IV. Reliability Modeling and Prediction
A. Reliability Modeling
2. Reliability block diagrams and models (Create)
Generate and analyze various types of block diagrams and models, including series, parallel, partial redundancy, time-dependent, etc.
There are plenty of ways to improve a systems reliability performance through redundancy.

Quick Quiz
1-143. Which of the following are two basic types of redundancy?
(A) active and inactive
(B) active and standby
(C) parallel and series
(D) parallel and standby
(B) active and standby
Active redundancy means all the elements are active. Standby redundancy includes some components that are waiting to become active when necessary to replace the functionality of a primary (active) set of components.
Inactive redundancy is not a phrase used to describe a redundancy configuration. Parallel and series are reliability block diagram models used to describe the arrangement (reliability-wise) of elements of a design.
