Logan Monte Carlo Simulation

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 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 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.

We 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.
