-----------------------------------------------------
-- This procedure compute DAG system (Result) from attributes of Sys (input model) following
-- the transformation of SCM (spacewire communication model).
-- In this procedure, we must provide :
   -- destination_tasks and source_tasks : two tables which describe source and destination tasks of Sys
   -- A_link_matrice : matrice includes used links by message of Sys,
   -------- to compute A_link_matrice, we need compute task_position of source and destination tasks, then
   -------- we need to compute used links in the network by messages of Sys.
