“…To solve this problem they present reactive Petri nets [15]. Other examples of extended Petri nets applied to workflow modeling is the one presented in [17] where Ha et al use timed colored Petri nets (allowing differentiation among tokens and the inclusion of time restriction) to model dynamic product development processes; or the use of hierarchical Petri nets (HPN), where each place substitutes a lower level Petri net, presented by Boualem in [11] or by Alt et al who use HPN to represent grid workflows [9].…”

Nowadays business process management is becoming a fundamental piece in many industrial processes. To manage the evolution and the interactions of the business actions it is important to accurately model the steps to follow and the resources needed by a process. Workflows provide a way of describing the order of execution and the dependencies between the constituting activities of business processes. Workflow monitoring can help to improve and to avoid delays on industrial environments where concurrent processes are carried out.In this article a new Petri net extension for modeling together workflow activities with their required resources is presented: resource-aware Petri nets. Moreover an intelligent workflow management system for process monitoring and delay prediction is introduced.Resource aware Petri nets include time and resources into the classical Petri net workflow representation, facilitating the task of modeling and monitoring workflows. The workflow management system monitors the execution of workflows and detects possible delays through resource-aware Petri nets.In order to test this new approach, different services from a medical maintenance environment have been modeled and simulated.

Abstract. Workflow interoperability across enterprises boundaries presents a significant challenge recently. Process-view provides a promising way to crossorganizational workflows design. A multi-agent system combined with Petri net based process-view approach is proposed to facilitate cross-organizational workflows management. Within this multi-agent system, a Petri net algebra model and a character string mapping algorithm are proposed to automate the mapping from a Petri net workflow model to a process-view workflow model; the synchronization points are added to integrated process-view workflow models to coordinate the execution of cross-organizational workflow instances.
