Evaluating The Reliability and Availability of A High-Pressure Die Casting System Featuring Two Units and Cold Standby Redundancy
Year: 2025
Type: article
Abstract: This study presents a behavioral and availability analysis of a high-pressure die casting plant modelled as a two-unit system with cold standby redundancy. By investigating the effects of varying repair rates (α) on system availability, we demonstrate that increased repair rates correlate positively with availability, aligning with practical expectations in industrial applications. Application of the regenerative graphical technique (based on the center of pressure) allows for evaluating the parameters very quickly without involving the computation of state equations or resultants. Our analysis highlights the potential inclusion of multi-unit systems with perfect and imperfect switch-over devices to broaden the model’s applicability. Additionally, insights are provided for conditions under which failure and repair rates may vary, offering directions for future profit-and-loss analysis. We discuss how operational costs can be minimized by leveraging expertise gained through repeated server visits, thereby reducing the need for primary interventions. This study offers a flexible framework for evaluating various system states and assessing key performance attributes, with implications for cost-effective maintenance strategies in industrial settings.
