Red Hat Decision Manager

A cloud-native approach to building business rules and decision services

Agile rule development with Decision Manager

Red Hat Decision Manager is a fast, lightweight, cloud-native business rules and decision management platform. The platform enables developers and other personas to develop rules and decision-driven applications, services, and systems in an agile way. Decision Manager also provides a versatile set of decision capabilities, including a rules engine based on the PHREAK algorithm (an evolution of the well-known Rete algorithm), DMN v1.3 compliance, support for intelligent decisions that use PMML, and a complex event processing engine.

The Decision Manager approach to building decision services

Kogito-based decision applications

Learn how to use the brand new authoring and execution capabilities of Decision Manager based on Kogito. You'll create supersonic, subatomic rules and decision services based on Quarkus, and you'll experience increased efficiency through Kogito code-generation and Quarkus hot-reload features.

Drools-based rules engine

Leveraging the power of Drools, the highly popular and de-facto open source rules engine, Decision Manager delivers an enterprise-class, high performant, and scalable rules execution engine. The PHREAK reasoning algorithm provides a runtime that easily scales to hundreds of thousands of rules in a single rules execution environment.

Decision Model and Notation (DMN)

DMN is a relatively new standard managed by the Object Management Group (OMG), the organization behind BPMN. Decision Manager is the first open-source DMN v1.3 runtime that supports the full FEEL Compliance Level 3 of the DMN specification. DMN simplifies the process model by removing the rules and decisions from the process and creating the optimal outcome.

Business Optimizer

Business Optimizer (aka OptaPlanner) provides an easy-to-use framework to build solvers in plain old Java that find optimized solutions to these problems. Building solvers puts the power of AI in the hands of Java developers. Packed with ready-to-use templates and reference applications, Decision Manager provides a platform to automate almost every type of planning problem.

Agile development

Decision Manager provides tools that target all users. The VSCode plugin allows developers to author decisions using the DMN specification and to test it using an intuitive test scenario simulation tool. Since the service is built on top of technologies like Git and Maven, it enables developers to easily integrate Decision Manager with existing CI/CD technologies and methodologies built on Tekton Pipelines, Jenkins, SonarQube, and OpenShift.

Cloud-native

Cloud-native development focuses on the creation of lightweight, stateless, microservices, providing powerful APIs deployed in container environments using development practices based on DevOps and Continuous Delivery engineering methodologies. Decision Manager is the first business rules and decision management platform that fully fits into the cloud-native paradigm.

Decision Manager and the KIE community

Using Decision Manager is a great way to build real-world enterprise applications based on the latest technologies. If you find something that needs fixing or have a new feature to suggest, get involved with the Kie Community. That's where you can give feedback, improve the docs, review code, and discuss and propose new features when they’re needed. Answering user questions and taking part in development discussions are also great ways to build your reputation for collaboration and expertise in your field.

No matter what skill level you've reached, contributing to Decision Manager can be very rewarding and a great learning experience. You’ll meet lots of smart, passionate developers who are all driven to support open source, plus you don’t have to be an expert to get involved and it doesn’t have to take a lot of time.

Kogito

Kogito is designed specifically to excel in a hybrid cloud environment and to be adaptable to your domain and tooling needs. The core objective is to help you mold a set of business processes and decisions into your own domain-specific, cloud-native set of services

OptaPlanner

OptaPlanner delivers efficiency, which improves service quality and reduces costs. Planning problems are challenging and require sophisticated AI in the form of heuristic optimization algorithms to find the optimal solution.

Drools

Drools is open source and provides open and extensible APIs, which allow the platform to be utilized in a vast array of environments from embedded, IoT stream processing based on Vert.x to microservices-based decision services running in Kubernetes-based environments like Red Hat OpenShift.

RHDM use cases

Credit-scoring - Easily validate the business rules you incorporate into your decision services, so your technical teams can integrate the credit-scoring validations with the services and applications in their ecosystem.

Fraud detection - If you detect suspicious transactions, you can utilize a combination of complex event processing and AI/ML to quickly determine if those transactions are fraudulent.

Premium calculation - The calculation of a premium is dependent on a set of rules. Decision Manager employs high-performing algorithms to calculate the value of the premium for each specific scenario.

Law and regulatory compliance - Use decisions and rules to help ensure that your organization is compliant with laws and regulations and deliver regulation-compliant solutions with data security and integrity.
