Advanced Reasoning Tool for Model-Based Diagnosis of Industrial Systems

Objective

Industry is characterised by increasing complex technological processes and sophisticated equipment that must be supplemented by advanced automation systems to ensure efficient, safe and cost-effective production. In this context, it is crucial to guarantee high plant availability by minimising down-time. The aim of ARTIST is to match this need of strategic importance by developing tools allowing to diagnose from observation of the system variables the causes of a failure and, possibly, to early detect developing faults.
Industry is characterised by increasing complex technological processes and sophisticated equipment that must be supplemented by advanced automation systems to ensure efficient, safe and cost effective production. In this context, it is crucial to guarantee high plant availability by minimizing down time. This need of strategic importance has been met by the development of tools allowing the diagnosis from observation of the system variables, the causes of a failure and, possibly, developing faults.

The system is based on a new approach to diagnosis, model based reasoning. this allows reasoning to be based on first principles, using a qualitative and/or quantitative model of the domain.

It has been developed with a view to first application in 2 widely different, economically important industrial processes: electricity transmission and oil refining. In these areas 2 complementary demonstrations were set up: one seeking to identify the operating conditions of the major devices of the electricity transmission network: the other the operation of a crude oil refinery. The technology developed in the project can be applied in many industrial areas, such as power generation, chemical processes and diagnosis of electronic circuitry.
ARTIST is based on a new approach to diagnosis, model-based reasoning, now regarded as an evolutionary path from expert systems. Whereas expert systems rely on representing the knowledge human experts in order to solve the problems, model-based reasoning allows reasoning to be based on "first principles", using a qualitative and/or quantitative model of the domain.
