How it works:
- The user selects specific sites that should be
considered as possible sources in the Sources column.
- Then the sourcing policy chooses the source
from the user-defined sources, which best satisfies the specified
There are three groups of policies:
- Fixed Source
group - at the beginning of the experiment the specified policy chooses
one source. It will be the only source the customer will be using
during the whole experiment.
- Dynamic Sources group - in
contrast to the Fixed Source policy,
the source is chosen anew for every new placed order, so the
source may change during the experiment according to the current
situation (depending on the current inventory level of the source at
the order generation).
- Multiple Sources group - In this
case all the available sources willbe supplying the customer
simultaneously, i.e. the demanded amount of products will be
split between the available sources either equally or as
defined by the user.
Let us describe how the best source is
- In case of dynamic sourcing policies the
sources are filtered by their current
inventory level of the required product - only the sources with
sufficient amount of products are considered.
- If there are several alternative paths connecting
pair (delivery destination, source), then the best path is
according to the policy specified in the Path
Selection Mode table for this pair.
- Finally the best source is selected by
considering the specified sourcing policy (using the path
selected in the previous step).
The following sourcing policies are
Users may use their
own custom sourcing policies. Once added, they will be
available in the bottom of the policies list.
- First - Chooses the
first source (in the order of
appearance) from the list of possible sources selected
in the Sources column.
- Cheapest - Every
user-selected source is considered by its transportation costs
(specified in the Paths
table). The cheapest source is chosen.
- Closest - Chooses the
closest source to the customer.
- Fastest - The source
is chosen in terms of the delivery time.
- Most Inventory (Dynamic
Chooses the source with the largest
available volume of the product (e.g. the
customer ordered 10 items and the
selected sources may offer 10, 7
and 10 items respectively. The second source will be omitted
because it does not cover the ordered amount. Since more than
source satisfies the
demand and both of them contain similar volumes, random source will be
chosen among them).
- Uniform Split (Multiple Sources) -
amount is split equally among the available sources,

there are 5 available sources, the customer will receive 40 items from
- Split by Ratio (Multiple Sources)
- The demand is
split among the available sources according to the ratio defined in the

Defines parameter values for the Split by Ratio
and custom policy types
The Split by Ratio is configured
with the following parameters:
- Drop order is source is unavailable - the toggle
button defines if the demand of the unavailable source must be dropped or distributed among the rest of the available
e.g. Let us assume that the demanded amount is
evenly split among 5 sources, and one source is unavailable. If the
toggle button is enabled, one fifth of the demanded amount
will be dropped. If the toggle button is disabled, one fifth of the
demanded amount will distributed among the available sources.
- Site - the sourcing facility supplying the customer
- Ratio - the demand percentage that will be supplied
by this facility. You may specify any numbers here, they will be
normalized by the experiment. For example, if you have 5 DCs with ratio
set to 5, 15, 7, 1, 9, the experiment will bring those values into
alignment by diving each number by the sum of all the values (5 / 37,
15 / 37, 7 / 37 etc.)
(Source in GFA)
Defines possible sources (or a single source in case of the GFA scenario type) for the specified product. It
can be any supplying facility (defined in the DCs
tables), except for a Customer.
Note: A supplier
cannot be set here if you are working in the GFA type of scenario.
You can use the following techniques when working with the drop-down
list of possible sources:
- To set / unset a facility as a source, select / clear
the check box next to the list item;
- To set a facility as a source and
simultaneously unset all other facilities, double-click the list item;
invert the check box state for the selected items, prese the Space key
on the keyboard. You can select several items by holding the Ctrl key
while clicking the items you need to select. You can also select a
range of items by clicking the first item in a range and holding the
the Shift key while clicking the last item in a range.
