Reliability Workbench 14
The new features in Reliability Workbench 14 are:
- Import/Export to Excel has been speeded up for very large Excel files
- Excel import and export now handles multi-line text fields. Excel 2007 special identifiers _x000D_ are also removed on import
- Plugins may now perform analyses so long as the appropriate module licence is available
- The parts library and report generator now use SQL Express for both 32-bit and 64-bit versions
- The Help system now uses the default browser to display topic information.
- A new method has been added to the DLL allowing prediction calculations to be performed
- Multiple derating definitions may now be provided for the same prediction category and sub-category to allow for multiple derating parameters (e.g. current and voltage stress)
- Additional testability parameters for fault isolation have been added to the FMECA module.
- IEC 61508 parameters are now transferred when converting a FMECA to a fault tree or RBD. The failure model created will now match the default failure model set in project options
- Users may now choose to enter failure rates for component failure modes directly rather than assign an apportionment percentage. This is achieved by deselecting the ‘Use apportionment to assign failure mode rates’ project option.
- Failure rate units are now displayed in the Block and Mode dialogs.
RBD, Fault Tree and Event Tree Modules
- The RBD module now has an append facility allowing users to append systems blocks from external projects. Blocks are only appended if there is a component block with the same ID in the target project.
- Bitmaps may now be stored inside a project
- The Sequential Model failure model type has been extended for fault tree and RBD analysis. The extended model enables accurate averaging calculations to be performed taking into account sequencing. The model also provides for modelling revealed double and triple latent (dormant) failures that are revealed before a flight (for aircraft applications), a journey for (automotive and rail applications) or a mission
- PDF files generated from rbd, fault tree and event tree diagrams now have page links allowing users to click on a page reference and move to that page. Fault tree event paste special no longer opens the tree control event node
- RBD paste special operations now display a Paste Special dialog if more than one block is being copied in the current project. This dialog allows users to choose system and component blocks that are not to be renamed when copied.
- The SSA module now allows users to enter up to 3 effects for each failure. Effects and effect types are now organised into 3 categories. The user may change the description of each effect category in the project options dialog
- A paste special function has been added to the SSA module allowing sub-projects to be automatically attached using linked functions
- SSA module function and failure paste operations from libraries now transfer dependent types (e.g. effect types, document groups etc.)
- SSA functions now have 24 text fields attached.
- DAL values (SAE 4754A) are now calculated for functions in the SSA module. DAL values are assigned to each classification. DAL values may now be verified using the fault tree linked to a failure.
- SSA Effects now have a long description field (max 2000 characters)
- PDF files generated from RBD, fault tree and event tree diagrams now have page links allowing users to click on a page reference and move to that page.
- The help system now displays help in the user’s default browser by default. The help files are HTML5 based using a responsive layout that caters for resizing of the parent browser.
