The notions of modes and mode changes are widely used by the industrial engineers to structure reasoning about different conditions of system functioning. Even though there has been some work on developing modal systems, we still lack a general understanding of how to architect, verify and ensure dependability of such systems. In our work we rely on formal modelling and verification to study intricate relationships between fault tolerance, operation modes and architectural design. date: 2010-04 date_type: published event_title: Eighth European Dependable Computing Conference (Fast Abstract Track) event_location: Valencia, Spain event_dates: April 28-30, 2010 event_type: conference refereed: TRUE citation: Laibinis, Linas and Troubitsyna, Elena and Iliasov, Alexei and Romanovsky, Alexander (2010) System Architecture, Dependability and Modes.
