Dear Researchers,

There are a lot of techniques like AHP, SWARA, ARAS, PIPRECIA, FUCOM etc wherein a group of experts are requested to give their opinions. My specific questions are:

1. How is the sample size determined?

2. What should be the sufficient sample size?

3. How sampling is carried out?

4. Any specific rule to determine the composition of the sample?

It would be of great help if any researcher answer my questions and share supportive literature.

With best regards,

Sanjib
