Simtool is a program for process-based discrete event simulation written in Java. Version 1.0 was developed in the winter semester 2001/2002 in the Wirtschaftsinformatik-Praktikum of the Institut für Wirtschaftswissenschaften, Abteilung Allgemeine Betriebswirtschaftslehre, Wirtschaftsinformatik und Informationsmanagement of the TU Braunschweig to be included in a virtual learning environment.
Version 2.0 was created as a part of the diploma thesis: A Script-driven Simulation Tool as an Improvement to the Education in Web-based Virtual Learning Environments. This document is available for download at the documentation section.
Version 2.1 was the first release of SimTool via Sourceforge.net. The most important change was packing everything into a signed jar file so that the user does not have to deal with all the security permissions.
An additional simulation component was created by Sandra Bangewitz and Manuela Bernhardt.
We decided to release Simtool under the terms of the GPL, in order to enable other students to continue the development of Simtool, while making sure, that this work stays free for everyone who wants to use and/or improve it. In order to allow the integration of Simtool in the virtual learning environment, we grant the additional right to include the Simtool in such an environment without the requirement to release the whole learning environment GPL'ed (see licence).
Simtool 2.1 was developed and is copyright (C) 2003 by Björn Paschilk and Torsten Klie, TU Braunschweig. The previous version Simtool 2.0 was developed and is copyright (C) 2002 by Torsten Klie and Christoph Schalong. The first version Simtool 1.0 was developed by Oleg Dück, Marco Hellmann, Jörg Hevers, Torsten Klie, Florian Maul, Nils Oppermann Björn Rösemeier and Christoph Schalong.

In addition, as a special exception, it is allowed to integrate Simtool into avirtual learning environment and distribute the virtual learning environment as a whole, without the requirement of releasing the whole virtual learning environment under the terms of the GPL, as it would normally be required by the GPL. In case of the integration of Simtool into a virtual learning environment, the GPL shall only cover the Simtool-part of it.
