Decision-Making Approach to Selecting Optimal Platform of Service Variants

Algorithm 1

Pseudocode for quantification of design spaces (, ).

INPUT:   = Size of each subgroup, - number of subgroups

       = binary Service Model 1 - if -th row links with -th column; 0 - otherwise,

      GR = general restriction - diagonal restriction

      SR = specific restriction - off-diagonal restriction

OUTPUT: ΣVar = Sum of variation with specified restricion

PROCEDURE Sum_Var(, , Iteration=0, Row=1, From=1)

     IF N<2 THEN RETURN ΣVar ← 0

      = Row

     DO

         FOR j=1,…,

              IF Iteration=N-2 THEN ΣVar+=M[i,j]Product(M[j]);

              ELSE IF M[i,j]Product(M[j])<>0  THEN

                  ΣVar+=M[i,j]Sum_Var(,M,Iteration+1,i,j);

         i=i+1;

         IF ITERATION<>0 THEN RETURN ΣVar;

     UNTIL i<=  ;

     RETURN ΣVar

END PROCEDURE
