An approach to integrating semi-formal and formal notations in software specification

Sergiu Dascalu, Peter Hitchcock
2002 Proceedings of the 2002 ACM symposium on Applied computing - SAC '02  
As such, the correspondence between the diagnmunatic (scurd-formal) and textual (formal) parts of a specification is typically limited to a subset of the speeification's components.  ...  modeling approach and combine the advantages of graphical, semi-formal notations with those of formal notations is RoZeLink [28] .  ...  using Statecharts and FNLOG) or semi-formal~semi-formal (e.g., [29] , where an integration UM]JLean Cuisine+ is proposed for supporting the early stages of interactive system design).  ...

Formal Aspects of Enterprise Modeling Methods: A Comparison Framework

Domenik Bork, Hans-Georg Fill
2014 2014 47th Hawaii International Conference on System Sciences  
Thereby, the formalization of modeling methods is essential to unambiguously define their structure, behavior, and semantics, and enable an intersubjective understanding and machine-processability.  ...  In this paper we analyze and compare six common enterprise modeling methods in regard to the formalization of their process-related aspects.  ...  The static notation of function, event, and connector is semi-formally defined by a legend illustrating sample shapes (i.e., a rounded rectangle for functions, a hexagon for events, and edges and arrows  ...

Building Formal Requirements Models for Reliable Software [chapter]

Axel van Lamsweerde
2001 Lecture Notes in Computer Science  
We review various techniques available to date for system modeling, from semi-formal to formal, and discuss their relative strengths and weaknesses when applied during the RE stage of the software lifecycle  ...  , and the assignment of responsibilities for the resulting requirements to agents such as humans, devices, and software.  ...  Semi-Formal Approaches The principle here is to formally declare conceptual units and their links; the properties of such units and links are generally asserted informally.  ...

Frameworks Based on Templates for Rigorous Model-driven Development

Nuno Amálio, Fiona Polack, Susan Stepney
2007 Electronical Notes in Theoretical Computer Science  
This paper advocates an approach to building engineering environments (or frameworks) for rigorous model-driven development (MDD) that is based on combining semi-formal notations with formal modelling  ...  On the one hand, semi-formal modelling approaches that are used in practical, large-scale system development, such as the UML, are not amenable to formal analysis and consistency checking.  ...  All funding and supervision is gratefully acknowledged.  ...

Model Analysis of Equivalence Classes in UML Events Relations

Nazir Ahmad Zafar
2013 Journal of Software Engineering and Applications  
Hence, linking UML with formal approaches will enhance modeling power of software systems.  ...  In this paper, an approach is developed by integrating UML and Z notation focusing on equivalence relation of the state diagrams.  ...  This is because UML structures are based on graphical notations and have informal or semi-formal definitions which are prone to causing errors [4] as mentioned above.  ...

A Formal Model of Peer-to-Peer Digital Product Marketplace

Sylvanus A. Ehikioya
2018 International Journal of Networked and Distributed Computing (IJNDC)  
This paper uses both semi-formal and formal specification methods to model a P2P digital product marketplace.  ...  By using both semi-formal and formal methods in the design of the P2P system, we can reason about and create a correct and reliable system quickly and efficiently. application class.  ...  We use both semi-formal notation such as the UML and formal notation such as the Object-Z for our specification and design.  ...

State Based Static and Dynamic Formal Analysis of UML State Diagrams

Fahad Alhumaidan
2012 Journal of Software Engineering and Applications  
Formal methods are proved powerful, particularly, at requirement specification and design level. For a moment, formal methods are not welcomed because of much use of mathematics in formal languages.  ...  Therefore, a linkage between UML and formal methods is required to overcome the above deficiencies.  ...  In addition to above following benefits are observed: 1) An approach is developed by linking UML to Z notation by defining a relationship among fundamentals of these semi-formal and formal techniques;  ...

Isabelle/SACM: Computer-Assisted Assurance Cases with Integrated Formal Methods [chapter]

Yakoub Nemouchi, Simon Foster, Mario Gleirscher, Tim Kelly
2019 Lecture Notes in Computer Science  
Consequently, assurance techniques should support both formal and informal artifacts, with explicated inferential links between them.  ...  The framework guarantees well-formedness, consistency, and traceability of ACs, and allows a tight integration of formal and informal evidence of various provenance.  ...  This work is supported by EPSRC projects CyPhyAssure 8 , grant reference EP/S001190/1, and RoboCalc, grant reference EP/M025756/1.  ...

2008 Semantic Web Applications and Perspectives  
This methodology produces an integrated enterprise model model that, not only contains a structural (formal) description, but it also includes more informal and semi-formal information.  ...  Nowadays, knowledge engineering provides sophisticated methodologies and tools to support enterprise modelling and production of formal enterprise models.  ...  meta-model) contains informal, semi-formal, and formal information about key aspects of an enterprise.  ...

Closing the Gap between Enterprise Models and Service-oriented Architectures [chapter]

Martin Juhrisch, Werner Esswein
2008 Advances in Computer and Information Sciences and Engineering  
The possibility of a direct link between business workflows and the supporting application system is often seen as the critical strength of the SOA paradigm.  ...  For that kind of configuration the gap between analysis and design phase has to be bridged.  ...  Thus, we need semi-formal languages to model problems, which are not well-structured, highly subjective, and finally not objectively well formed [HR00] .  ...

1999 Lecture Notes in Computer Science  
In our approach, we use the conceptual framework of ODP and discuss some methodological issues related to ODP-viewpoint modelling of distributed systems using UML notations.  ...  We conclude with recognising the power of combining UML and ODP so as to manage the complexity of the problem.  ...  Different semi-formal and formal languages are used for specifying different ODP viewpoints.  ...
