Find what's going to happen next in your business

As Abraham Lincoln said: "The best way to predict your future is to create it"

Can you find the best solution?

Looking for solutions that will help you gain insight in the future and recommend the best way forward? Give it your best try with this brain teaser. It took IBM – CPLEX 5 seconds to find the correct answer. Can you discover it? Give us your answer or your best guess and stand a chance to win the grand prize. 

Decision Optimization Brain Teaser: What is the maximum ROI? 


Use each number between  0 -> 9 only once, to replace the letters in the sentence.

(for example C=1, U=3, W=4, ….)

The sum must be correct, each number must be used EXACTLY once. With the correct sum, there are many solutions. But which solution has the highest value for the letters R, O and I?

Target: Maximize the value of ROI. There is only 1 correct maximum value for ROI. What number (like 123) corresponds to the letters ROI?

Join our competition and WIN an all-expenses paid trip to attend our next Cubewise TM1 and Planning Analytics User conference ANYWHERE in the world (Europe, US, Asia, Australia). 


To be eligible for the grand prize, you need to submit correct answers to all three the questions on these 3 webpages: “What is our plan”“What happened and why”, and “What will happen next”.

Employees, partners, officers, and contractors of Cubewise and IBM are not eligible to participate in this competition.

The maximum number of entries to a competition per person is one.

Competition ends 18th of January 2021. Out of all participants with 3 correct answers, we will draw 1 winner.

This competition is only valid in the following countries: Africa, Australia, Belgium, Canada, China, Denmark, Finland, France, Greece, Hong Kong, Ireland, Italy, Japan, Luxembourg, Malaysia, Netherlands, New Zealand, Norway, Poland, Portugal, Singapore, Spain, Sweden, Taiwan, Thailand, Turkey, Ukraine, United Kingdom, United States of America.

The name of the game here is accuracy, because accuracy = money. 

Accurate predictions means we have the right products available at the right time, we can lower the inventory or negotiate better terms, less stock means less discounts, better price decisions, having the appropriate staffing when we need it where we need it, streamlining the production and distribution process to cater for the forecasted quantities.

Data Science and statistical forecasting 

We ventured into the realm of data-science, and the type of advanced modelling these tools are capable off, surpass what we can handle as a human. Having an accurate calculation model, based on a set of drivers, impacting each other and coming up with a suggested outcome, has an immediate return on investment.

TM1, based on an underlying data-science model, brings harmony to the word. Drivers will be visualized in TM1, and choices can be made to enter the drivers manually by the users, or use a statistical forecast for them, or a combination of both. The power of the automation will remove the burden of manual input and the limitation of humans being able to handle large data volumes while understanding the interaction between drivers.

In this type of setup we tend to see a cycle of progressive insight. Realizing the correlation between certain drivers and the results we are perceiving, can show us that maybe certain drivers aren’t as important as we thought they were, or they have changed over time. The data-science based modeling is an iterative process, where the actual outcomes will feed back into the calculation model, to refine it, change the weighting of drivers, and increase the accuracy over time and in view of an ever changing world.

Decision Optimization

‘Decision Optimization’ Considering we have a solid plan in place and we have an accurate vision of the future, there is only one thing left to do: execute it ! The reality is that we need to execute this plan in an environment that is full of constraints, conflicting targets, and thousands of options to consider. Decision Optimization focuses on what route is best to follow within the constraints we have, given the targets we set in a specific priority. 

Today, CPLEX is the best performing solution to tackle these mathematical algorithm challenges. As a bonus, it integrates perfectly with TM1.
