Simulation Modeling
Imitation of the operation of a real-world
process or system over time
Objective: to collect data as if a real system
were being observed
Data collected from the simulation are used
to estimate the performance/dependability
measures

Reliability
R(t) = probcfw_S is fully functioning in [0,t]
Suppose from [0,t] time period, we measure out of N components,
of which N0 (t): # of components operating correctly at time t
Nf (t): # of components w
