An Interval-Based Approach to Modelling Time in Event-B

An Interval-Based Approach to Modelling Time in Event-B
Our work was inspired by our modelling and verification of a cardiac pacemaker, which includes concurrent aspects and a set of interdependent and cyclic timing constraints. To model timing constraints in such systems, we present an approach based on the concept of timing interval. We provide a template-based timing constraint modelling scheme that could potentially be applicable to a wide range of modelling scenarios. We give a notation and Event-B semantics for the interval. The Event-B coding of the interval is decoupled from the application logic of the model, therefore a generative design of the approach is possible. We demonstrate our interval approach and its refinement through a small example. The example is verified, model-checked and animated (manually validated) with the ProB animato

Abstract

Our work was inspired by our modelling and verification of a cardiac pacemaker, which includes concurrent aspects and a set of interdependent and cyclic timing constraints. To model timing constraints in such systems, we present an approach based on the concept of timing interval. We provide a template-based timing constraint modelling scheme that could potentially be applicable to a wide range of modelling scenarios. We give a notation and Event-B semantics for the interval. The Event-B coding of the interval is decoupled from the application logic of the model, therefore a generative design of the approach is possible. We demonstrate our interval approach and its refinement through a small example. The example is verified, model-checked and animated (manually validated) with the ProB animato
