In particular, if w = [(1/n, 1/n, ..., 1/n).sup.T], then the ITWD becomes the interval 2-tuple normalized distance (ITND) operator:
If the sets of interval 2-tuples [mathematical expression not reproducible] are degenerated to the sets of 2-tuples [mathematical expression not reproducible], then the ITWD is reduced to the 2-tuple weighted distance (TWD) operator:
Based on the OWA and the ITWD operators, we define an interval 2-tuple ordered weighted distance (ITOWD) operator as follows.
If [omega] = [(1/n, 1/n, ..., 1/n).sup.T], then the ITOWD becomes the ITND; if the position of [mathematical expression not reproducible] is the same as the ordered position of [mathematical expression not reproducible], then the ITWD is obtained.
Clearly, the fundamental characteristic of the ITWD operator is that it considers the importance of each given interval 2-tuple distance, whereas the fundamental characteristic of the ITOWD operator is the reordering step, and it weights all the ordered positions of the interval 2-tuple distances instead of weighting the given interval 2-tuple distances themselves.
In particular, if w = [(1/n, 1/n, ..., 1/n).sup.T], then the ITHWD is reduced to the ITOWD operator; if [omega] = [(1/n, 1/n, ..., 1/n).sup.T], then the ITHWD is reduced to the ITWD operator.
In this example, we consider the interval 2-tuple maximum distance, the interval 2-tuple minimum distance, the ITND, the ITWD, the ITHWD, the ITOWD, the ITOWGD, the ITOWHD, the ITOWED, and the ITOWCD operators.
From Table 8, it can be observed that the ranking orders of the alternatives obtained by the methods of Xu  and Wei  are exactly the same as those determined by proposed approach when the ITND, the ITWD, the ITOWD, the ITOWED, and the ITOWCD operators are applied.
