Abstract
The technique of Model Checking has been developed in computer science to algorithmically prove that a formally specified model fulfils a given property, e.g. the exclusion of critical states. While successful applications are known in the semiconductor industry, applications to other fields are promising. This paper considers the use of model checking to support the safe design of process plant control systems. The starting point is a graphical representation of the flow of information between the process and the devices under control. This representation, called Process Control Event Diagram (PCED), can be translated into a modular symbolic model, which describes the behaviour of the system in terms of logical expressions. The translation makes use of library models of devices that are commonly found in process plants. The user will only have to fill in certain specific details. The checking of the symbolic model is carried out using SMV, an existing model checking tool. The approach is illustrated using an industrial cracking reactor.
