Abstract

Degradation modeling and maintenance decision-making based on degradation information are two majors issues in the field of reliability and maintenance research. This paper proposes an s-plane (complex plan) approach to deal with these two issues. A well-known mass-spring-damper dynamic system is considered as a case study. The loss of spring stiffness and of damper friction degrade the system performance over time. We show that the location of the system pole in the s-plane could be a good indicator to characterize the degradation of the whole system. Based on such an indicator, a maintenance policy is proposed to reduce as much as possible maintenance costs. We use the distance between the current and initial locations of the system pole to trigger maintenance on the system. Without any direct information on the components, we exploit the relative location of the system pole in the s-plane to decide which component (spring, damper or both) should be replaced. The performances of the proposed policy are pointed out via numerical comparisons with a more classical policy.
