DCs and Factories

Production and storing facilities are the integral components of every supply chain. This table is used to specify distribution centers and factories that comprise your supply chain. Data for this table can be collected automatically from the results of the GFA experiment or inserted manually for each DC/factory that you create.

To optimize the quantity of supply chain components per costs involved, refer to Facility expenses table (available in the NO and SIM scenario types).

To specify the type and the quantity of vehicles that a site possesses, refer to the Fleet size table (available only in the SIM scenario type).

If you change the type of the facility, the icon on the GIS map will change respectively.




Specify the name of the DC/Factory. It must be a meaningful name since you will refer to it in other ALX tables.


Site type. The default site type is “DC”, but it can be replaced with your own site type.

Select the type of the site:

  • DC - distribution center. A type of a warehouse with additional customer services.
  • Factory - production site, the source of products that supply chain provides customers with.
  • DC with staff - custom DC with staff involved.
  • DC with storages - custom DC with a number of areas.
  • XFactory - custom factory.


Specify the current location of the DC/Factory.

Double-click the corresponding row cell to open the drop-down list and choose among the available Locations.

Initially Open

[Available in NO and SIM scenario types]

Specifies if the facility is initially open. A facility can change its state only once during Simulation and Network Optimization based experiments.

Inclusion Type

Defines the status of the current facility.

  • Include - if set, the facility will be included into the supply chain configuration.
  • Exclude - if set, the facility will be excluded from the supply chain configuration. If selected, the table record will be grayed out to denote the current inclusion type. The table record stays editable.
    Note: If you feel that your scenario contains too many objects marked as "Excluded" and you know that you no longer use them, you can instantly remove all such objects.
  • Consider - if set, the facility can be turned off/on during scenario optimization (only during network optimization).


[Available in SIM scenario type] 

The maximum inventory amount (physical capacity of a facility) in the specified Capacity Unit.

When inventory is replenished, the replenishment order's quantity will be adjusted automatically to meet the capacity limit of the facility (inventory replenishment parameters are defined in the Inventory table). 

If capacity is defined for a facility, the inventory replenishment logic is the following:
  1. If inventory for a product can be replenished in full quantity, it is performed according to the specified replenishment parameters.
  2. If inventory for a product cannot be replenished because of the capacity limit, the record in a special FIFO (First In, First Out) queue is created for this product. Inventory for the records in this queue is checked on each outgoing shipment and is replenished as a first priority.
  3. Inventory replenishment under a regular inventory check (as defined in the Inventory table) is performed as a second priority.

Capacity Unit

[Available in SIM scenario type]  

The measurement units that the Capacity is measured in. 

Note: The list of available units comprises the units defined both in the ALX Preferences and the Units table.

Interest, ratio per year

[Available in SIM scenario type]

Interest ratio in the interval (0,1) .

Aggregate Orders by Location

[Available in SIM scenario type]

allows you to accumulate orders for a number of customers located in one location. The option is unchecked by default.

Additional Parameters

[Available in NO and SIM scenario types]

Here you define an icon that will represent this particular object only. All other objects of this type will keep their current icons.

Note: If you convert the current object to the object of the custom type, the current icon will remain.

 Initially the default   and icons are set for all DC and Factory objects repectively (can be changed in Edit Icons).
