The software available from this page has been release under the GNU General Public license (GPL), version 2. For specific details of the terms of the GPL, please read the license here. For more information on the GPL, please see the Free Software Foundation.

The general idea is that the GPL allows you to take a copy of the software and pretty much do what you want with it. You are also given access to the source code. You are free to use the source code to make a new program, but the new program must also be released under the GPL. You can include parts or all of the program in your own program, as long as you distribute your program under the GPL or a compatible license.

  • DESpot is a new discrete-event system (DES) software research tool. It supports both flat projects (collection of plant and supervisor DES), and Hierarchical Interface-Based Supervisory Control (HISC) projects. For more information, see here.

  • Online Research Resource Database (ORRD): Provides the php/MySQL based software to set up a community based, searchable website for bibliographical information of research related resources such as papers/thesis/books/tech reports and so on. For an example, see the DES ORRD web site. You can download the source code here. Note, the software was designed to be deployed on a unix/linux server, but probably could be easily adapted for use on a windows server.

    The software for the ORRD was originally developed by Ayesha Kashif as part of her M.Eng (software) project. Additional bug fixes and extensions were then made by the Brian Hogg Consulting firm.
