity plan would fail in deciding which maintenance activity isudaccurate and has the ability to anticipate surrounding problem, product quality, andudultimately, the cost occurred from quality problem. Objective: This research that tookudcase study in PPP company are aimed to (1) decide accurate maintenance activity forudcentrifugal pump components which concern about the causes and effects of suchudfailures, (2) to decide optimum maintenance interval, and (3) to analyze the systemudimprovement after applying the combination of Reliability Centered Maintenance IIudand FMEA Method Based On Fuzzy Cost Estimation methods. Results: The researchudreveals the priority item that its characteristic should become a reference of the wholeudcentrifugal pump maintenance, based on its highest RPI score. The result of thisudresearch shows the maintenance requirement activities to handle failures fromudequipment. Futhermore, the implementation of methods proposed in this research givesudimprovement of down time which decreases to 17 percent and saves the maintenanceudcost by 20.5 percent. Conclusion: In order to have good maintenance system, it shouldudbe designed with the reliability-assurance-oriented approach with failure costudconsideration. The combination of Reliability Centered Maintenance II and FMEAudMethod Based on Fuzzy Cost Estimation methods could fulfill those needs.
