11. The next step is to insert 5 states into the model, corresponding to the following system states: both components
available, prime failed, standby failed, both prime and standby failed, and prime repaired.
12. From the Markov toolbar, click the State button (A). This button is used to start the insertion of new states into the
model.

13. Move the mouse-pointer into the Markov canvas, and click the left mouse button once. A green circle, representing a
newly created state, appears.
14. Move the mouse-pointer to an empty part of the Markov canvas, and left-click again. A second state appears in the
diagram.
15. Repeat the last step three more times. A total of five states should now be visible in the Markov canvas.
16. We consider that at time 0, both the primary and standby components are available, and that the system therefore is in
the first state. In other words, this state is the initial state.
17. Right-click the state S1 corresponding to the ‘both components available’ state. A popup menu appears.
