Creating demand categories

00:04

Categorizing demand and info works W S pro allows you to easily

00:08

visualize different demand profiles which can

00:11

be crucial for planning new developments.

00:14

In this example,

00:15

you will create a new demand category representing

00:18

a school within a planned housing development.

00:21

Before starting be sure to copy session five dot wpt into your database.

00:26

Open the bridge net GEO plan and work

00:28

within a new scenario named housing development.

00:32

This new scenario will need a node

00:34

with allocated demand linked to the existing network

00:38

from the model group window under demand diagram group select

00:42

Bridgetown ad A W to open the demand diagram.

00:48

Click add

00:51

this displays the new demand category dialogue

00:55

from here in the category name field.

00:58

Enter a descriptive name for the new category such as school

01:02

to use demand data from a live data

01:05

source from the factored direct section select direct

01:10

ensure the data link is set to manual which allows the

01:13

category data in the demand diagram editor to be entered manually.

01:19

Click. OK.

01:21

The demand diagram opens again with the demand category set to

01:25

the newly created category which in this case is named school.

01:30

Now you can manually enter the data for the new demand category

01:34

from your devices, file explorer, open the school profile text document.

01:40

The data in this document represents a demand pattern for a 24 hour period

01:46

from the document, select all the data and copy it.

01:50

Then back in info works ws pro demand diagram under daily values,

01:56

select the top left cell and paste the data

02:00

with the data pasted into the diagram. Click save.

02:05

You can now use this new demand category.

02:08

Return to the GEO plan and create a new scenario

02:13

from the toolbar select scenario,

02:15

create scenario

02:18

in the create new scenario, dialogue name this scenario,

02:22

housing development plus school and select copy an existing scenario

02:28

from the scenario to copy drop down. Ensure housing development is selected

02:34

click OK.

02:37

Now in the toolbar select properties and then in the

02:41

GEO plan select the node that represents the planned development

02:46

from the development nodes properties window under demand,

02:50

select the demand by category ellipsis button,

02:54

the demand by category dialogue displays

02:58

in the second row, expand the demand category drop down and select school

03:05

set category type two direct

03:09

in the direct demand factor cell enter one

03:12

so that it is not given a multiplier

03:16

click. OK.

03:18

Commit the changes to both the bridge net network and the bridge con control.

03:24

Now that there are three scenarios in this model,

03:27

you can create a new run to simulate all three of them

03:32

from the model group window, right, click run group and select new

03:36

run

03:41

in the schedule. Hydraulic run dialogue

03:43

name the run housing development plus school and set two experimental

03:50

drag the bridge net network into the network section.

03:54

And from the scenarios tab select all three scenarios and then click run

04:02

in the warning dialogue, click yes to continue.

04:06

Once the run is processed, it displays in the model group window.

04:12

You may need to expand the link tree in order to navigate to it.

04:17

You can now open the base scenario simulation

04:20

and then open the other two simulations.

04:22

As alternate results. For comparison

04:28

to compare results,

04:29

you could use the graph command to select the development node to

04:32

visualize the differences in flow or pressure for the three scenarios.

  1. In the ribbon, select Scenario > Create scenario.

In the ribbon, the scenarios menu with Create scenario selected.

  1. In the Create New Scenario dialog box, enter the name “Housing development + school”.
  2. Select Copy an existing scenario.
  3. In the Scenario to copy drop-down, ensure that Housing development is selected.
  4. Click OK.

The Create New Scenario dialog box with the name entered, Copy to an existing scenario enabled and highlighted, and Housing Development and OK selected.

  1. In the Tools toolbar, select Properties.
  2. In the GeoPlan, select the node that represents the planned development.

The Tools toolbar with Properties selected, and the GeoPlan with the planned development node selected; both highlighted in red.

  1. From the Properties window, Demand section, in the Demand By Category field, click More ().

The Properties panel with More (…) selected next to Demand By Category.

  1. In the Demand By Category dialog box, second row, expand the Demand Category drop-down and select School.
  2. Under Category Type, select Direct.
  3. In the Direct Demand Factor cell, enter “1” (so that it is not given a multiplier).
  4. Click OK.

The Demand By Category dialog box, second row, School selected under Demand Category, Category Type set to “Direct” and Direct Demand Factor set to “1”.

  1. Commit the changes to both the BridgeNet network and the BridgeCon
