Recall Example 5.6 discussed in Section 5.3.7. Determine the ranking of the suppliers using the following methods:

a. L1 norm to scale the criteria values and L1 metric to rank

b. L2 norm to scale the criteria values and L2 metric to rank Do you find any rank reversals including the rankings obtained in Section 5.3.7? Explain any differences.

Example 5.6:
Consider a supplier selection problem with three suppliers A, B, and C and three selection criteria—TCO, service, and experience. The criteria values are given in Table 5.27. TCO has to be minimized, while the service and experience criteria have to be maximized.
