  Using SimPy and Discrete Event Simulation we have observed the different
model responses of a system consisting of a hospital and people getting
sick/healing under different initial conditions.
  In our model, each independent person can get sick at an exponential rate.
The hospital's capacity is limited and accepts only a limited amount of sick
people. When the hospital gets full, people are sent home to heal. This is
simulated under different conditions and the simulation results have
demonstrated that the model reaches the steady-state in every scenario. These
cause the outputs of the simulation to be similar to each other even when the
simulation is run with different initial conditions. The results are compared
with the Machine Repair Problem and Erlang-Loss System and the model is
validated.
