관계TM: Reliability Verification
When designing systems that provide critical service or infrastructure, the system is expected to comply with strict reliability requirements.
These requirements are often defined in the specification, and they should be considered by the system engineer as early as possible in the design process.
During the initial stage of the design, the system reliability should be verified using a high-level model, where reliability is allocated, from system to assemblies, based on the assembly complexity, experience, field data or by similarity.
Later, as the detailed design is created, a reliability verification should be conducted based on a detailed reliability model.
