The allocation of demand to nodes throughout a water supply network
00:07
is crucial to the accuracy of the simulations in info works.
00:11
WS pro
00:13
because consumer demand varies throughout the day, day of the week and time of year.
00:18
Demand categories provide 24 hour profiles for a particular type of consumer.
00:24
Typically,
00:25
consumers belonging to a particular demand
00:27
category will have similar demand patterns
00:31
to define demand patterns.
00:32
You can use the demand diagram which contains categories that
00:36
define the demand pattern for an individual type of consumer.
00:40
In this example,
00:41
you will assign a demand category and specific consumption
00:44
properties to a node for a planned housing development.
00:48
Before starting, you will need to copy session five dot WPT into your database.
00:54
Open the bridge net GEO plan
00:56
and work within a new scenario that has a new node linked to the existing network
01:02
to assign a demand category to the newly created node.
01:05
The demand diagram needs to be open
01:08
from the database model group window,
01:10
expand demand diagram group and then select Bridgetown ad A W
01:17
the demand diagram dialog opens
01:21
next open the properties panel for
01:23
the node representing the future housing development
01:27
from the toolbar, select properties. And then in the GEO plan select the new node
01:34
from the properties panel under demand.
01:36
Notice the demand by category option
01:39
select more which is the ellipsis button to open the demand by category dialogue.
01:45
A demand category can be defined in one of three ways.
01:49
In
01:49
this example, you will define demand per property
01:53
from the demand by category dialogue, expand the demand category dropdown.
01:58
This list is populated by the categories contained in the
02:01
current demand diagram which is running in the background.
02:06
Select domestic
02:08
then expand the category type drop down and select property
02:13
in the number of properties field.
02:15
Enter an estimation for a number of properties within the category such as 100
02:22
in the specific consumption field.
02:23
Enter an estimation of consumption for each property in the category such as 400
02:30
click OK.
02:32
Notice in the GEO plan,
02:33
the node shape updates to a star which represents the new allocation of demand.
02:39
After allocating demand to the node,
02:41
you can then verify the scenario and commit the changes to the master database
02:46
to commit the changes from the model group
02:49
window under session five right click bridge net.
02:52
And from the shortcut menu, select commit changes to master database
02:58
in the comments field. Enter a description of the changes you made and then click OK
03:04
to run accurate simulation results.
03:06
It is critical to allocate appropriate demand
03:08
categories to objects within a model group.

In InfoWorks WS Pro, allocating demand to nodes throughout a water supply network is crucial to the accuracy of simulations. Because consumer demand varies by time of day, day of the week, and time of year, demand categories provide 24-hour profiles for a particular type of consumer.
The demand diagram contains categories that define the demand pattern for an individual type of consumer. This example assigns a demand category and specific consumption properties to a node for a planned housing development.
To open the Demand Diagram window, which must be open:
To define the demand category for the node representing the future housing development:
Note: A demand category can be defined in one of three ways. This example defines demand per property.
Note: This list is populated by the categories contained in the current Demand Diagram, which is running in the background.
Notice in the GeoPlan, the node shape updates to a star, representing the new allocation of demand.
To verify the scenario and commit the changes to the database:
IMPORTANT: To run accurate simulation models, it is critical to allocate appropriate demand categories to objects within a model group.
