Research on Spare Part Requirement for Repairable System Based on the Quasi-Renewal Model

Abstract:

The spare part requirement forecast is the base of maintenance management. The exact requirement forecast an important approach to improve availability and safety of the equipments and reducing the life cycle cost of equipments. The spare part requirement are not exactly forecasted under the traditional renewal suppose, hence it easily cause waste of money and backlog of goods. To improve the ability of repairable system spare part supporting under the imperfect maintenance, this paper researches on the spare part requirement forecast for the repairable systems under imperfect maintenance, provides the spare part requirement forecast models based on quasi-renewal theory and calculates the lower and upper bounds of systems availability. Finally, an example reveals the efficiency and operability of the model.
