(i), we calculate tangent similarity measures for different values of [lambda] between ideal alternatives (Table 5) and the decision elements in Table 4 (see Table 6).
The elements of the depot location problem as defined are, however, only part of a wider set of decision elements associated with distribution strategic planning.
Examples of other distribution decision elements which interact, to a greater or lesser extent, with the elements of the depot location problem include:
