Robots are becoming ubiquitous: from vacuum cleaners to driverless cars, there is a wide
variety of applications, many with potential safety hazards. The work presented in this paper …

SysML is a variant of UML for systems design. Several formalisations of SysML (and UML)
are available. Our work is distinctive in two ways: a semantics for refinement and for a …

SysML, dedicated to system design, provides graphical models. One of the strengths of
these graphical models is that they can be validated by domain experts. However, the …

The success of automated reasoning presents us with an interesting peculiarity: while
modern solving tools can handle gigantic real-world instances, they often fail miserably on …

Human designed systems are growing in complexity, with increasing numbers of
components and behavior combinations, resulting in more emergent and unintended …

Statechart modelling notations, with so-called 'run to completion'semantics and simulation
tools for validation, are popular with engineers for designing systems. However, they do not …

Verifying learning robotic systems is challenging. Existing techniques and tools for
verification of an artificial neural network (ANN) are concerned with component-level …

Model-based systems engineering (MBSE) is a methodology that entails creating and
utilizing models across the entire system development lifecycle. Based on the Unified …

Complex systems are a collection of sub-systems linked together to represent an integrated
whole. The design of such systems should represent the interactions between their sub …

Abstract Safety-Critical Java (SCJ) is a version of Java for real-time, embedded, safety-
critical applications. It supports certification via abstractions that enforce a particular program …
