Fortna Inc. has upgraded its DCmodeler software, a tool that can analyze many years worth of item, order, receipt, shipment, and inventory data. Version 3.0 of this proprietary tool includes data simulations that help users evaluate alternatives and "tipping points" as they design their distribution operations.

The tool can analyze each item's dimensions, weight, velocity, and inventory requirements and then recommend the best storage media for each item. It can also analyze seasonal trends at the item level. This information can help companies choose the best inventory level for a particular product at different times of the year as well as select the best facilities and automation for handling its inventory.
