Event-driven service oriented framework for integrative serviceability management of networked manufacturing systems

Abstract

Manufacturingcompanies face frequently changing market demands, time-to-market pressure, continuously emerging new technologies and global competition. To quick respond to ever-changing environment, the intra-enterprise integration of key technology applications is one of the fundamental requirements of the management and supervisory control systems at plant level. This paper presents an event-driven service oriented framework within which main services provided by manufacturing systems at different levels can be effectively managed in a holistic manner. The framework is derived from the analysis of fundamental requirements of three key services of manufacture systems, namely DRAM (dynamic resource allocation and management), RCAR (realtime control and auto-recovery), PMDP (performance monitoring, diagnosis and prognosis). The conceptual designs of the main components of the framework are presented, which include information data model, event triggering and message exchange mechanism as well as Shop-floor Service Bus that enables service oriented architecture.

Synchronization of Linearly Coupled Networks With Delays via Aperiodically Intermittent Pinning Control

“…At first, let us recall the definition of defined in (17), and use the lemma in [41], one can get: is diagonally stable, i.e., there exists a positive definite diagonal matrix…”

“…Compared with the continuous control strategy, discontinuous control strategies have attracted interests gradually from various fields and they can be applied on manufacturing [17], secure communication [18], and so on. Discontinuous control strategies are more economic and can simulate the real world better, including impulsive control [19], sample-data control [20], [21], node-to-node pinning control [22], fast-switching strategy [23], edge snapping pinning control [24], [25], and the event-triggered scheduling algorithm [26], [27].…”

Exponential synchronization of inertial neural network with mixed delays via intermittent pinning control

“…Pinning control is an effective way to reduce the number of controlled nodes in which controllers are only applied to a small fraction of all neural network nodes. In comparison with continuous control, discontinuous control strategies such as intermittent control and impulsive control have been investigated in the field on manufacturing, 38 secure communication, 39 and so on. For example, the signal in signal transmission can be weak because of diffusion, a control strategy which has lower control cost needs to be added, discontinuous control is a good choice.…”
