Simulation Run Observations and the Output Report

00:03

The InfoWater Pro Scheduler can assist you in selecting cost-effective pumping policies

00:08

to reduce operational costs and provide more reliable operations.

00:13

Once you open the Scheduler and define the Input Data—Control Groups, Source Costs, Constraints, and Options—

00:20

you can run the optimization routine.

00:23

From the Scheduler Run menu, click Start.

00:26

When the Scheduler run is in progress, the status of the simulation is reported in the Simulation view.

00:33

While viewing the trial progress,

00:35

you can also see the current pump scheduling costs and any violations of system constraints in the optimized solution.

00:42

Make note of current penalties, as adjustments may be needed before re-running the optimization simulation.

00:49

The simulation is complete when the traffic light turns green.

00:53

The Message Board at the bottom of the Scheduler window displays a message upon successful completion of the simulation,

00:59

or any pertinent error messages.

01:02

If the simulation run is unsuccessful, a descriptive message appears explaining what needs to be corrected in the Input Data.

01:09

The Output Report view of the Scheduler is available after completing a successful Scheduler run.

01:15

The Output Report is divided into three main categories—the Control Schedule report, the Constraint report, and the Summary report.

01:24

The Control Schedule reports the simulation time and status of pump, valve, and pipe elements during the optimized schedule.

01:32

Switch to the Detail tab to see schedules for each individual element included in a Scheduler control group.

01:39

The Constraint report lists constraints, numerical results, and infractions from the last successful simulation.

01:46

The maximum violation is the amount over the maximum allowed—for example,

01:52

the max velocity for the simulation minus the specified max velocity constraint equals the max velocity violation.

01:60

To limit violations, you may consider increasing the penalty weighting factors, as needed.

02:05

You can also limit the optimization to smaller portions of the system.

02:10

The Summary category offers a summary of the optimization input, settings, and results.

02:16

Cost breakdown and constraint violations can also be reviewed.

02:21

Often, the results seen here are used to adjust the weighting in the Scheduler options before an optimization is performed again.
