Recently, there has been growing interest in formalizing UML, thereby enabling rigorous analysis of its many graphical diagrams. Two obstacles currently limit the adoption and use of UML formalizations in practice. First is the need to verify the consistency of artifacts under formalization. Second is the need to validate formalization approaches against domain-specific requirements. Techniques from the emerging field of requirements traceability hold promise for addressing these obstacles. This paper contributes a technique called retrieval by construction (RBC), which establishes traceability links between a UML model and a target model intended to denote its semantics under formalization. RBC provides an approach for structuring and representing the complex one-to-many links that are common between UML and target models under formalization. RBC also uses the notion of value identity in a novel way that enables the specification of the link-retrieval criteria using generative procedures. These procedures are a natural means for specifying UML formalizations. We have validated the RBC technique in a tool framework called UBanyan, written in C++. We applied the tool to three case studies, one of which was obtained from the industry. We have also assessed our results using the two well-known traceability metrics: precision and recall. Preliminary investigations suggest that RBC can be a useful traceability technique for validating and verifying UML formalizations.

This chapter explores how precise formal methods can be used effectively and practically in interaction design. The term ‘formal methods’ in computer science refers to a suite of techniques drawing on mathematical notions of sets, logic, and functions or precise diagrammatic notations, most of which are currently primarily focused on safety-critical applications in the aerospace or nuclear industries. While research into broader use of these methods could be regarded as a theoretical interest, the early development of formal methods was driven as much by practical considerations as theory. This chapter features two case studies on formal notations and their use in areas of practical interaction design beyond safety-critical applications, as well as understood, used, and appropriated by clients and designers who have no formal training or expertise. Each offers specific notations and techniques to the reader and also explores more general lessons for creating practical formal methods for HCI.

Methods And Techniques

This chapter introduces the main notions related to the dependability of applications in a self-contained way in order to bring the topic near to non-experts, the modeling aspects including requirement formulation in UML, the evolving UML profiles, design patterns for the best practice and basic means for testing and formal methods based validation and verification of designs. We also introduce a method that relies on the introduced standards and model transformation techniques that allows the QoS-driven optimization of enterprise systems architecture. The methods and techniques are illustrated with practical example models and problems.
