Reliability Analysis – RELCODE (Developer: QUT)
RELCODE is a research-grade software toolkit from QUT designed for rigorous reliability engineering and life data analysis. It helps engineers, researchers, and quality professionals model component and system reliability, quantify uncertainty, and generate reproducible, publication-ready results. RELCODE brings together modern statistical methods, clear visualizations, and a streamlined workflow suitable for both industrial projects and academic studies.
Key capabilities:
- Life data analysis with support for complete, censored (right, left, interval), and truncated datasets
- Distribution fitting for common life models (Weibull, lognormal, exponential, Gamma, and others)
- Parameter estimation using maximum likelihood and Bayesian methods, with confidence and credible intervals
- Model selection via information criteria (e.g., AIC, BIC) and goodness-of-fit diagnostics, including probability and hazard plots
- Repairable systems and event data modeling (e.g., NHPP, renewal processes) for maintenance and field-return analysis
- System reliability modeling for series, parallel, and k-out-of-n structures, with reliability block diagram support
- Accelerated life testing analysis and stress–strength evaluation for design validation and qualification
- Degradation and trend analysis to infer time-to-failure from condition monitoring data
- Monte Carlo simulation for uncertainty quantification, sensitivity analysis, and reliability prediction
- Reliability growth analysis to track improvements across design iterations and test phases
- Automated reporting with traceable calculations, audit-ready summaries, and publication-quality graphics
- Flexible data import/export (CSV, spreadsheet formats) and a scriptable interface for batch runs and integration into existing workflows
Typical uses:
- Predicting time-to-failure, MTTF/MTBF, reliability, and availability under varying conditions
- Comparing designs, suppliers, or operating regimes using statistically sound methods
- Planning tests and optimizing maintenance based on risk and cost considerations
- Teaching and research in reliability engineering, statistics, and asset management
With transparent algorithms and a focus on reproducibility, RELCODE enables confident decision-making across the product lifecycle—from early design and testing to deployment and sustainment.
