1 Right mouse-click an empty area of the diagram workspace, and choose Diagram Properties (or choose Edit > Diagram Properties from the menu).
2 On the Sim Diagram tab, enter a Simulation Parameter definition named Hotel Reservation, and then click Define to define it.
3 Specify simulation values as shown in the figure below.
