The
LOGAN Monte Carlo Simulation package is designed to assess process availability.
The system simulates both binary systems (working/not working) and systems
capable of operating at various levels of production. The system has the
following main features:
- Full
Microsoft Windows™ operation (compatible with Microsoft Windows™ 95/98/Me/XP/NT/2000)
- Assessment
of the availability of logic systems (failure/success), production availability
of analogue systems with degraded levels of operation and mixed systems
(e.g. services as logic, production line as analogue)
- Import/Export
logic model from RMC’s LOGAN Fault Tree module
- Choice
of on screen editor: Reliability Block Diagram format or LOGAN success
logic diagram format
- Output
in graphical or tabular formats with statistical analysis of results
- Multi–page
RBDs or logic diagrams
- Facility
to animate the simulation, helping users to better visualise and understand
the process being modelled
- Models:
- effect
of limited spares holdings and spares re-order times
- effect
of limited repair resources
- duty/standby
arrangements
- majority
vote logic
- revealed
failures
- unrevealed
failures and proof testing
- effect
of batch deliveries of raw materials, batch take-offs of product and
limited buffer storage
- time
dependent failure probabilities using Weibull distribution
- MTBF
and MTTR probability distributions including normal, lognormal, rectangular,
fixed, etc.
RMC
recognises that many simulation problems have unique aspects often not covered
by a general-purpose model. The system can therefore easily be modified
to incorporate custom features.
