IBM Data and AI Ideas Portal for Customers

Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Bring MATLAB interface back for CPLEX

Please bring back the MATLAB interface for CPLEX. We rely heavily on this feature since toolboxes we use are Matlab exclusive.

IBM Z Common Data Provider template for the User Define SMF Record Type 249 cut by DVM

The customer is using IBM Z Common Data Provider (zCDP) to stream SMF records in real-time to their Splunk. zCDP provides policies for all the non user define SMF records, the SMF249 is a user define record, hence zCDP can't reference o it, so it ...

Interface between CPLEX and FORTRAN

Since FORTRAN is one of the TOP20 programming languages in the TIOBE index (, I suggest that IBM create mixed-integer linear programming models with CPLEX and FORTRAN. I have not found a library similar to Conce...

Replacement for DB Link to allow sensible database access from OPL

DB Link functionality was removed from version 12.7 and this prevents the sensible accessing of databases from OPL by removing the availability of DBConnection, DBRead, DBUpdate and DBExecute.Whilst there were various issues and bugs with the data...

OPL model generation with multithreating

the OPL model generation uses only 1 core and it takes time.with a pre analysis of the model it could be possible to parallelize some of the model generation.

OPL interface for Matlab

Would be great to have not only a Matlab interface to CPLEX, but to OPL as well. It would facilitate. model deisgn (.mod) using OPL (way easier than working directly with CPLEX. model modification, re-run, post/pre-processing computations using a ...

WML multiprocessing support

Multiprocessing using Pythons multiprocesing library works with Notebooks in Watson Studio, but not for deployed WML models. Multiprocessing for DOCPLEX MILP models can significantly reduce time and resources used for solving a set of several mode...

read solution from cpo file

For CP-Optimizer, it would be great to have the ability to read a given solution from a file and pass it to a cpo model as a starting point and also enable to check this solution feasibility

Run optimization solver invocations in parallel

Extract from SAS PROC OPTMODEL COFOR new feature:Be able to run optimization solver invocations in parallel, in iterations of a concurrent FOR loop that is specified using the COFOR statement. The COFOR statement operates in the same manner as the...

Calling external .NET code from OPL

Offers a way to interact with external code written in .NET from OPL.This feature would allow us to:• write a complex dedicated OR algorithm (such as a shortest path or flow algorithm) to be used as one step of a decomposed application• connect yo...
