New version : GRIF 2014

Dear users,

a new version of GRIF-Workshop is now available. This version brings a great number of evolutions for all the modules, the main upgrades are:
GRIF (every module)

  • GRIF use Java7 and the new Sentinel LDK protection system.
  • Zooming is now made on selected objects, and zoom factor can be specific to each page.
  • Data can be merged with a right-click in data tables.
  • In bloc module, a preview is displayed on sub-system blocks.
  • Copy/Paste has be improved to do a different renaming for each type of data.
  • The sort in data table is now Alpha-numerical, une « var11 » won’t be after « var2 » but after « var10 ».
  • Overall performace improvements.

Bool (for each module of boolean package)

  • A new “distribution law” : Markov-graph. Describe the behavior of a component with a MArkov-graph made with markov module.
  • .sil and .jetr import in Bool module.
  • Files coming from KB3 software (developed by EDF) can now be opened in Tree module.
  • In “probabilities et fréquencies” tab, computed values are: U(t) A(t) W(t) Lambda(t) R(t) F(t).
  • A new computation cache prevents from time consuming recomputation.
  • Lambda used for common cause failures is not necessarily the maximum lambda of impacted component, it can be chosen among: aritmetical average, quadratical average, geometrical average (PDS method).
  • Event-Tree module can display either maximum or average risk in risk matrix.

Petri12 (Simulation package)

  • Transition configuration can be copied from another transition.
  • A new Weibull law with different parameters.
  • Right click on an empty place lets you add a place-shortcut.
  • Automatic layout is possible locally. Moreover « Ctrl » + left-click with place-tool or transition-transition adds next node with a link and do an automatic layout.
  • Places and transitions can be selected during simulation in order to zoom on it.
  • Arcs weight can be modified with a right-click on several selected arcs.
  • Interactiv-simulation starting time has been divided by 80. Loading time before computation has been divided by 80.
  • New fast-forward in interactiv siumulation, that goes 60 times faster than before.
  • New modulo (%) compatible with float-number. At time t=49.5, time()%25 is equal to 1.5 and not 1 (value in 2013 version).

SIL (Boolean)

  • Sytems with several loops can be added.
  • 16 sensor-chanels can be created.
  • The D configuration became A configuration, and the trip limit can be configured manually.
  • Spurious trip computation.
  • Lambda used for common cause failures is not necessarily the maximum lambda of impacted component, it can be chosen among: aritmetical average, quadratical average, geometrical average (PDS method).


Petro

  • A lot of new behaviors have been added for blocks and connectors.
  • Performance improvements.
  • New data-tables to configure blocks.
  • Sub-systems with their own capacity.
  • Interactiv-simulation.
