OptaPlanner

The more smart devices are connected to the internet, the more in need of smarter systems we are. These systems should monitor, automate and maintain these devices in a robust and efficient way. In this demo, we simulate a factory plant containing multiple pieces of machinery. The system we built monitors these...

The goals of the RH Summit 2019 Keynote Demo was showing multiple Red Hat products working together on OpenShift, demonstrating how OptaPlanner can schedule mechanics repair machines in an ...

The more smart devices are connected to the internet, the more in need of smarter systems we are. These systems should monitor, automate and maintain these devices in a robust and efficient way. In this demo, we simulate a factory plant containing ... [More] multiple pieces of machinery. The system we built monitors these machines and automatically dispatches mechanics to fix them in a smart way. To learn more about the use case and challenges, read Part 1 by Geoffrey. Overall system architecture To simulate damage source, we created a mobile app whose users signalize damage to machines by shaking their phones. The shaking data is sent to a... [Less]

Task Assignment KJAR KJAR or "Knowledge JAR" is a standard JAR file that has some extra files included (at least a META-INF/kmodule.xml file). You will build Task Assignment Service as a KJAR. Note In order to build the KJAR, the project’s pom.xml needs to have a entry and contains kie-maven-plugin. Problem Description Assign each task to a spot in an employee’s... [Less]

Java 11 was released some time ago, although the majority of developers stay on Java 8. Let’s see which one of them is faster for OptaPlanner. The best way to find out is of course running OptaPlanner benchmarks. This article is a follow up on our similar article for Java 8. Benchmark methodology To run...
