SUMMARY  OF  MY  DOCTORATE  THESIS  AND  CELLULAR  AUTOMATON  MODEL  –  RUBENS  ZIMBRES  [email protected]    

This document is a brief explanation of the steps of my Doctorate thesis. Samples of results are given. The Cellular automaton model is presented.

The  thesis  is  available  here:  http://pt.slideshare.net/RubensZimbres/thesisrubens-­‐zimbres    In  my  doctorate  thesis  I  studied  4  constructs:  role  clarity,  involvement,  service  quality  and  behavioral  intentions  in  the  following  nomological  network.  The  research  was  diadic  and  dynamic,  made  with  clients  and  service  providers.      

   For  each  one  of  the  constructs,  I  did  a  comprehensive  research  where  knowledge  acquired  was  inserted  in  a  matrix,  as  seen  next  page.

   Then,  indicators  cited  in  literature  were  placed  in  another  matrix,  correlating  authors.

 Then,  the  research  phases  are  presented.    

       After  that,  I  did  qualitative  interviews  to  develop  the  pre-­‐test  questionnaire.  Interviews  were  transcripted,  contente  analysis  was  done,  compared  to  literature  and  quantitative  pre-­‐test  questionnaire  was  developed.  Then  I  did  a  statistical  analysis  and  I  finally  had  the  quantitative  questionnaire,  below.  An  ordinal  scale  of  5  options  was  chosen  to  allow  respondents  to  have  a  neutral  opinion,  without  being  forced  to  choose  between  two  opposites,  what  happens  in  a  scale  with  6  options.  Next  page  there  is  a  small  part  of  the  questionnaire.

   A  comprehensive  statistical  analysis  was  done.  Here  are  some  results:    Graphic:  Time  as  a  cliente  of  the  servisse  provider

 A  descriptive  analysis  was  done:    

   

   Normality  tests  were  done:  

   Also,  collinearity  tests  were  done:

 Correlations  with  factor  1  and  2    

     Factor  analysis  and  Cronbach's  Alpha  (for  clients).    

   And  the  regression  model,  with  principal  components:

 Finally,  the  cellular  automaton  model  was  developed  to  simulate  interactions  between  clients  and  service  providers.  I  did  two  quantitative  researches  with  interval  of  4  months.  Research  A  and  B.  My  idea  was  to  find  a  cellular  automaton  that  could  be  applied  to  research  A  (first)  and  generate  an  outcome  of  the  simulation  similar  to  research  B  (second,  after  4  months).

   I  had  to  find  a  rule  in  a  space  of  1  in  10  to  the  power  of  80  possibilities.  This  would  take  more  than  200  years  with  a  regular  computer,  so  I  did  a  randomly  guided  search.  The  cellular  automaton  is  a  tool  where  you  have  three  cells.  The  center  cell  is  updated  according  to  the  opinion  of  the  cells  on  the  left  and  on  the  right.  Each  CA  rule  generate  on  specific  outcome.

     Next  page,  the  cellular  automaton  model  workflow:    

Page 10: Scientific Market Research

     The  accuracy  of  the  cellular  automaton  model  to  simulate  interactions  was  73.80%  case  by  case  and  99%  considering  mean  of  indicators.  This  is  greater  than  any  linear  regression  found  in  service  quality  literature.
