Basic Features... A valuable reliability software package (like Relex) incorporates: Accuracy Speed Flexibility Ease of use Integration Automation

Relex Accuracy Relex calculations are accurate: Conform to chosen standard Calculations are either done by exact formulas or using Monte Carlo simulation Calculation results are traceable by user

Relex Speed Relex offers high speed calculations: Use of libraries increases data input Import of component data minimizes workload Use of default data for parameters which are currently not available All modules use same data base (no data exchange necessary)

Relex Ease of Use Relex can be used very easily: Windows based screen-layout and functions All modules use same interface Copy / paste features for data Drag-and-drop features for report generation Graphic tool and import/export wizard like in Microsoft Excel®

Relex Flexibility Relex offers many flexible options: Customizable input formats (screen tables) Flexible Report Design options Custom Parts Libraries, Default Files, Derating Files, Input Forms, etc. Ability to move between analyses with one click Ability to import data in many formats

Relex Automation Relex offers many automated features: Calculate failure rates based on defaults Component failure modes entered RBD figures linked to System Tree components Advanced automated importing/exporting Fault Trees generated from a FMEA

Relex Integration All Relex products are fully integrated: Data is entered into one program. Repetitive data entry eliminated. Data between the products is shared.
