I need to mask my indexes names in WebUI tables the same way is possible to do in WinUI pivot tables using an string parameter. How I can do it? Example: Set Frubas := { '1', '2', '3', '4'} Ps_DescriptionFrubas('1') := "First" Ps_DescriptionFrubas('2') := "Second" ... In my WebUI table it appears as 1, 2, ... and it should appear "First", "Second" ...

Hi, the "objective function" of my program is read as a variable in AIMMS. All the parameters in the objective function already have a data read from excel. My problem is, AIMMS keeps on saying "the scope of index i has not been specified" when I try to specify the index, the program won't run because it will say that the objective function should be a free scalar variable. What should I do?

I'd like to launch WebUI automatically upon opening a project. I can't seem to locate the webui::pr_OpenWebUI procedure. Is there one? Thanks! ~Bon

Hi, How can I empty all sets except 1? I only want to empty self declared sets. I tried it with a for loop. However I have some trouble comparing the name of the set with a string. Kind regards, Wiet

The help feature for using a function is very nice: The auto-populate for inserting an element is also swell. But how about some kind of auto-fill for the functions themselves? Is there a keyboard shortcut for that? Thanks! ~Bon

Hello, I have created two histograms using "Histogramcreate" where the "HistogramSetDomain" are the same but the frequencies observed (using "HistogramGetFrequencies") are different. I have also drew the plots of the histograms separately. I am wondering if it is possible to show the two frequency histograms on the same plot? I appreciate any help in advance

Hello 1- I will try different constraints for my model. For example, I want to disable all constraints and show the results. I tried to created parameters as a below; parameter: IsDisable , range=integer Constraint: MyConstraint , index: (i,j) | not IsDisable But in index section in MyConstraint: " t | t>=2 " I could not add the " | not IsDisable " 2- Also How can I write the solution to excel? Could you please help me? Best Regards.

Hi, I'm making a model of flexible flow shop for academic project and I have a problem with declaring one set(or sets in fact). The set I'm talking about is a set of parallel machins which are bounded to specific stages. It looks more or less like this: t - stage index, t = 1, 2, 3, . . . , k i - machine index, i = 1, 2, 3, . . . , mt (t is upper index) Do I have to specify every set of machines seperatly for each stage or is there some convinient way of doing it?

Hi all, For our program, we have a 3*36 parameter input that we want to vary using a normal distribution for 1000 times in order to save the objective values to, eventually, create confidence intervals. We have the 1000 variation matrices, but we do not know manage to load these into AIMMS and let the program save the 1000 objective values. On the other hand, it is impossible to copy-paste these manually. Could you perhaps give us some advise on how to implement such a for-loop in AIMMS? Kind regards, Marten

Hi, For one of my projects, I would like to use the functionality multi-objective optimization with tolerance via the procedure GMP::Column::SetAsMultiObjective. Unfortunately, the results are not as I expected. Therefore I made a very small example to test this procedure. In the example, we have one variable (x1) which is nonnegative, one constraint (c1: x1 smaller or equal than 10) and two objectives: (obj1: x1 and obj: -x1). Moreover, the direction of the model (ex1) is maximize. To solve the example, I used the following code: myGMP := GMP::Instance::Generate( ex1 ); GMP::Column::SetAsMultiObjective( myGMP, obj1, 2, 1, 2, 0); GMP::Column::SetAsMultiObjective( myGMP, obj2, 1, 1, 0, 0); GMP::Instance::Solve( myGMP ); Based on the first objective (with the highest priority), I would expect the solution to be x1 = 10. Then, since we also have a second object and we allow the obj1 to have an absolute tolerance equal to 2, I would expect that the final solution would b

I often have thoughts/suggestions/questions on the documentation that have only to do with the understanding of the language (not AIMMS or anything mathematical). Do we have a sub-forum that users can ask or discuss things about that? In particular, right now I'm once again running into the situation where the documentation shows the text representation, but yet AIMMS doesn't allow the ability to directly code in text. So I'm wondering if there's a place in the documentation that shows how to convert text representation into what to put in the AIMMS GUI. Thanks! ~Bon

In WinUI (SO yesterday) we have the ability to assign a procedure to the on-double-click action in a Gantt chart. Is there yet a way to do this in WebUI?

I understand from this AIMMS WebUI Manual entry that the display domain should default to suppressing default values. I also understand that using a value of 1 shows all values (and 0 shows no values). But my graph is still plotting all the zero (default) values. For example, “Stranger” in this linechart has no values, but he still gets graphed. Am I misunderstanding something or is there a bug? Thanks! ~Bon

In the WebUI Gantt chart, under Settings > Add Gantt Layer, there is space for the Start and the Duration. However, both of these only accept parameters. I have a project with a full WinUI that needs to be converted, and it uses an element parameter as the Start. How can I use the element parameter as the start? Is there a way to do this directly? Or do I need to do a fancy workaround? Thanks!

I have a Gantt chart in WinUI that I'm trying to replicate in WebUI. The bars are colored based on the data (and a small bit of logic). I also have text on the bars. The only way I can find to make sure the text shows up is change the css. But the text doesn't respond to anything but the stroke property. Here's the css, and below is the result: code:.aimms-widget .tag-ganttchart .annotation-Red_100\% { stroke: black; fill: rgb(255,50,50);}.aimms-widget .tag-ganttchart .annotation-Green_100\% { stroke: white; fill: rgb(50,255,50);}.aimms-widget .tag-ganttchart .annotation-Blue_100\% { stroke: white; fill: rgb(50,50,255);}.aimms-widget .tag-ganttchart .annotation-Orange_100\% { stroke: black; fill: rgb(255,153,50);} Is there any other way to change the text without also having the stroke around the bar change? Thanks! ~Bon

Dear AIMMS Community, quick question: How could I specify a relative and an absolute path using axll::OpenWorkBook ? Thank you!

Hi, I was wondering if it is possible to see with which version of AIMMS an app was published on the PRO Cloud server?

Hi, We are facing some infeasibility issues trying to run our application in AIMMS PRO and we suspect it is due to the CPLEX version being used by PRO. Do you know how can we check and set the CPLEX version used by AIMMS PRO ? Thank !

Hi, Here I am again, with another question :) How do you recommend I set up an automatic routine which starts a new optimization run at 8.00 pm every day? Thank you!

I would like to know how to get the sensitivity analysis of a constraint shadow price. For example, say we have the following constraint: x+y ≤ c and its shadow price "SP". How do I get the relationship between c and SP ? In other words, the sensitivity analysis of SP according to c. I would appreciate if you can show me how to achieve this in AIMMS. Thank you very much for your assistance!

Is it possible to change the font size in AIMMS?
