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

14. 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

15. 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)

16. 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®

17. 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

18. 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

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