Defects in safety-critical software systems can cause large economical and other losses.
Often these systems are far too complex to be tested extensively. In this work a formal …

Validation is an important task in complex embedded system designs. A method of
modelling and analysing embedded systems with programmable logic controllers is …

There is an ongoing change in the industry in which old analogue instrumentation and
control (I&C) systems are replaced with new digital ones. New digital systems enable more …

Instrumentation and control (I&C) systems play a crucial role in the operation of nuclear
power plants and other safety critical processes. An important change that will be going on …

Abstract Modern digitalized Instrumentation & Control (I&C) systems set new challenges for
safety evaluation. Model checking is a promising formal method that can be used for …

A method is described for modelling, verification and automatic generation of code for PLC
controllers. The requirements for a controller are modelled using UML state machine …

Control Systems are used to produce a certain result with little or no human supervision. The
principal aim of such systems is to ensure that resources are used efficiently and that the …

The safety of many industrial systems is directly related to time. Model checking has been
used to verify that safety requirements are met by a model of the system. In many cases …

This paper shows how real-time temporal logic can be used for the verification of safety-
critical systems. Heuristics are provided that help the designer to construct a proof diagram …

Timing aspects are important for the correctness of safety-critical systems. It is crucial that
they are carefully analysed in designing such systems. UPPAAL is a tool designed to …
