Select the activity you want to see simulated on the PPR 
        tree. 
        
          
            
              | 
            You can also select an activity that exists under a resource 
            task (e.g., a robot task or a human task), or a process, or you can 
            make no selection.  In the last case, the process is simulated. | 
           
         
         
        - 
        
Click Process Simulation  
        on the Simulation toolbar. 
        
          
            | The icon turns orange.  The Process Simulation 
            and Simulation Control Tools pop-up toolbars appear. |

		Activity Options (On/Off)
          
        on the Simulation Control Tools pop-up toolbar. 
        
          
            | The Activity Options dialog box appears. | 
           
          
              | 
           
          
            | The dialog box automatically contains the name of the activity 
            or process selected in Step 1 and the process used as a context for 
            the selected activity (that is, either a process or a resource 
            task). | 
           
         
         
        - 
        
(Optional) Select whether you want to see 
        only the selected activity (the default) or the current process from the 
        current activity to the end. 
        
          
            
              | 
            If the selected activity is the process, changing the Run 
            till the end of option has no effect. | 
           
          
            |   | 
            If you select Selected Activity, the Apply 
            button remains unavailable.  If you select Current Process, 
            the Apply button becomes available.  Once you press 
            it, it becomes unavailable until you make another selection in the
            Run till the end of area. | 
           
         
         
        - 
        
(Optional) Enter a Start or
        Stop Time or both. 
        
          
            
              | 
            If you enter invalid values for the start/end times, you get a 
            message to that effect after clicking Apply; a new time 
            is proposed. | 
           
         
         
        - 
        
Click Apply. 
        
          
            
              | 
            When you switch from one option to the other and click 
            Apply, the simulation pauses to apply the information.  
            If you go from Current Process to Selected Activity, 
            the process simulation starts from the selected activity. No changes 
            to the Activity Options dialog box take effect until the
            Apply button is clicked. | 
           
         
         
        - 
        
Click Run  
        on the Process Simulation pop-up toolbar to view the selected 
        portion of the process. 
        
         
        - 
        
End the simulation using one of the methods below: 
        
          
            
            
              - Press the X (close) button in the upper right hand 
              corner of the Process Simulation pop-up toolbar OR
 
              - Click Process Simulation
 
              (the command changes from orange to its original colors).
