Decision Model for Order Promotions

Our Jan-2018 Challenge deals with a popular business decision problem:  help merchants to define various promotions for their sales orders and to automatically decide which orders are eligible to which promotions. A simple example of promotion: reduce the total cost of the order by $3.50 if it contains at least 5 items 1108 and at least 4 items 2639. This challenge was generalized by M.Parish: Continue reading

Core DMN Components

DMN-ExecuteAccording to James Taylor, “The vast majority of the business logic in a decisioning system can be defined using the two core DMN components:

  • Decision Requirements Diagrams structure decision problems, break them into coherent pieces. They show where data is used and what knowledge assets (policies, regulations, best practices) are involved.
  • Decision tables specify the logic for most of the decisions on the diagram using simple constructs.”

It certainly leaves the most complex DMN components such as “boxed expressions” out of the DMN core. James even adds: “frankly most decision tables look and work the same even if they don’t support DMN yet.”  Agree? Disagree? What does constitute the DMN Core in your opinion?

Our tendency is to stress, analyse and act based on negative events. So use this tendency to the contrary with the rules of happiness“. You may find the rules here

Deep Learning Sharpens Views of Cells and Genes

Eyes are said to be the window to the soul—but researchers at Google see them as indicators of a person’s health. The technology giant is using deep learning to predict a person’s blood pressure, age and smoking status by analysing a photograph of their retina. Google’s computers glean clues from the arrangement of blood vessels—and a preliminary study suggests that the machines can use this information to predict whether someone is at risk of an impending heart attack.” Read more

Best Challenges/Solutions of 2017: Poll Results

We received 91 votes for our 2017 Community poll. The challenges/solutions which collected the most votes are presented in the following table:

As all votes were anonymous, it’s hard to tell how objective these results are: we do not know if voters selected certain decision models over others by actually comparing the models or by “voting for friends” with no comments. In 2018 we plan to select a small group of well-known DM experts, and ask them to compare all solutions for 2018 challenges and explain their reasons for selecting the winners.

If you have decision modeling problems to be published as new DM Challenges, please send them to
