Model Data Input
Figure 12-7 - Selecting the Scheduler Model
The Scheduler model requires the following information:
1. Number of phases in a cycle
2. Time duration of each phase
3. Cryptic names of model variables which are manipulated in a cycle
4. Value of each model variable in each phase of the cycle
The input data to the model is set by using the input form of the scheduler model. The
input data form is as shown in Figure 12-8. A brief explanation of each input variable is
given below.
Number of phase in sequence: This variable defines the number of distinctive
phases in a cyclic-sequence. The default value is set to 8.
Duration of each phase: This variable defines the time duration of each phase.
The sum of the time duration of each phase is equal to the total sequence (cycle)
time. Figure 12-9 shows the input form for setting the duration of each phase.
Cycle start phase: This defines the phase at which the cycle starts. The value of
the variable can be between 1 to number of phases defined above.
Cryptic name of model variables– This defines the cryptic names of the model
variables which are manipulated in each phase. By default, a maximum of
10 model variables can be used to set the sequence. All the variables are set to
blank (nothing is manipulated in the sequence). To include a model variable in
the scheduler set-up, the blank should be replaced by the full cryptic name of the
variable available in the layout. For example, to set the influent flow rate for an
influent object in the sequence, the blank variable can be replaced by qconinf
