I have AHP, ELECTRE, TOPSIS and ANP results using other softwares. Now i want to simulate the decision matrix for 1000 iterations and check which methods are giving consistent results.
I don't have the proposal for the software you are searching for. But I was wondering - why do you even want to compare those methods results? AHP and ANP are based on pairwise comparisons - which might differ from user to user. You can have differences in comparing AHP with AHP on the same iteration considering different users...
Secondly, the structure of MCDM problem differ from method to method. How can you create a problem structure which is in the same time (hierarchy - as needed in AHP, network - as needed in ANP, or "linear" - as needed in TOPSIS/Electre)? I think you are trying to compare at least two different things in terms of possibility to compare...
