	Some systems are made up of independent series, parallel, series, series-parallel, parallel-series, k-out-of-n, and redundant subsystems. The reliability of such an engineering system (presented in Figure 4.17 on page 85) is computed at 600 hours of mission time. Each component has an exponential life distribution model with a different lambda. Failures rates are presented in table below.

	This example is solved by the system reduction method, which involves collapsing a system sequentially into the foregoing susbsystems, each represented by an equivalent reliability block, until the entire system is represented by a single reliability block. The system reliability is calculated as 93.67%.
