Maximizing Minimum Profit while Minimizing Maximum Regret

Dr. Meinolf Sellman shared a decision problem that deals with planning crop growth without knowing the weather. His solution is based on the proprietary multi-objective optimization that helps to find a rational compromise between maximizing the minimum profit and minimizing … Continue reading

Decision-Dominant Logic

Dr. Roger Moser: “We have entered the algorithmic age—an era where competitive advantage is defined less by the products you sell or the services you deliver, and more by the decisions your organization makes and how well it makes them. … Continue reading

Decision Modeling and Fairness

Could we achieve fairness in our automatic decision-making? This question was actively discussed in the presentation “How to make optimal decisions (that are unfair, biased and non-objective)” given by Dr. Guido Tack in May of 2024. While Guido used the … Continue reading

Big Decision Tables

Decision tables are the most popular decision modeling constructs but they have a tendency to grow with time or to use huge arrays of data from the very beginning. When decision tables have tens and even hundreds of thousands of … Continue reading
