ResumoA majority of the reliability studies and the theoretical models focus their attention to system consisting of small consumable (non-repairable) components. But, in the present day practice most of the elements or components constituting the system are repairable. This paper includes a study of repairable systems for computing parameters such as, availability, maintainability, and reliability. The failure data for a period of 3 y was collected from M/s Escorts Limited, Bahadurgarh (Punjab) for machines (4 in number) engaged in the production of various types of pistons for automobiles. The data was analysed and the performance of the machines complied based on the failure data clearly indicates that the machines have high availability and good reliability but poor maintainability. Suggestions are made to improve the maintenance of these machines.
