Can anyone please suggest an appropriate method for integrating DEMATEL - ISM methods used to identify the causal relationships in between the parameters ? I have seen few papers in which 'lambda' value is considered to prepare reachability matrix (ISM) from Total Relation Matrix (DEMATEL) but the basis for selecting 'lambda' value is still not that clear?
DEMATEL can be effectively used to find the cause and effect groups by finding r+c and r-c values. You can separate those groups and find the influence of causal drivers on effects using digraph-matrix approaches. Please see my publications.
You can use Maximum Mean De-Entropy Algorithm (MMDE) to set the threshold.
After the threshold is found, the total-relation matrix (T) generated by DEMATEL can be transformed into reachability matrix of ISM. If tij is greater than threshold, then tij is set to 1, else tij is set to 0.
