Before proceeding to the first step, the decision matrix must be created by the decision-maker. The rows of the decision matrix correspond to options, and the columns correspond to criteria to be used in decision making. It is created by evaluating each option according to each criterion. The size of the matrix is m×n to indicate the number of options, m, n the number of criteria.
Step 1: Creating the standard decision matrix; Step 2: Creating the weighted standard decision matrix; Step 3: Determination of ideal and anti-ideal solutions; Step 4: Calculation of the separation measure; Step 5: Calculating the relative closeness to the ideal solution; Step 6: Sorting options
