JAva SimuLATION - JalaTion

Welcome to JalaTion, the Java-based system for Simulation, Optimization and Analytics.

This system, coded in Java, will support multi-paradigm simulation modeling including 'tableau', 'event', 'process', 'dynamics', 'dynamics_pde', 'activity' and 'state' oriented models. It is a subproject of the ScalaTion project. Currently much of the funcationality of ScalaTion is missing.

Java is a modern object-oriented language that is well-suited for developing simulation engines. JalaTion will also support optimization and analytics as they nowadays go hand-in-hand with simulation modeling. Some of the algorithms come in both sequential and parallel versions.

The JalaTion 1.1 version works with Java 8 (some minor code changes may be required for Java 7).

Please read the LICENSE file (an MIT style license).

Installation Instructions

1. Download one of the following two files

2. Untar or unzip the file

3. Export the SCALATION_CLASSES environment variable to point at class files

Ideally, put the export in one of your dot files (e.g., .profile or .bashrc).

4. To re-build the JalaTion system, type the first command

The Simple Build Tool sbt is the easiest way to build JalaTion 1.1.

Source packages are in the src/main/java directory, class files are in the target directory, and documentation files are in the docj directory.

5. Run apps (e.g., for process oriented simulation in Bank.java)

The 'jscar' shell script works for Linux, Unix and Mac. Use 'jscar.bat' for Windows.

6. Run src test code (e.g., for Regression in scalation.analytics)

To develop using an IDE use for example Eclipse or NetBeans.
