Chapter 3 Decision Support Model (IUWS-DSM) - Tubdok

54 New Conception and Decision Support Model for IUWS
If WUU is designed as the single project, then it can exactly follow the procedure in
Figure 25. If WUU is designed within UD, after managing its water usage, it needs to go to
superior level for requesting the necessary information firstly (as shown in Figure 22).
Thereby, the procedure is further developed.
3.2.3 Planning of water entity of ZONE type
In the hierarchy, the planning procedure for water entities of ZONE type is the combination
of the two procedures in Figure 22 and in Figure 25. The entire planning procedure of
CA is shown in Figure 26. As the inferior water entities of CA, the planning procedure of UD
is already embedded in. If the procedure is used only for UD, the steps of a.i, a.ii and a.iii in
Figure 26 are skipped. As there are interactions between water entities in different levels, the
iteration is needed in order to achieve the appropriate and optimised solutions.
