1. RELIABILITY OF 2-COMPONENT PARALLEL SYSTEM
Obtain an explicit expression for the reliability of a system consisting of a parallel arrangement of two components, C1 and C2 , with respective reliabilities, R1 and R2. Explain in words what the expression for the system reliability means in terms of the status of each component.
2. RELIABILITY OF 2-COMPONENT AND 4 COMPONENT PARALLEL SYSTEMS
If two of the identical components of Example 21.1 are now arranged in parallel (instead of in series), ?rst obtain the system reliability for this 2-component parallel con?guration. If two more identical components are added in parallel, obtain the system reliability for the resulting 4- component parallel con?guration.
