Understanding scenarios

00:03

Info

00:04

works.

00:04

WS pro includes scenario management functionality that helps you plan what

00:08

if analyses and possible future design iterations for a model.

00:13

New scenarios can be kept separate from a copy of the base

00:16

model while still sharing data within the version controlled commit history.

00:21

When creating and working with scenarios,

00:23

it is important to have a matching network and control.

00:25

Open

00:27

scenarios can be used to model variations of a network

00:30

simultaneously without the need to create separate branched networks.

00:35

For example,

00:36

scenarios can be a very useful tool if used to investigate

00:39

the impact of different object parameters like size and material on simulations

00:45

scenarios can be derived from a base network or other scenarios,

00:49

but they do not appear in the model group window as separate entities,

00:54

they are saved within the network interviewed by opening the network

00:58

and selecting the scenario to be viewed from the scenario's toolbar.

01:02

Any changes made to the base network are copied to scenarios.

01:07

If changes are made to a field of a network object in a scenario,

01:11

so that the value of the field in the scenario

01:14

differs from the value of the field in the base,

01:16

then any further changes in the base network to the

01:19

same field will not be carried over to that scenario.

01:23

If further changes are made to the same field in the scenario,

01:27

so that the value of the field in the scenario is set to the same as the base.

01:31

The link between the objects in the base and scenario is reestablished

01:35

and changes made in the base will be visible in the scenario.

01:38

Again,

01:41

network objects present in the base scenario but not in the current

01:44

scenario are displayed as a faded gray color in the scenario.

01:48

GEO plan window

01:50

display of these object ghosts can be turned on and off

01:53

from the visual page of the GEO plan properties dialogue.

01:57

The scenario's toolbar contains options that allow you to view excluded

02:01

objects in a grid and restore them to a scenario.

02:06

It is important to note that scenarios are not

02:08

structured in the same way as most info works.

02:10

WS pro objects

02:13

scenarios can be created from a base network and any subsequent

02:16

change to the base will cascade down to the scenarios.

02:21

It is also possible to create copies of scenarios,

02:25

copied scenarios are independent duplicates or direct copies of the scenario.

02:29

They originate from

02:32

scenarios that are copies of the same scenario are not linked in any way

02:36

and any changes made to the original scenario

02:38

do not cascade down to the scenario copies.

02:42

Consider an example in which you generate two scenarios from a base

02:47

scenarios. One and two are independent from each other.

02:51

However, changes made to the base will cascade down to both.

02:55

If you then make duplicates of scenario 11 A and one B, for example,

02:60

those are also independent from each other

03:02

and changing one will not affect the other

03:06

editing or deleting. Scenario one will also have no impact on one A and one B.
