Such concurrent systems as Web services and workflow systems can be viewed as a composition of a set of subsystems. Subsystems interact with each other through a set of message channels in order to perform a task. This work defines a class of Petri nets called interactive Petri nets (IPNs) to model these systems. IPNs can be used to analyze their behavior, find potential problems, and then improve...
In many complex electromechanical systems, fault propagation between nodes always leads system-level BIT false alarms. Therefore, this paper aims at reducing system-level BIT false alarms based on the research of small-world properties of fault propagation in large-scale systems. Firstly, find out community centers in the system which has small-world network properties, and then divide the system...
