OptaPlanner

A BPMN diagram models a Business Process. When the Business Process involves optimization at some step, OptaPlanner can help you quickly find an optimal solution. Now with Kogito, it is easier than ever before to integrate OptaPlanner into your BPMN diagrams! It so simple, that by the end of this blog, you will create a...

Now with Kogito, it is easier than ever before to integrate OptaPlanner into your BPMN ... [More] diagrams! It so simple, that by the end of this blog, you will create a Business Process for scheduling a flight in an airline from scratch using OptaPlanner, BPMN and Quarkus in 15 minutes. Project Setup Create a new folder to hold this project. Run the following command to create a new Quarkus project: mvn io.quarkus:quarkus-maven-plugin:1.4.1.Final:create \ -DprojectGroupId=com.company \ -DprojectArtifactId=airline-bpmn-optaplanner \ ...

Traditionally, to scale out with OptaPlanner, you had to learn DRL. No more. With the new Constraints Streams API, inspired by Java 8 Streams and SQL, you can now write your constraints in Java (or Kotlin or Scala) and still benefit from incremental ... [More] calculation.

Underneath, Constraints Streams (CS) still use the powerful Drools engine. We also still fully support score DRLs too. They are not deprecated. Let’s start with an example. In nurse rostering, to avoid assigning shifts to employee Ann, you would write this constraint in DRL: rule "Don't assign Ann" when Shift(getEmployee().getName() == "Ann") then ... [Less]

Many workplaces host a "Secret Santa", where each employee gets assigned a coworker whom they need to buy a present for. This fosters good relations between the employees and brings them closer together. But what about global companies, where ... [More] coworkers may be many miles apart? Ideally, we want employees who are further apart to give gifts to each other, since they are the ones who probably know the least about each other. Let’s optimize it with OptaPlanner! The Constraints One of the most obvious constraints is that everyone should get a gift. Or phrased a little differently: no one should get multiple gifts. Here is how one would create this... [Less]
