Economic Design of Multivariate EWMA Chart for CBM- A Direct Approach
This paper proposes a multivariate Exponentially Weighted Moving Average (EWMA) chart for conditionbased maintenance (CBM) purpose. Specifically, the multivariate EWMA chart is used to monitor machine condition to increase system reliability and to avoid costly failures. The objective is to determine the interval between samples, the control limit, and the MEWMA exponential weight minimi/ing the expected average cost per unit time subject to the constraint guaranteeing the occurrence of preventive repair before failure with given probability. The average cost formula is derived using results from renewal theory and applying a direct approach and a numerical example is provided.
