Reliability and Maintainability

RAMS analysis

  • Assessment of the reliability and availability of process plant and complex technological systems using conventional methods (FMECA, FTA, etc.), and innovative techniques (Markov chains, Integrated Dynamic Decision Analysis and Fuzzy Logic);
  • Maintenance planning optimisation (Reliability Centred Maintenance – RCM);
  • Assessment of the Safety Integrity Level: for process plants (ISO 61511), machines (ISO 62061) and automotive (ISO 26262);
  • Development of Reliability Databanks based on company-specific information (e.g manintenance data) or on data from commercial databanks (ESReDA, OREDA, AIChE et al.);

Integrated Dynamic Decision Analysis (IDDA)

  • Logical-probabilistic modelling of complex systems. Development of a “dynamic” event tree, representing all the sequences of events compatible with the description received from the perspective of both the “logical” construction and the “probabilistic” coherence;
  • Phenomenological modelling of systems, to be integrated with the logical -probabilistic model to represent the physical behaviour of the system in case of deviations;
  • Decision-making support. Starting from the model of the analyzed system, an analytical representation of the possible alternatives and of the risk (in terms of probability and consequence) is obtained.
