SCRAM v0.11.6 Release Notes

Release Date: 2017-02-12 // about 7 years ago

  • 🚀 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)
    • Histogram distribution XML schema missing lower-boundary expression (#148)
