Towards Verification of UML Class Models using Formal Specification Methods: A Review

Abstract In today s world many elements of our lives are being affected by software and for that we are in greater need of high-quality software The Unified Modeling Language UML is considered the de facto standard for object-oriented software model development UML class diagram plays an important role in the design and specification of software systems A class diagram provides a static description of system component

Software System Model Correctness using Graph Theory: A Review

The Unified Modeling Language UML is the de facto standard for object-oriented software model development The UML class diagram plays an essential role in design and specification of software systems The purpose of a class diagram is to display classes with their attributes and methods hierarchy generalization class relationships and associations general aggregation and composition between classes in one mode

A Graph Transformation Approach for Modeling and Verification of UML 2.0 Sequence Diagrams

Unified Modeling Language (UML) 2.0 Sequence Diagrams (UML 2.0 SD) are used to describe interactions in software systems. These diagrams must be verified in the early stages of software development process to guarantee the production of a reliable system. However, UML 2.0 SD lack formal semantics as all UML specifications, which makes their verification difficult, especially if we are modeling a critical system where the automation of verification is necessary. Communicating Sequential Processes (CSP) is a formal specification language that is suited for analysis and has many automatic verification tools. Thus, UML and CSP have complementary aspects, which are modeling and analysis. Recently, a formalization of UML 2.0 SD using CSP has been proposed in the literature; however, no automation of that formalization exists. In this paper, we propose an approach on the basis of the above formalization and a visual modeling tool to model and automatically transform UML 2.0 SD to CSP ones; thus, the existing CSP model checker can verify them. This approach aims to use UML 2.0 SD for modeling and CSP and its tools for verification. This approach is based on graph transformation, which uses AToM3 tool and proposes a metamodel of UML 2.0 SD and a graph grammar to perform the mapping of the latter into CSP. Failures-Divergence Refinement (FDR) is the model checking tool used to verify the behavioral properties of the source model transformation such as deadlock, livelock and determinism. The proposed approach and tool are illustrated through a case study

gCSP: A Graphical Tool for Designing CSP systems

For broad acceptance of an engineering paradigm, a graphical notation and a supporting design tool seem necessary. This paper discusses certain issues of developing a design environment for building systems based on CSP. Some of the issues discussed depend specifically on the underlying theory of CSP, while a number of them are common for any graphical notation and supporting tools, such as provisions for complexity management and design overview

International conference on software engineering and knowledge engineering: Session chair

The Thirtieth International Conference on Software Engineering and Knowledge Engineering (SEKE 2018) will be held at the Hotel Pullman, San Francisco Bay, USA, from July 1 to July 3, 2018. SEKE2018 will also be dedicated in memory of Professor Lofti Zadeh, a great scholar, pioneer and leader in fuzzy sets theory and soft computing. The conference aims at bringing together experts in software engineering and knowledge engineering to discuss on relevant results in either software engineering or knowledge engineering or both. Special emphasis will be put on the transference of methods between both domains. The theme this year is soft computing in software engineering & knowledge engineering. Submission of papers and demos are both welcome

An UML+Z Framework For Validating And Verifying the Static Aspect of Safety Critical System

AbstractThe aim of this paper is to propose an augmented framework for verifying and validating the static aspect of safety critical systems by analysing the UML class diagrams and the relationship between them. Since UML is a semi formal language which is provn to ambiguities due to its various graphical notations, hence Formal analysis of UML class diagram is required. Moreover, class diagram play an important role in system designing phase especially in safety critical systems. Any ambiguity or inconsistency in design can result in potential failure. Formal methods are the mathematical tools and methodology which are sandwiched at various stages of software development process to ensure the correctness, consistency and completeness of software artifacts such as requirement specifications, design etc. In this article, Z notation is used for the purpose of analysis formally and later on verified by the Z/EVES tool

Generating Meta-Model-Based Freehand Editors

Most visual languages as of today (e.g., UML) are specified using a model in a meta-model-based approach. Editors for such languages have supported structured editing as the only editing mode so far. Free-hand editing that leaves the user more freedom during editing was not supported by any editor or editor framework since parsing has not yet been considered for meta-model-based specifications. This paper describes the diagram editor generator framework DiaMeta that makes use of meta-model-based language specifications and supports free-hand as well as structured editing. For analyzing freely drawn diagrams, DiaMeta parses a graph representation of the diagram by solving a constraint satisfaction problem
