Dear Samia Fekih

I apologize for my delay in Answering your response; I had not seen it before

1) I agree

2) I agree

3) I disagree. Weights are trade-offs and thus, they are useless to evaluate alternatives.

AHP is unable to be used here because stakeholders may generate criteria that are interrelated

Pair-wise comparison is not acceptable.You cannot put a preference value at your will.

4- I do not know what you mean with alternative generation. As a fact alternatives must precede the selection of weights. You cannot assign weights on something that yo don’t of know

5- Please tell ne how you evaluate impact assessment

Cost-benefit analysis is not a MCDMA technique. It is a simple ratio, ans was developed long befre MCDA
