Root Cause Analysis on the Nature of Breakdown for Computerized Maintenance Management System

Equipment failures are triggered by initiating events called root causes, the identification of which can aid in preventing the failures. However, unpredictable nature of certain failures renders the determination of root causes, difficult. In this paper, a knowledge-based approach that uses a combination of Six Sigma technique, Cause and Effect technique, and Pareto Analysis technique is implemented to assist and investigate the breakdown of assets through Root Cause Analysis (RCA). The foremost objective of this RCA method is to reduce adverse events from recurrence, in a proactive manner. The proposed method has been validated using ventilator breakdown data collected from Narayana Health (NH) over seven years, encompassing failures and associated operating parameters.
