Stateful Loan Approval Process with AWS Lambda+EventBridge+SNS+SQS

At DecisionCAMP-2020 we had a lot of discussions about the orchestration of the decision services and how to invoke different decision services when states of the business objects change over time. One of the most popular orchestration technique is a Pub/Sub architecture with State machines. The Challenge “Dynamic Loan Approval” is an example of perpetually running decision-making applications which should be able to learn from already executed transactions and evaluate new facts as they become available. This post describes how we implemented this application utilizing OpenRules-based GUI connected to AWS Lambda, EventBridge, SNS, and SQS.

Notes from DecisionCAMP-2019

DecisionCAMP-2019 in beautiful Bolzano on Sep. 17-19 will go down in history as one of the most successful DecisionCAMPs. As usual, it was packed with interesting presentations and even more interesting formal and informal discussions. I’ve written my notes from this memorable event – read them here.

Stateful Decisioning and State Machines

Nowadays it’s not enough for decision-making applications to simply execute a complex rules-based transaction, forget about it, and wait for the next one. These applications frequently have to maintain states of the business objects they manage and and based on their states invoke different decision services. Orchestration of the decision services becomes a serious issue but different implementation techniques frequently utilize State machines. In this post we will use the DMCommunity Aug-2019 Challenge to demonstrate how it can be done.

Notes from DecisionCAMP-2018

This year DecisionCAMP was held in Luxembourg Sep 17-19 as a part of the Logic for AI Summit. It became an important event that attracted experts and practitioners in the business decision management from 14 countries. We had 54 official registrations and sometimes even more people were present in the auditorium. The representatives from almost all major BR&DM vendors and many well-known experts attended the event. As the chair of the event, I wrote the Notes from DecisionCAMP-2018 published at the DMCommunity.org blog.

OpenRules customer selected as worldwide Awards Finalist

A major California bank, facing looming regulatory deadlines, needed to develop a highly dynamic web application to support the bank’s complex customer account management processes. The integrated use of OpenRules’ s rule and rendering engines became the foundation for the successful and quick implementation. OpenRules nominated this real-world application to the first annual Business Rules Excellence Awards (BREA).  This success story was selected as a worldwide Finalist in the 2018 Business Rules Excellence Awards. This is a significant achievement for the Bank and OpenRules. The announcement of winning entries will take place on October 16.

OpenRules Presentations at DecisionCAMP and LuxLogAI-2018

OpenRules was well presented at the major technical business decision management event DecisionCAMP-2018. Here are the presentations directly related to OpenRules:

• Goal-Oriented Business Decision Modeling, Jacob Feldman (OpenRules)
• Automatic judgment of decision authority using OpenRules, Yoshihito Nakayama (Intra-Mart)
• Decision Modeling at AXA CH, Wilfried Kurth (AXA CH)

I also published a paper “Building and Analyzing Goal-Oriented Decision Models” at the Proceedings of the RuleML+RR 2018 Challenge – it explains our goal-oriented approach to decision modeling using a Credit Card Application decision model. In my closing notes I tried to demonstrate how a smarter decision engine can simplify decision modeling using concrete examples from DMCommunity.org challenges. After considering different decision modeling approaches, we will add these capabilities to standard OpenRules features.

Decision Automation and Explanations

Prof. Gene Freuder wrote a position paper “Complete Explanations” for The Second Workshop on Progress Towards the Holy Grail that will be held on Aug 27, 2018 during CP 2018 in Lille, France. Gene writes: “As AI becomes more ubiquitous there is a renewed interest in computers being able to provide explanations, and the European GPDR provides special impetus.” Geen’s paper concentrates on constraint satisfaction problems (CSPs), but, as I’d shown in my 2016 paper, we may consider a decision model as a CSP, and everything Gene is talking about directly applies to business decision modeling.

OpenRules will Present and Exhibit at BBC-2018 in November

Happy 15th Birthday, OpenRules!

Today is exactly 15 years since OpenRules, Inc. was incorporated on Feb. 24, 2003. It’s a quite serious milestone, so I decided to write a few words for this occasion. A year ago, I described a brief history of our company and key factors that made it successful. 2018 was an extremely successful year for OpenRules as well: we improved the product and many major corporations became our new customers. But in this post I want to look to the future and to share some of our upcoming and long term plans.

DecisionCAMP 2016

Last year the organizers of the DecisionCAMP (including myself) were not able to organize this very popular event that started in 2008 (see the history below).

Resolving Conflicts among Business Rules

Contradictory business rules occur in normal business situations, and maintaining rules with exceptions is a very typical example of rule conflicts. Is it possible to automatically resolve such conflicts?

Learning Business Rules from Data at RuleML-2014

OpenRules in Japan

Dr. Feldman and Mr. Nakayama, CEO at Intra-Mart

I’ve just returned from my first ever trip to Japan. I am coming back home to the US with very bright impressions of the Japanese culture and people. I was especially impressed by the deep respect and high professionalism with which people in Japan perform their jobs independently of how small or important those jobs are. I deeply appreciate the friendliness and readiness to help from people on the streets of Tokyo and Kyoto that I have not seen for a while.

This visit was organized by our Japanese partner NTT Data Intra-Mart.

Upcoming Events
