New Version of Mercury Tool Available!


The version 5.3.1 of Mercury has been released.


Dear Colleagues,

We are pleased to announce that version 5.3.1 of the Mercury tool has been released to the industry and academic community.

This new version fixes several bugs found in previous versions.

If you are a Mercury user, we strongly recommend getting the new version.

We hope you will enjoy it. If you have any suggestions or find any bugs, please report them to us.

If you do not know the tool yet and want to try it, please go to www.modcs.org and go to “Downloads” and “Mercury Tool”.

There, you will get a form, sign it, and download the tool.

What’s new in Mercury?

Below, we describe the most important features and enhancements of version 5.3.1:
    1. Usability
      1. Enlargement of the internal area of some components (places, transitions, and states) used to connect arcs to other components.
    2. Placement of graph elements
      1. Fixed an issue that caused elements (SPN, CTMC, and DTMC) to be placed in different locations than those selected by the user when zooming.
    3. DTMC module
      1. Fixed an issue in the DTMC module where transition probabilities between states were miscalculated when using expressions with variables.
    4. MTTA simulation
      1. Fixed an issue with MTTA evaluation by simulation when the SPN model contains arcs with expressions.
    5. Exporting CTMCs to Mathematica
      1. Fixed a bug that incorrectly assigned transitions between states when exporting CTMCs to Mathematica.
    6. Other minor improvements and bug fixes.

What is the Mercury tool used for?

Mercury enables a range of models to be created and evaluated for supporting performance and dependability evaluations, such as reliability block diagrams (RBDs), dynamic RBDs (DRBDs), fault trees (FTs), energy flow models (EFMs), stochastic Petri nets (SPNs), and continuous and discrete-time Markov chains (CTMCs and DTMCs).

The tool has been cited in more than 140 scientific publications and used in over 18 countries worldwide.
Important notes on upgrading
Java 8 (1.8) is the recommended version of Java for running Mercury 5.3.1. Java 9 introduces the Java Platform Module System (JPMS), a new architectural design to which the tool has not yet been ported. We deliver Mercury 5.3.1 with the appropriate Java SE runtime environment (JRE) for Windows and *NIX systems. We also release the tool without the JRE, which is suitable for other environments. If you want to download Mercury without the JRE, you can find the recommended JRE
