The number of applications that process data in a stream basis has increased significantly over recent years due to the proliferation of sensors. Additionally, in cyber-physical systems, physical and software components are deeply intertwined, adding the ability to act on the environment.
In many cases, cloud resources are used for the processing, exploiting their flexibility, but these sensor streaming applications often need to support operational and control actions that have real-time and low-latency requirements that go beyond the cost effective and flexible solutions supported by cloud platforms. The development of these applications cannot be delegated to the magical properties of frameworks and services that promise simple solutions, hiding the inherent underlying complexity of cloud resources. It raises the difficulty of developing complex streaming processing in the cloud and highlights the need for a suitable developing methodology. Moreover, during the developing lifecycle, a number of facets have to be considered such as the design of functional parallel solutions, the impact of a target cloud platform that exhibits different degrees of performance variability, or the need for more complex performance requirement support. This talk will present our experiences in developing Petri Net models for performance sensitive cloud applications thus leveraging the use of formal models in complex scenarios.
We introduce a family of modeling techniques consisting of Petri nets together with a set of rules. For reconfigurable Petri nets, e.g. in  not only the follower marking can be computed but also the structure can be changed by rule application to obtain a new net. Motivation is the observation that in increasingly many application areas the underlying system has to be dynamic in a structural sense. Complex coordination and structural adaptation at run-time (e.g. mobile ad-hoc networks, dynamic hardware reconfiguration, communication spaces, ubiquitous computing) are main features that need to be modelled adequately. The distinction between the net behaviour and the dynamic change of its net structure is the characteristic feature that makes reconfigurable Petri nets so suitable for modeling systems with dynamic structures.
For rule-based modification of Petri nets we use the framework of net transformations that is inspired by graph transformation systems . The basic idea behind net transformation is the stepwise modification of Petri nets by given rules. The rules present a rewriting of nets where the left-hand side is replaced by the right-hand side. The abstract semantics we introduce in  is a graph with nodes that consist of isomorphism classes of the net structure and an isomorphism class of the current marking. Arcs between these nodes represent computation steps being either a transition firing or a direct transformation. Based on this semantics we can define properties and model-check these properties.
Model checking is a widely used technique to prove properties such as liveness, deadlock or safety for a given model. Here we present model checking of reconfigurable Petri nets [7,6]. The main task is to flatten the two levels of dynamic behavior that reconfigurable nets provide, the firing of transitions on the one hand and the transformation of the nets on the other hand. We show how to translate a reconfigurable net into Maude modules . Maude's LTL model-checker is then used to verify properties of these modules. The correctness of this conversion is proven as the corresponding labelled transitions systems are bisimular.
In an ongoing example reconfigurable Petri nets are used to model and to verify partial dynamic reconfiguration of field programmable gate arrays using the tool ReconNet ( or see https://reconnetblog.wordpress.com).
For the successful realization of complex systems of interacting and reactive software and hardware components the use of a precise language at different stages of the development process is of crucial importance. Petri nets are becoming increasingly popular in this area, as they provide a uniform language supporting the tasks of modeling, validation, and verification. Their popularity is due to the fact that Petri nets capture fundamental aspects of causality, concurrency and choice in a natural and mathematically precise way without compromising readability.
The workshop PNSE'17 (Petri nets and Software Engineering) will take place as a satellite event of Petri Nets 2017 and ACSD 2017.
The use of Petri nets (P/T-nets, colored Petri nets and extensions) in the formal process of software engineering, covering modeling, validation, and verification, will be presented as well as their application and tools supporting the disciplines mentioned above.
