Scaling Language Features for Program Verification

Georg Stefan Schmid

Formal verification of real-world software systems remains challenging for a number of reasons, including lack of automation, friction in specifying properties, and limited support for the diverse programming paradigms used in industry. In this thesis we m ...

Code Generation Approach Supporting Complex System Modeling based on Graph Pattern Matching

Jinzhi Lu, Yan Yan

Code generation is an effective way to drive the complex system development in model-based systems engineering. Currently, different code generators are developed for different modeling languages to deal with the development of systems with multi-domain. T ...

Direct Model-checking of SysML Models

Alessandro Tempia Calvino

Model-checking intends to verify whether a property is satisfied by a model, or not. Model-checking of high-level models, e.g. SysML models, usually first requires a model transformation to a low level formal specification. The present papers proposes a ne ...

Applying model checking to industrial-sized PLC programs

Jean-Charles Tournier, Simon Bliudze, Borja Fernandez Adiego

Programmable Logic Controllers (PLCs) are embedded computers widely used in industrial control systems. Ensuring that a PLC software complies with its specification is a challenging task. Formal verification has become a recommended practice to ensure the ...

On Deductive Program Repair in Leon

Viktor Kuncak, Etienne Kneuss

We present an approach to program repair and its application to programs with recursive functions over unbounded data types. Our approach formulates program repair in the framework of deductive synthesis that uses existing program structure as a hint to gu ...

Reactive Programming Abstractions for Complex Event Logic and Dynamic Data Dependencies

Ingo Maier

A large part of software written today is reactive. In contrast to batch mode systems, a reactive program continuously adapts itself to new input which often requires a substantial amount of engineering. Traditionally, reactive programs are implemented in ...

Value Map: A Diagnostic Framework to Improve Value Creation and Capture in Service Systems

Alain Wegmann, Arash Golnam

In this paper, we introduce a problem structuring method (PSM) called “Value Map”. Value Map is an extension to the Supplier Adopter Relationship Diagram in the Systemic Enterprise Architecture Method (SEAM). Value Map assists in understanding, analysis an ...

Programming with Specifications

Philippe Paul Henri Suter

This thesis explores the use of specifications for the construction of correct programs. We go beyond their standard use as run-time assertions, and present algorithms, techniques and implementations for the tasks of 1) program verification, 2) declarative ...

Verification of Imperative Programs in Scala

Régis William Blanc

Safety-critical software systems can only support a limited number of failures. Extensive testing is good at catching errors, however that will never certify their absence. Formal verification is an alternative to testing that can (automatically) provide a ...
