add-in places new items under the OR/IE menu. Choose Add
Inventory to create the inventory definition on
the worksheet. The Optimize command is used
to construct optimization models of multi-item systems.
The System command builds systems of inventory
components. The New Functions/Buttons command
is necessary when a worksheet is opened that contains
functions created by the add-in on a different computer.
In order to see the results on the demo workbook, you
will have to choose this command first. This must be
done for each worksheet that contains functions or buttons.
Inventory models all involve some
level of abstraction from reality. The first abstraction
removes all statistical variability from the situation.
Thus we call these models deterministic. The
