BlockSim includes two independent computation modes: analytical and simulation (Figure 2.9). The analytical mode uses the exact reliability solutions for the system using the system's reliability function or cumulative density function (cdf). BlockSim can resolve even the most complex systems analytically and this method should be used when one is performing "reliability analysis." In the context of BlockSim and this reference, we use the term "reliability analysis" to refer to all analyses that do not include repairs or restorations of the component. In contrast to the analytical mode, the simulation mode takes into account repair and restoration actions, including behaviors of crews, spare part pools, throughput, etc. Both of these methods, analytical and simulation, will be explored in the chapters that follow in this on-line reference .
