The Discrete Event System, University of Michigan and Mount Allison University, or DESUMA, is a software and educational tool used to build, analyze and control models of Discrete Event Systems (DES) as finite-state automata (FSA). It consists of the integration between the UMDES library (a set of commands for DES operations), developed at the University of Michigan under [http://web.eecs.umich.edu/~stephane/ Prof. Stephane Lafortune], and the graphical environment for visualizing discrete event systems, called GIDDES (Graphical Interface for the Design of Discrete Event Systems), developed at Mount Allison University under [http://www.mta.ca/~lricker/ Prof. Laurie Ricker]. DESUMA allows the user to perform a variety of manipulations of discrete event systems modeled by FSA related to model-building, fault diagnosis, verification, control under full and partial observation, and decentralized control.

DESUMA2 is the latest software version made public in 2014. Notable changes from the previous DESUMA version include the FSA layout being done using J-Graph instead of GraphViz due to compatibility problems with the latest JAVA versions. Several GUI related enhancements were made, and known bugs in the underlying UMDES commands were fixed.

DESUMA2 is the new version of DESUMA made public in 2013. The most significant change from the previous versions of DESUMA is that the layout of FSA is done using J-Graph instead of GraphViz. This change was motivated by compatibility problems of GraphViz with newer versions of Java. In addition, several enhancements were made in DESUMA2 related to the GUI part, and known bugs in the underlying UMDS commands were fixed. Please note that the UMDES commands are embedded within DESUMA2. However, it is also possible to run UMDES commands from the command line; see UMDES section in that regard.

UMDES is a library of C routines for creating and manipulating discrete event systems modeled as FSA. In particular, many of the algorithms for the theory of supervisory control and from the theory of diagnosability of DES are implemented in UMDES. While the main commands in UMDES are embedded within DESUMA and DESUMA2, users may still wish to run these commands from the command line. For this reason, we continue to provide compiled versions of the UMDES commands for separate download.

A slight source of confusion is that the names of the UMDES executables do not always exactly match the names of the same commands in the DESUMA and DESUMA2 menus for UMDES. Please refer to the links below for more information regarding UMDES commands, when used from the command line.

DESUMA 1.5.4 interface for Windows

The Discrete Event System, University of Michigan and Mount Allison University, or DESUMA, is a software and educational tool used to build, analyze and control models of Discrete Event Systems (DES) as finite-state automata (FSA). It consists of the integration between the UMDES library (a set of commands for DES operations), developed at the University of Michigan under Prof. Stephane Lafortune, and the graphical environment for visualizing discrete event systems, called GIDDES (Graphical Interface for the Design of Discrete Event Systems), developed at Mount Allison University under Prof. Laurie Ricker. DESUMA allows the user to perform a variety of manipulations of discrete event systems modeled by FSA related to model-building, fault diagnosis, verification, control under full and partial observation, and decentralized control.

Continuous development of DESUMA is a joint effort between Mount Allison University (Prof. Ricker and her colleagues) and University of Michigan (Prof. Lafortune and his colleagues).

Note: UMDES commands are embedded within the DESUMA software. However, running commands from the command line is also possible. See UMDES section for more.


DESUMA2

DESUMA 2.0.0 interface for Windows

DESUMA2 is the latest software version made public in 2014. Notable changes from the previous DESUMA version include the FSA layout being done using J-Graph instead of GraphViz due to compatibility problems with the latest JAVA versions. Several GUI related enhancements were made, and known bugs in the underlying UMDES commands were fixed.
