POSSIBILITY OF TECHNICAL SYSTEMS SELFDIAGNOSIS

摘要

The paper addresses in a unitary manner issues regarding the diagnosis of technical products and systems. World- and nationwide the last period of time has been marked by intensive research on aspects related to diagnosis, in most cases taking into consideration concrete practical engineering situations, allowing the establishing of links with fields like artificial intelligence, expert systems, theory of decisions, computer science, theory of measurement, data acquisition technique, thus shaping a systemic approach to diagnosis. Diagnosis has emerged from the necessity of maintaining technical systems in a good operational state, research being driven by the achievement of hardware structures able to rapidly localise and isolate damage (incidents) and replace the affected areas by tolerant configurations, as well as by developing software capable of self-reconfiguration to an operational state at damage/failure parameters, without rendering the system inoperative.
