Summary form only given. The panel moderated by Bernhard Steffen (University of Dortmund) reviews this development, discusses the perspectives, and establishes recommendations for future directions of software engineering, and, in particular, for the future role of formal methods in this area.
In this paper we present a method and tool to fully automatically infer data-sensitive behavioral models of black-box systems in two coordinated steps: (1) syntactical analysis of the interface descriptions, here give...

Large-scale systems increasingly consist of a mixture of co-dependent software and hardware. The differing nature of software and hardware means that they are often modeled separately and with different approaches. Comodeling is a design strategy that allows hardware/software integration issues to be identified, investigated and resolved in the early stages of development. Previous work described a comodeling approach that integrates Behavior Engineering with Modelica. This paper revisits this approach and introduces a new means of integration that natively executes Behavior Trees in Modelica rather than utilizing external functions. This enhanced integration has several benefits. Firstly, it makes comodeling easier to apply as the comodel is captured solely in Modelica. Secondly, it makes the ability to execute Behavior Trees widely available. Finally, it opens the possibility to use comodeling with other complementary approaches such as the virtual verification of system designs against system requirements.
The paper presents a problem statement for a robust stochastic regulator synthesis based on the principles of control on manifolds, a solution algorithm of a new information system and its structure maintaining the sy...

In the past decade, active automata learning, an originally merely theoretical enterprise, got attention as a method for dealing with black-box or third party systems. Applications ranged from the support of formal ve...

We present an active learning algorithm for inferring extended finite state machines (EFSM)s, combining data flow and control behavior. Key to our learning technique is a novel learning model based on so-called tree q...

Graceful degradation is an established concept to improve the resilience of systems, especially when other resilience mechanisms have failed. Its implementation is often heavily tied to the application code and, thus,...
