New version : GRIF 2015

SATODEV and TOTAL are pleased to announce the 2015 version of GRIF and its 10 modules (Petri, Petro, BStock, Tree, BFiab, ETree, SIL, Bool, Reseda, Markov).

The improvements that you will find in each module are:

  • Ability to be started with a command-line (to be integrated in other tools)
  • Better display configuration for every object
  • Description on parameters and variables
  • Copy/paste has been improved again with new options to link data
  • A new window displaying errors and warnings helps you find mistakes
  • A new PDF printing including more content and fully customizable.

PetroThe Petro module has evolved a lot, the main improvements (among hundreds) are:

  • A new table for resources (spare parts and maintenance crew)
  • Condition for repairing and for maintenance
  • Importing from BStoK and BFiab (in order to add resource management to your RBD)
  • A new library for templates
  • Undetected failure handling
  • K out of N connector with K variable

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.

Moca-RP is now available in 13.24 version and Albizia in 0.5d version.

This new version can be download on download page.
