This dataset requires Rodin and Java to open the files:

RODIN
-----
We provide Rodin installations containing required plugins for the major OS
You need Java - see note below about Java  versions.
You can create a new Rodin installation for your platform as follows:
download Rodin from sourceforge https://sourceforge.net/projects/rodin-b-sharp/
(we used Rodin 3.4 but you may be able to use a later version if available)
unzip and Start Rodin and from inside Rodin
(you will need to add the prototypes update site provided, as this contains unreleased versions of some of the plug-ins - the University of Southampton ones with a long qualifier in the version number). Other plugins are available on the following pre-configured update sites: AtelierB, ProB, Rodin update site)
in preferences - Event-B - Sequent prover:-
1) change the Meta Prover to remove newPP and add ML above PP
2) import the profile proverProfile and set it as the tactic profile to be used for Auto-tactics


JAVA
-----
NOTE:
Rodin 3.4 is based on Eclipse 4.7
A java JVM is needed to run Rodin. 
A late release of Java 1.8 (i.e. service number greater than 130) is preferable and should run Rodin without any changes to configuration
Java 1.9 can work if you change the configuration file rodin.ini to add the following
-vmargs
--add-modules=ALL-SYSTEM
Other Java versions may work but you may need to web-search for other config settings.


This dataset contains:Event-B model of a two-level hierarchical scheduling system with local resource sharing managed by time division multiplexing global scheduler and two alternative local schedulers refined by the nondeterministic queue-based scheduling policy. Developed to support a special issue of ABZ2018 in Science of Computer Programming.


The figures are as follows:

Fig. 1 Improvement of Current Refinement Structure
Fig. 3 Two-level Hierarchical Scheduling System
Fig. 10 Time diagram of timing properties’ refinement with the scheduling framework
