aom IS THE CONCEPT OF "TO AUTOMATE THE QTP ITSELF"

we can close Qtp from Qtp by using the Automation object 
model.
Automation object model is nothing but collection of 
objects,methods and properties which are used to perform 
quicktest operations.Throught this object model we can 
perform any operation described in QTP interface. 
For every option in QTP menus(Interface) have 
Objects,methods and properties are there in this model.
Eg:  dim qtApp
     set qtApp=createobject("QuickTest.Application")
     qtApp.Launch  /*It launches the QTP
     qtApp.visible= "true" /* Qtp is visible to us
     qtApp.close  /* It closes the Qtp

i agree with u, but i have one doubt in that scenario
how to execute the AOM program, can u explain

Write the above script in notedpad and save it with .vbs 
extension.Open the file and run it.

Essentially all configuration and run functionality 
provided via the QuickTest interface is in some way 
represented in the QuickTest automation object model via 
objects, methods, and properties. Although a one-on-one 
comparison cannot always be made, most dialog boxes in 
QuickTest have a corresponding automation object, most 
options in dialog boxes can be set and/or retrieved using 
the corresponding object property, and most menu commands 
and other operations have corresponding automation 
methods.  
You can use the objects, methods, and properties exposed by 
the QuickTest automation object model, along with standard 
programming elements such as loops and conditional 
statements to design your program

Aom is the automate the qtp,Functions,Libraries,and Object Repositories.ini..etc now i am writting aom script Launch QTP,Minimized qtp,maximized qtp, and close the qtp
dim qtapp
set qtapp=createobject("QuickTest.Application")
qtapp.launch
qtapp.visible=True
qtapp.windowstate="minimized"
qtapp.windowstate="maximized"
qtapp.windowstate="minimized"
qtapp.windowstate="maximized"
qtapp.quit
write that script on notepad and save .vbs file u can click that script automate qtp and close the qtp
