We present a new framework for business process management based in a Petri net extension called ResourceAware Petri Nets. This extension considers resources representation at the application level and allows the monitoring of the whole system with its dependencies. Thus, to solve resource usage conflict, agents are proposed to take care of monitoring workflow instances. This new comprehension of dependencies also allows the creation of a delay prediction system based in historical data from the workflows itself. In this paper we expose our methodology for modeling workflows through our extension which is based in classical approaches. Also a monitoring and delay prediction workflow is introduced and analyzed. In order to test our approach, we have extracted workflows from real cases and tested our framework simulating different kind of situations and resources, getting promising results since our prototype can provide early detection of workflows delays.
