We report on the use of model checking techniques for both the verification of a process
control program and the derivation of optimal control schedules. Most of this work has been …

We report on the use of the SPIN model checker for both the verification of a process control
program and the derivation of optimal control schedules. This work was carried out as part of …

One of the main obstacle that prevents model checking from being widely used in industrial
control systems is the complexity of building formal models out of PLC programs, especially …

This article reports on the systematic design and validation of a PLC control program for the
batch plant that has been selected as a case study for the EC project on Verification of …

More extensive work on formal methods is now available for checking PLC (Programmable
Logic Controller) programs. Some approaches propose taking into account just the control …

Verification of critical software is a high priority but a challenging task for industrial control
systems. Model checking appears to be an appropriate approach for this purpose. However …

In this paper, we apply formal verification and falsification of temporal logic specifications to
analyze chemical plant automation systems. We present new results, obtained by applying a …

Programmable logic controllers (PLCs) are heavily used in industrial control systems,
because of their high capacity of simultaneous input/output processing capabilities …

The paper analyses two approaches to organize the control requirements in PLC
programming and the PLC response time provided by these approaches. The first one, the …

Most of CERN's industrial installations rely on PLC-based (Programmable Logic Controller)
control systems developed using the UNICOS framework. This framework contains common …
