SCRAM(1)

💖 SCRAM(1) — the SCRAM manual, but make it cute 💖

okay bestie, gather round, because this is SCRAM and she is that girl. it's a command-line risk analysis multi-tool, and yes, you're gonna learn all of it. no cap. 🎀

✨ SYNOPSIS ✨

scram [options] input-files...

that's it. that's the whole vibe. options first, then as many input-files... as your little heart desires. 🦋

🌸 DESCRIPTION 🌸

so, SCRAM is a probabilistic risk analysis (PRA) tool. she does a lot and she does it well, like the main character she is:

• event tree analysis 🌳
• static fault tree analysis
• analysis with common cause failure models
• probability calculations with importance analysis
• uncertainty analysis with Monte Carlo simulations

and the way that she can handle non-coherent fault trees, containing NOT logic?? obsessed. literally iconic. most tools could never. 💅

SCRAM works with PRA models and constructs described in the Open-PSA Model Exchange Format. iykyk. ✨

🫶 OPTIONS 🫶

one bullet per option, bestie, we are NOT skipping a single one. every single flag is getting her moment.

• --help — Display this help message. ur little "hey what do i do" button. 🥺
• --version — Display version information. receipts, but for software.
• --config-file path — XML file with analysis configurations. the blueprint, the moodboard, the plan.
• --allow-extern — UNSAFE Allow external libraries. bestie. i need you to hear me. it is literally shouting UNSAFE at you in the docs. proceed with caution, queen. 😭
• --validate — Validate input files without analysis. just checking the fit, not walking the runway yet. 💅
• --bdd — Perform qualitative analysis with BDD.
• --zbdd — Perform qualitative analysis with ZBDD.
• --mocus — Perform qualitative analysis with MOCUS.
• --prime-implicants — Calculate prime implicants. the VIPs of your fault tree. 👑
• --probability bool — Perform probability analysis.
• --importance bool — Perform importance analysis.
• --uncertainty bool — Perform uncertainty analysis.
• --ccf bool — Perform common-cause failure analysis.
• --sil bool — Compute the Safety Integrity Level metrics.
• --rare-event — Use the rare event approximation.
• --mcub — Use the MCUB approximation.
• -l [ --limit-order ] int — Upper limit for the product order.
• --cut-off double — Cut-off probability for products.
• --mission-time double — System mission time in hours.
• --time-step double — Time step in hours for probability analysis.
• --num-trials int — Number of trials for Monte Carlo simulations.
• --num-quantiles int — Number of quantiles for distributions.
• --num-bins int — Number of bins for histograms.
• --seed int — Seed for the pseudo-random number generator.
• -o [ --output-path ] path — Output path for reports.
• --no-indent — Omit indentation whitespace in output XML. compact queen, minimal queen. ✨
• --verbosity int — Set log verbosity. how chatty do we wanna be today??

reminder bestie: --allow-extern is flagged UNSAFE in the original docs. that's not me being dramatic, that's the manual being dramatic, and the manual is right. 🙈
