信頼性、可用性、保守性、安全性（RAMS）

Reliability, Availability, Maintainability, and Safety (RAMS) is a critical framework in product design and engineering that ensures systems perform consistently and safely throughout their lifecycle. It emphasizes the importance of designing products that not only function reliably under expected conditions but also remain accessible for maintenance and are safe for users. By integrating RAMS principles, organizations can enhance product quality, reduce downtime, and improve overall user satisfaction.
