An  Extension of  Gitlow's Methodology for Designing Abortion Clinics 
In [I] Gitlow presented a methodology  for determining the optimal design of  an 
abortion clinic, combining a simulation model with a steepest ascent algorithm. In his 
conclusion  the  author  stated  as  a  main  limitation  of  his  methodology:  " . . . the 
necessary number of  clinic configurations increases exponentially (2"), rendering the 
methodology impractical when considering a large number of  variables".  However, I 
disagree  completely  with  the  author's  modesty!  A  large  number  of  variables  in 
so-called Response  Surface Methodology  (RSM) which includes the steepest  ascent 
search algorithm, can be handled as follows: Do not simulate all 2"  combinations, but 
select  a  much  smaller  subset,  e.g.  only  n + 1  combinations,  applying  statistical 
methodology of  experimental design. Actually experimental design is a standard part 
of  RSM;  see  [2],  [3].  Experimental  designs  are  also  discussed  in  Gitlow's  own 
references. Hicks and Mendenhall.
