Creating a Simple Markov Diagram
You have seen what a Markov diagram looks like in Windchill Markov. Now you can create a simple diagram:
1. Select the Markov Table.
2. Click <Click here to insert a new record> to insert a new diagram.
3. For Identifier, enter My Markov Diagram. An initial state is already inserted in the diagram for you.
4. Select the Markov Diagram pane.
5. Select > . The Insert State window opens.
6. Click OK to insert a state with the default style. When you move the mouse cursor in the diagram pane, it changes into the shape of the selected state style.
7. Move the cursor to the right of the initial state and click the mouse button to insert a state.
The cursor remains in the shape of the state style to let you know that you can continue to insert states, if desired.
8. Right-click to exit the insertion mode.
9. Select > to automatically connect the states.
10. Double-click the top transition line to open the Properties window.
11. For Rate, enter 0.00015 to indicate a failure rate of 0.00015 failures per hour; then, click OK.
12. Double-click the bottom transition line to open the Properties window.
13. For Rate, enter 12.5 to indicate a repair rate of 12.5 repairs per hour; then, click OK.
14. Double-click the right-most state to open the Properties window.
15. For State, select Failed; then, click OK.
This simple diagram models a system that begins in an operational state. Because it has a failure rate of 0.00015 failures per hour, the system eventually reaches the failed state. With a repair, which occurs at the rate of 12.5 repairs per hour, the system returns to the operational, or good, state.
