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.

Ability to add/remove rows in "Input Data" tables in Model Builder

Use case: I duplicate a scenario in the "Scenarios" panel. The scenario I'd like to test involves adding/removing one data point, e.g. adding a new machine in the predictive maintenance model or taking that machine out of service by removing it. ...

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...

Improve constraint priority attachment in OPL

Actually we have to use OPL script to attach a relaxation priority to a constraint. It will be easier to attach this priority at the creation of the constraint. Reason is that a constraint tupleset can easily include a priority field:tuple rvConst...

Piecewise function with input as coordinate (x,y) of curve's points

the actual piecewise function in OPL takes as input abscissas and vector coefficient to construct the function.Many time people have user have the (x;y) coordinate. to do that you need to write OPL code to find the vector coefficient.Would be grea...

Make CP cumulFunction and expressions accept float instead of int

cumulFunction and expressions currently only allow the resource usage to be int which is not useful for all resource types. Whilst a workaround of multiplying the int by a large number to approximate the float is possible there are limitations and...

OPL port for z/OS

We are looking at CPLEX on zOS.Today, only compiling a C++ program can be used to drive CPLEX on the z platform. It would be much easier to be able to inject OPL directly in (concert, part of ) CPLEX for z/OS.

Improve OPL Interfaces by providing dynamically typed API and a “façade” compatible with the .NET framework

Using OPL interface in .Net is cumbersome. Manipulate data elements object and result is far from being trivial.By example, instantiate an int look like that:OplDataSource dataSource = new MyCustomDataSource(oplF);internal class MyCustomDataSource...

Improve OPL Interfaces by providing field access infer by using the OPL model schema

Modify coefficient, adding variable, iterate on tupleset, modifiing dataElements and almost all operation in the OPL interface are really counter intuitive. Object uses by OPL are not directly compatible with the framework object. Ituple!= Tuple. ...
