MADM methods can be classified as single or group decision‐making methods depending on the number of decision‐makers involved (Black 1948). In the case of single decision‐maker methods, the opinion of that single individual forms the preference evaluation mechanism of the decision‐making process. On the other hand, group decision‐making enables a number of experts and stakeholders to contribute and influence the decision‐making process (Kiesler and Sproull 1992). Group decision‐making methods are founded on the basis of single decision‐making methods; yet, they require an additional strategy through which, each decision‐maker’s opinion is aggregated and integrated with others’ viewpoints to form the final result. Exploring such strategies falls outside the scope of this book.
