Data-Driven Asset & Process Modelling
Model equipment block topologies, simulate plant Availability (Ao), perform Weibull life calculations, and optimize spares stocking strategies natively aligned with ISO 14224 standards.

Intelligent Modelling Engineering
Build mathematical models that describe exactly how your facility behaves, where the bottlenecks lie, and when failures are expected.
Interactive RBD Diagrams
Model equipment configurations in series, parallel, k-out-of-n, or complex nested logic on a graphical canvas, then roll component reliability up into system-level availability (Ao) for the whole production unit.
Censored Weibull Modeling
Fit censored Weibull life distributions the right way — still-running assets are treated as suspensions via median-rank regression with Johnson-adjusted ranks, so failure risk is never overstated. Read $\beta$ to separate infant mortality, random, and wear-out, with confidence bounds on every estimate.
Monte Carlo Simulations
Discrete-event Monte Carlo that samples time-to-failure by inverse-CDF Weibull and repair times via Box-Muller lognormal, iterating until the results converge. Compare preventive maintenance against run-to-failure on cost and availability, with P10, P50, and P90 output bands.
Poisson Spares Optimization
Bridge availability modelling to the storeroom. Compute Poisson spare-parts demand from modelled failure rates and lead times to size stock, hit service-level targets, and prevent stockouts without over-carrying inventory.
Aligned to ISO 14224
IREAMS structures asset records natively on standard O&G taxonomic levels (Enterprise ➔ Site ➔ Unit ➔ System ➔ Equipment ➔ Component). Work orders cannot be closed against systems; they must drill down to Equipment or Maintainable Component levels to keep MTBF and failure-history records clean.
Authoritative Data Dictionary
- ✔️ Locked Taxonomies: Equipment dictionaries lock automatically upon first operational closed transaction.
- ✔️ Management of Change: Structural edits require administrative digital sign-offs to protect history.
- ✔️ Standard Failure Modes: Mapped to OREDA and ISO industry failure definitions.
