Assert, Negate and Refinement in UML-2 Interactions

چکیده

The Unified Modeling Language (UML) is the industry standard for modeling. With its recent advancement to version 2.0, there have been large amounts of changes and additions. In this paper I study some new features with a view to formal specification and verification, in particular the operators neg and assert, and notions of refinement based upon them.

Trace Semantics of Interactions in UML 2.0

The Unified Modeling Language (UML, see [27]) is the industry standard for modeling software intensive systems. Recently, the standard has been upgraded from version 1.5 to 2.0, introducing significant changes and additions. In particular, Message Sequence Charts (MSC) according to the ISO standard (see [13, 12]) have been integrated. In UML, the concept underlying these notations is called int...

STAIRS - Understanding and Developing Specifications Expressed as UML Interaction Diagrams

STAIRS is a method for the step-wise, compositional development of interactions in the setting of UML 2.x. UML 2.x interactions, such as sequence diagrams and interaction overview diagrams, are seen as intuitive ways of describing communication between different parts of a system, and between a system and its users. STAIRS addresses the challenges of harmonizing intuition and formal reasoning b...

STAIRS - Steps to Analyze Interactions with Refinement Semantics

The paper presents STAIRS, an approach to the compositional development of UML interactions supporting the specification of mandatory as well as potential behavior. STAIRS has been designed to facilitate the use of interactions for requirement capture as well as test specification. STAIRS assigns a precise interpretation to the various steps in incremental system development based on an approac...

On the Definition of UML Refinement Patterns

In this article we describe an approach towards increasing the robustness of the UML refinement machinery. The aim of this work is not to formalize the UML notation itself, but to substantiate a number of intuitions about the nature of possible refinement relations in UML, and even to discover particular refinement structures that designers do not perceive as refinements in UML.

Language and Tool Support for Class and State Machine Refinement in UML-B

UML-B is a ’UML-like’ graphical front end for Event-B that provides support for object-oriented modelling concepts. In particular, UML-B supports class diagrams and state machines, concepts that are not explicitly supported in plain Event-B. In Event-B, refinement is used to relate system models at different abstraction levels. The same abstraction-refinement concepts can also be applied in UML...
