The following equation is employed to aggregate the normalized preference values of alternatives (Churchman and Ackoff 1954):

(2.9)

in which V_i = the overall preference of the ith alternative. Equation (2.9) is found on most compensatory methods and implies that poor performance of an alternative with respect to some criteria can be compensated for by high performance by other criteria.

Despite its simplicity, the WSM remains a top choice of decision‐makers for evaluating an MADM problem. A conceptually similar method to WSM is the weighted product method (WPM), which is discussed in Section 2.3.
