🔶Please  read  and  understand  the  following  important  instructions:    

1.   All  work  for  case  studies  will  be  submitted  as  Excel  workbooks.  Please  create  different  worksheets   for  each  part.  Label  these  sheets  “Part  a”,  “Part  b”,  etc.  If  an  answer  requires  other  sheets  (e.g.,   “Sensitivity  Report”),  rename  them  referring  to  the  part  of  the  problem  to  which  it  corresponds.   Always  include  an  “Introduction”  sheet  as  the  first  worksheet  (see  below).       2.Make  ample  use  of  colors,geometricshapesandobjects,framedcellsandranges,TextBoxes,   Comments,  Word  Art,ClipArt,backgrounds,  etc.,  to  enhance  the  presentation  and  appear-­  ance  of   your  sheet.  Don’t  go  overboard  and  risk  losing  clarity  and  legibility  or  having  the  sheet  look  gaudy  

 

🔴Grading.  Points  are  allotted  according  to  the  following  scale:    

Model.                                                                    Maximum  of  70  points.     Presentation                                                  Maximum  of  20  points.     Use  of  Excel  Features                    Maximum  of  10  points.    

🔹Model:  

 The  model  is  the  conceptual  part  of  the  problem.  If  it  is  a  linear  programming  formulation,  for  example,  the   model  criterion  is  applied  to  check  whether  the  formulation  is  correct  and  whether  it  was  entered  and  solved   correctly  in  the  Solver.  Here,  what  matters  is  the  right  answer  in  all  the  parts  of  the  case  study.    

🔹Presentation:  

This  measures  how  well  the  problem  is  presented  for  the  reader  to  un-­  derstand.  All  variables  should  be   defined  using  words.  The  formulation  should  be  clear  by  just  looking  at  the  sheet  where  the  data  appears   including  aspects  such  as  the  constraints,  objective  function,  sense  of  optimization,  sense  of  inequalities,  etc.   This  should  be  in  addi-­  tion  to  having  the  algebraic  formulation  explicitly  stated  in  a  separate  TextBox.  The  case   studies  usually  involve  interesting  applications  requiring  ingenuity  in  the  way  the  problem  is  formulated.   Therefore,  the  formulation  should  be  discussed  in  words  in  a  separate  TextBox.  Feel  free  to  make  use  of   TextBoxes  to  discuss  other  issues  that  arise.  Range  names  should    

be  clear  and  should  be  such  that  they  appear  in  the  Solver  Window.  Special  cell  comments  should  further   elucidate  more  specific  aspects  of  the  problem.  The  optimal  solution  should  be  presented  and  described  in   words  in  its  own  TextBox.    

🔹Excel  Features:  

This  is  the  “cosmetic”  part  of  the  evaluation.  The  criterion  is  how  well  Excel  features  such  as  those  described   above  enhance  the  appearance  and  utility  of  the  presentation.
