Optimization applications deal with numeric data. We find it easier to interpret when represented by

familiar units of measurement.



However, there is a risk of serious errors resulting from incorrect unit assumptions. Remember the Mars spacecraft NASA engineers lost due to this problem?



One solution is to add code to an application in order to convert a value measured in, say, miles to a value measured in kilometers. But this can cause loss of accuracy, is prone to errors, and can become difficult to maintain.



Luckily, AIMMS automates the task of adopting the numeric values to the units preferred by the user.
