“…In this context, several works have provided ways to specify what a correct reconfiguration means. In the work of Mazzara and Bhattacharyya [22], several frameworks for describing and analyzing dynamic reconfiguration are studied, but they do not handle logics similar to Dyn-BLTL. Basso et al [3] express architectural properties in CTL with additional predicates encoding the state of the architecture, but this logic does not allow interleaving quantifiers (over sets) and temporal operators.…”

Abstract. Dynamic software architectures emerge when addressing important features of contemporary systems, which often operate in dynamic environments subjected to change. Such systems are designed to be reconfigured over time while maintaining important properties, e.g., availability, correctness, etc. Verifying that reconfiguration operations make the system to meet the desired properties remains a major challenge. First, the verification process itself becomes often difficult when using exhaustive formal methods (such as model checking) due to the potentially infinite state space. Second, it is necessary to express the properties to be verified using some notation able to cope with the dynamic nature of these systems. Aiming at tackling these issues, we introduce DynBLTL, a new logic tailored to express both structural and behavioral properties in dynamic software architectures. Furthermore, we propose using statistical model checking (SMC) to support an efficient analysis of these properties by evaluating the probability of meeting them through a number of simulations. In this paper, we describe the main features of DynBLTL and how it was implemented as a plug-in for PLASMA, a statistical model checker.

Information system change is concerned with deliberate modifications to an organization's technical and organizational subsystems that deal with information. Changes result in adjustments being made to the configuration of information systems that could have an impact on the operations of those systems. This paper examines the problem of interference between old configuration activities, new configuration activities and reconfiguration activities that occur due to overlapping modes. The paper proposes a novel form of depicting and solving the problem based on a flow-based conceptualization in which a configuration can be viewed as a system of flow systems organized architecturally, described by their internal flows, and connected by external flows and triggering. This method of diagramming is applied to a complex case study involving the reconfiguration of an office workflow for order processing described in BPMN. The diagrams resulting from this method and the BPMN diagrams are then examined side by side. Accordingly, the conclusion is that a new high-level representation seems more systematic as a foundation for building a conceptual schema of business processes.

“…In order to support dynamic, evolving topologies at the modelling level, it is necessary to be able to express dynamic reconfiguration in the modelling language [73,76]. However, for many CPSs, the topology is likely to evolve dynamically, for example, in models of smart transportation, further increasing the complexity of the modelling task.…”
