Tecsa S.r.l. is available for the execution of complete RAMS studies including:
- Functional System Block Diagrams (FBD);
- FMECA (“Failure Mode Effects and Criticality Analysis”) / FMEDA / FMEA analysis of components, systems and installations;
- System Reliability Block Diagrams (RBD);
- Register of critical equipment and items (instruments, parameters, etc.);
- List MTTF/MTTR Equipment and Components;
- Equipment and Components Fault Characteristics List;
- Definition of maintenance requirements, maintenance policies, spare parts list, etc.
- Modelling the degradation of a component over time in order to estimate its availability, taking into account operating conditions, external and stress events, emergency conditions;
- Modeling the availability of an industrial plant (manufacturing, process chemical, mining) also for the purpose of measuring the importance and sensitivity of the equipment involved;
- Analysis (also with “business intelligence” and “data mining” tools) of field data for the estimation of failure rates and the evaluation of “proven in use”;
- Optimisation of inspection, test and maintenance intervals;
- Criticality analysis and ranking within a complex system;
- Business interruption risk analysis also in relation to the requirements of a business continuity management system and a business risk management system in accordance with the reference standards (ISO 22313 and ISO 31000 respectively).
In particular, for RAMS analyses, both self-produced calculation codes with specialist platforms (Mathematica, Matlab, Simulink and Mathematica SystemModeler) and specialised commercial calculation codes are used, both in verifying plant availability and in defining the most appropriate maintenance and spare parts management strategy such as RAMP from Reliass. These codes make it possible, given the model of a plant or a process, to quickly verify, often also visually, its behaviour with respect to different use cases and scenarios in such a way as to highlight its limits even in stress conditions determined by limit situations that may be identified through specific methods (e.g. “What-if?” analysis).
