Scaling by Lp Norm Illustration

We shall illustrate using norm for scaling. The norms for the three criteria are computed using Equation 6.10. 

The criteria values are then scaled by dividing them by their respective norms and are given in Table 6.22. 

Scaled Criteria Values Using Norm (Example 6.5) 

Note that the scaling by norm did not convert the minimization criterion (TCO) to maximization as the previous two methods (Ideal value and Simple Linearization) did. Hence, the TCO values have to be multiplied by (-1) before computing the weighted score. Note also, that the norm of each criterion (column) in Table 6.22 is always 1. 

Once again, the rankings are the same, namely Supplier A, followed by Suppliers B and C.
