Product Model Support for Idealizations

• Idealizations - Relations between simplified analysis-oriented attributes and detailed design-oriented attributes.

  

• Example 1: Geometric Idealization, Gamma.1

  	total length = base length + 2 * sum (thicknesses) 
  

• Generally,

  	a.k  =  Gamma.i(d.1, ..., d.j, ..., d.n)
  

  where

  	Gamma.i = idealization relation i
  
  
  	    d.j	= design-oriented attributes, (j=1...n)
  
  
  	    a.k = analysis-oriented attribute k
  

• Example 2: Composition Idealization, Gamma.2

  	Part		Body Style   	primary structural material
  	-----------------------------------------------------------
  	resistor	   SMD		   base material
  	microprocessor	   LCC		   case material
  	PWB		    -		   core material
  

• As part of a PM, idealizations are usable in potentially many analysis models.
