Cost of Ownership of Spare Parts under Uncertainty: Integrating Reliability and Costs

In capital-intensive organizations, decisions regarding capital costs play an important role due to the significant amount of investment required and expected return on investment. Spare parts management is crucial those ends, as spare can constitute a portion OPEX. Companies must implement trade-off analysis between stock levels assets’ availability. Decision-making supports mechanisms such Level Repair Analysis (LORA), Integrated Logistics Systems (ILS), life-cycle costing (LCC) models have been developed aid in equipment selection, implementation, decommissioning. Nowadays, these appear be integrated with risk-management standards. This paper proposes long-term model that integrates capacity analysis, reliability functions, risk considerations for cost logistics activities, particularly MRO structures. The built upon Time-Driven Activity-Based Costing (TD-ABC) incorporates volume activities generated by needs. It also addresses uncertainty through integration cost-at-risk model. By integrating parts, activity-based models, measurement Monte Carlo simulation, this study offers powerful insights into optimizing activities. proposed novel approach include management, its matrix-activity-based structure makes possible development sophisticated mathematical optimization purposes different domains.
