  May 12, 2017

  🚀 Release Notes

  🚀 This release introduces limited and experimental support for event tree analysis.
  Only necessary and sufficient functionalities are implemented
  to allow the most common and basic analysis.
  🚀 Moreover, the release doesn't implement any optimization specific to event-tree analysis.

  Major Changes

  • Event Tree Analysis (#150)
  • Event-Tree-Fault-Tree Linking (#152)
  • Event-Tree Chaining (#151)
  • MEF 'set-house-event' Instruction (#179)
  • ✅ MEF Test-Event Expressions (#68)
  • MEF Numerical Operations (#72)
  • MEF Boolean Operations (#73)
  • MEF Conditional Operations (#67)

  Minor Changes

  📦 Fedora RPM Package

  Report product-order distribution (#168)

  👍 XInclude support

  The Open-PSA MEF compliance:

  • House event state expressions are optional and can be implicitly defined to False.
  • CCF level numbers are optional.
  • CCF factors can be declared in any order.
  • Multiple 'model-data' containers are allowed within a single 'opsa-mef' element.

  - Gate formulas can have literal constant args (true, false) instead of house-events.

  Interval-based expression sample domain validation (instead of min-max)

  🖨 Print line numbers in XML schema validation error messages

  ⚠ Report warning messages with XML attributes in the results-layer instead of XML elements.

  🐛 Bug Fixes

  • Fail to assign a label to a pass-through gate (#166)
  • Zero/One probability events (division by zero total probability) (#169)
  • Segfault with single-event fault tree importance analysis with BDD (#170)

  March 13, 2017

  February 12, 2017

  🚀 Release Notes

  Analysis and post-analysis facilities work directly with a ZBDD-based product container
  without paying memory or speed overhead of converting ZBDD into other data structures.

  Major Changes

  • ZBDD as a fault tree analysis result (product/cut-set) container (#159)
    • Qualitative analysis speedup from 10% to 5x (the more the products, the bigger the effect)
    • Memory consumption decreases by 1.5 - 4x (noticeable only for million or more products)
    • Iteration over products is ~2x slower (graph walk vs. sequential array of products)
    • Quantitative analysis with approximations (rare-event, MCUB) is 2 - 10x slower
      (the fewer the products, the worse the effect)

  Minor Changes

  • 🏁 Package for Windows (#157)
  • 🍎 Package for macOS (#158)
  • 👍 HTTPS support for the website

  🐛 Bug Fixes

  • Incorrect formula for Histogram distribution expected value (#149)
