Service-oriented Computing (SOC) is being applied in industrial manufacturing automation to face the current demand for modular, flexible and reconfigurable solutions. Highlighted from the other existing methodologies, SOC may carry an alternative but natural solution to design and engineer manufacturing automation systems and consequently the ability to seamless integrate into the modern IT-enterprise...
In service-oriented systems, composition of services is required to build new, distributed and more complex services, based on the logic behavior of individual ones. This paper discusses the formal composition of Petri nets models used for the process description and control in service-oriented automation systems. The proposed approach considers two forms for the composition of services, notably the...
This paper introduces a novel method for the specification and selection of criteria-weighted operation modes for the orchestration of services in industrial automation using Petri nets. The objective is to provide to the internal decision support system of a service-oriented automation device or of another applicable computational system the capability to select the best path in a Petri net orchestration...
