So a simple question for you that I hope you can answer and let us and other community members know: What makes you want to use AIMMS (and not other tools)?

New List Widget

Dear community, I like to share that we are currently building a new widget that we have called a List Widget.

For example, when there is execution going on, but it’s just above the default threshold and you do not w...

Consolidating _tooltips, _flags and _text identifiers into Identifier Annotations

I want to let you know that we are in the process of consolidation the mentioned identifiers to specify e.g. the readonly flag, define a tooltip, or the text in a Gantt char item, will receive it’s own annotation in the identifier specification. This is a more elegant way and will make the model mor...

Article Download file to a specific location ("save as") instead of the default download folder

We had a few times the question whether it’s possible to do a ‘Save File As’ when using the Download widget - instead of the typical placement in the download folder. Please know you can adjust the browser settings to always ask where to save a file before downloading. For example in Chrome: For d...

Tables Totals, what to do?

There has been quite some discussions on the Totals of a table in the AIMMS WebUI.

However, the totals are based on all values that exist in the identifier, so f...

Watch Window
