| Abstract | |
This document is derived from a research that involves the proposal of a service-oriented architecture for a system that integrates and coordinates a set of teleoperated production systems. This system is physically located in a dispersed way and adopts a modeling approach based on a formal tool known as Petri net. This approach structures a procedure to model construction to develop functional analysis of the parts integrating the system and that subsequently are implemented in distributed control architecture. The text presents the motivations for the research regarding the history of development of productive systems (PSs), a review of the literature where, among other aspects, it is shown the approaches of other researchers to ensure the structural flexibility of the PSs; the proposal for an architecture based on a formulation of a service-oriented approach, a proposal for modeling procedure, and an implementation example of these proposals. The development of this work contributes to the area of PSs enabling them to ensure a structural flexibility that facilitates the reconfiguration of the system against changes in the productive environment. In this sense, considering the heterogeneity of PSs, this work proposes a modular approach with service-oriented principles, where two important features are conciliated: high degree of autonomy and global interoperability of the modules. Additionally, the developed proposal ensures a precise specification of the messages exchange among the modules of the PSs. (AU) | |
