A gap still exists between the complexity of real discrete-event systems (DESs) and the effectiveness of state-of-the-art diagnosis techniques. To deal with this gap, a novel class of discrete-event systems, called higher-order DESs (HDESs) is introduced, along with a relevant diagnosis technique. The behavior of a HDES is stratified, resulting in a hierarchy of cohabiting sub-DESs, each one living its own life. The communication between subsystems at different levels relies on complex events, occurring when specific patterns of transitions are matched. Diagnosis of HDESs is context-sensitive and scalable.

Abstract
A gap still exists between the complexity of real discrete-event systems (DESs) and the effectiveness of state-of-the-art diagnosis techniques. To deal with this gap, a novel class of discrete-event systems, called higher-order DESs (HDESs) is introduced, along with a relevant diagnosis technique. The behavior of a HDES is stratified, resulting in a hierarchy of cohabiting sub-DESs, each one living its own life. The communication between subsystems at different levels relies on complex events, occurring when specific patterns of transitions are matched. Diagnosis of HDESs is context-sensitive and scalable.File in questo prodotto:
