Weaving an Assurance Case from Design: A Model-Based Approach

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Assurance cases are used to demonstrate confidence in properties of interest for a system, e.g. For safety or security. A model-based assurance case seeks to bring the benefits of model-driven engineering, such as automation, transformation and validation, to what is currently a lengthy and informal process. In this paper we develop a model-based assurance approach, based on a weaving model, which allows integration between assurance case, design and process models and meta-models. In our approach, the assurance case itself is treated as a structured model, with the aim that all entities in the assurance case become linked explicitly to the models that represent them. We show how it is possible to exploit the weaving model for automated generation of assurance cases. Building upon these results, we discuss how a seamless model-driven approach to assurance cases can be achieved and examine the utility of increased formality and automation.
