Reliability Assessment on Assembly Line Due to Random Failure of Mechanical Component: A Case Study in an Automotive Ancillary Unit

Abstract

This paper presents reliability and availability analysis of a mechanical component which is a part of an assembly line. Mechanical component failed due to deterioration or poor operating condition, so scheduled as well as preventive maintenance policy is adopted. A scheduled maintenance and preventive maintenance is to improve the degraded components life. Degraded life of component is modelled by a reliability equation. While doing the preventive maintenance of an assembly line first component within the line identified. Also deteriorated components is to replace by new one as per preventive maintenance process suggested. A genetic algorithm has been used to investigate the failure data and down times. An assembly line reliability and availability has been estimated from the actual failure data collected.
