I am looking to solve a multi-objective chance-constrained blending problem. Are there any suggestions about the software to use to try and solve a problem like this?

    $\begingroup$ I have edited your title to include multi-objective optimization, and also to avoid the word "best", since your question doesn't ask for the "best", and since such a question would be subjective (and therefore not a great fit for OR.SE) anyway. Feel free to re-edit the title if I've introduced any errors. $\endgroup$ Commented Apr 14, 2020 at 13:18

You may be interested in the following paper because it uses chance-constrained programming and bi-objective optimization together in a transportation application:


I would suggest to do the followings for your problem:

1- If you have bi-linear terms in your formulation then try to linearize them using for example "Piecewise mccormick relaxation".

2- Generate a reasonable (and tractable) number of scenarios to generate/expand the chance constraint(s) in your formulation.

3-1- If your problem has two 2 objective functions then you can pass your formulation to the "triangle splitting method" (which is an exact method) embedded in the following julia package to solve it:

3-2- If your problem has more than two objective functions then you can pass your formulation to the following julia generic heuristic package to solve it:
