The term decision matrix is used to describe a multiple-criteria decision analysis (MCDA) problem. An MCDA problem, where there are M alternative options and each needs to be assessed on N criteria, can be described by the decision matrix which has N rows and M columns, or M × N elements, as shown in the following table.
A decision matrix is a device used to describe multiple-criteria decision analysis (MCDA) issues. In an MCDA scenario, where there are M options to evaluate and each must be assessed against N criteria, a decision matrix offers a systematic approach, consisting of N rows and M columns, or M × N elements.
