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 model considering different criteria to evaluate the quality of services, such as the
time, energy efficiency and reliability. The transition-invariants obtained from the Petri net represent the set of possible modi
operandi and these are then weighted with decision criteria. The result will be afterwards evaluated in order to select the optimal modus operandi to be executed by the device. Based on the experiments, this method permits the dynamic optimization of processes in real-time, considering available parameters from devices and other resources.
