But we also recognize a paradox: the more capabilities a platform provides, the harder it can be for a new user to know where to start. Our more than twenty years of experience has taught us something important. Many of our current customers started their…https://openrules.blog/2026/09/17/openrules-com-%e2%86%92-openrules-ai/https://openrules.blog/2026/09/17/openrules-com-%e2%86%92-openrules-ai/Thu, 17 Sep 2026 15:37:24 GMTAfter 23 years in business, our website, OpenRules.com, has accumulated a lot of material, and it is not always easy for first-time visitors to quickly find what matters to them. So, we decided to take advantage of the latest AI capabilities to give OpenRules.com a modern makeover as OpenRules.ai.

The article describes the evolution of this idea in […]https://openrules.blog/2026/09/05/notes-from-decisioncamp-2026/https://openrules.blog/2026/09/05/notes-from-decisioncamp-2026/Sat, 05 Sep 2026 17:01:41 GMTDecisionCAMP 2026 went into history a week ago. From August 25 to 28, we had four productive days filled with interesting presentations and lively discussions. All presentation slides and recordings are available in the Program or directly on our YouTube Channel. Many attendees of DecisionCAMP 2026 tell me it was a very informative and successful […]https://openrules.blog/2026/09/03/announcing-decisioncamp-2027/https://openrules.blog/2026/09/03/announcing-decisioncamp-2027/Thu, 03 Sep 2026 16:14:45 GMTFollowing the very successful DecisionCAMP 2026, we are pleased to announce DecisionCAMP 2027, which will take place September 14–16, 2027.

Representing and maintaining such rules becomes even more challenging when they conflict with each other and new rules need to be added — at which point a traditional rule-based approach begins to break down. With this in […]https://openrules.blog/2026/04/13/ai-friendly-decision-services/https://openrules.blog/2026/04/13/ai-friendly-decision-services/Mon, 13 Apr 2026 15:09:59 GMTLLMs aren’t decision-makers — at least not yet. But they’ve proven to be remarkably effective translators between natural language and domain-specific languages, unlocking access to decision services built on traditional rule engines, optimization solvers, and machine learning tools. Naturally, decision intelligence platforms have followed suit, providing mechanisms to turn decision models into…https://openrules.blog/2026/04/05/agentic-medical-services/https://openrules.blog/2026/04/05/agentic-medical-services/Sun, 05 Apr 2026 17:39:56 GMTDMCommunity.org has posted a new April 2026 Challenge that aims to explore how LLMs orchestrate rule-based decision services. It describes three loosely coupled medical services that an LLM can use to help a physician determine the appropriate therapy for a patient with Acute Sinusitis.

In both cases, a new layer of abstraction shifts professionals away from manual work toward modeling, design, and decision-making. So, I asked Claude.ai about this analogy. Here is the answer: “The parallel […]https://openrules.blog/2026/02/25/making-a-good-burger-with-decision-playground/https://openrules.blog/2026/02/25/making-a-good-burger-with-decision-playground/Wed, 25 Feb 2026 21:57:13 GMTSee how OpenRules Decision Playground can help to make a preferred burger using different ingredients while minimizing the total fat, calories, or cost: https://openrulesdecisionmanager.com/decision-playground-make-a-good-burger/https://openrules.blog/2026/02/25/select-website-features-with-decision-playground/https://openrules.blog/2026/02/25/select-website-features-with-decision-playground/Wed, 25 Feb 2026 21:49:34 GMTSee how OpenRules Decision Playground can help a freelance web designer to choose different combinations of features while maximizing the total value of these features subject to a limited budget: https://openrulesdecisionmanager.com/decision-playground-website-features/https://openrules.blog/2026/02/25/select-preffered-loan-with-decision-playground/https://openrules.blog/2026/02/25/select-preffered-loan-with-decision-playground/Wed, 25 Feb 2026 21:34:50 GMTSee how OpenRules Decision Playground can serve as a self-service graphical interface that helps the customer select the most appropriate loan conditions: https://openrulesdecisionmanager.com/graphical-decision-modeling/decision-playground/selecting-loan/https://openrules.blog/2026/02/25/making-a-good-production-decision-with-decision-playground/https://openrules.blog/2026/02/25/making-a-good-production-decision-with-decision-playground/Wed, 25 Feb 2026 11:30:00 GMTSee how OpenRules Decision Playground can help a manufacturer evaluate various production decisions and select the most suitable ones — taking into account long-term resource availability and uncertain future demand. https://openrulesdecisionmanager.com/decision-playground-inside-outside-production/https://openrules.blog/2026/02/24/from-solvers-to-decision-factories/https://openrules.blog/2026/02/24/from-solvers-to-decision-factories/Tue, 24 Feb 2026 23:19:22 GMTAfter reading the new book "The Decision Factory", I posted an article with this title on LinkedIn.
