IFAS was developed by a Portuguese research group (CA3) within UNINOVA Research Institute. It is a software implementation of a monitoring and early warning system that can be applied to multiple domains involving multiple sensor data. It is a highly flexible mechanism that can be easily adapted to particular problem and has the capability of dealing with imprecision, allowing the system to issue levels of warnings before an error actually occurs. It extracts data from sensors, and semi-automatically transforms and represents it as linguistic variables - with a flexible reasoning process that can detect different levels of deviations (errors) from nominal behaviours.
