S.ESCAF: Sequential Complex Systems are Analysed with ESCAF through an Add-on Option

This article presents the new possibilities afforded by S.ESCAF for analysis of sequential systems with very complex Markov diagrams. S.ESCAF is an add-on option to the commercially available desktop ESCAF unit. The user builds an electronic simulation of the studied system in a very simple manner based directly on the system diagram. A sequential events combination generator (SCG) then inputs all allowable time sequences of events to this electronic simulation¿component failures, repairs, non-starts, etc. S.ESCAF analyzes the resulting output state to determine those sequences which result in system failure. Its originality lies in its ability to generate and analyze all events sequences, taking into account the order of occurrence of the events, even for complex systems. Maximum capacity is 80 events.
