Specification and Validation of Behavioural Protocols in the rCOS Modeler [chapter]

Zhenbang Chen, Charles Morisset, Volker Stolz
2010 Lecture Notes in Computer Science  
Components are specified in rCOS, a relational calculus for Refinement of Component and Object Systems.  ...  The rCOS modeler implements the requirements modelling phase of a model driven component-based software engineering process.  ...  Specification of behaviour in rCOS usually considers trace languages of method invocations instead of data.  ...

Robustness testing for software components

Bin Lei, Xuandong Li, Zhiming Liu, Charles Morisset, Volker Stolz
2010 Science of Computer Programming  
First, a set of paths is generated to cover transitions of the state machine, and it is used by the test cases to bring the component into a specific control state.  ...  Robustness testing is a testing methodology to detect the vulnerabilities of a component under unexpected inputs or in a stressful environment.  ...  Acknowledgements We would like to thank the anonymous reviewers of the FACS'08 version and of this version for their detailed comments that helped in revising the paper to its current form.  ...

2008 Lecture Notes in Computer Science  
We demonstrate how rCOS supports modelling different views and their relationships of the system and the separation of concerns in the development.  ...  We give a model of requirements based on an abstraction of the use cases described in Chapter 3.2.  ...  Acknowledgements The authors thank Wang Xu and Siraj Shaikh at UNU-IIST for helpful suggestion on CSP and FDR, and the careful reviewers.  ...

Integrating Theories and Techniques for Program Modelling, Design and Verification [chapter]

Bernard K. Aichernig, He Jifeng, Zhiming Liu, Mike Reed
2008 Lecture Notes in Computer Science  
This submission presents our understanding of the Grand Challenge and propose an agenda on how we will position our research to contribute to this world-wide collaborative research project.  ...  This proposal is made on behalf of all members of the academic staff at UNU-IIST. We would like to thank our colleagues, Chris George, Dang Van Hung and Tomasz Janowski for the discussions.  ...  Therefore, for a component C, we treat the interface methods of C and the protocol as the specification of the use cases of the component and the components in environment of C as the actors of these use  ...

A Component-Based Access Control Monitor [chapter]

Zhiming Liu, Charles Morisset, Volker Stolz
2008 Communications in Computer and Information Science  
We present a formal specification of an access control monitor using the calculus of refinement of component and object systems (rCOS).  ...  A control of access to information is increasingly becoming necessary as the systems managing this information is more and more open and available through non secure networks.  ...  This work was supported by the project HTTS funded by the Macao Science and Technology Development Fund and by the projects NSFC-60673114 and 863 of China 2006AA01Z165.  ...

Harnessing Theories for Tool Support

Zhiming Liu, Vladimir Mencl, Anders P. Ravn, Lu Yang
2006 Second International Symposium on Leveraging Applications of Formal Methods, Verification and Validation (isola 2006)  
The paper concludes with a discussion of feasibility of developing the proposed add-ins and of the conditions for such extensions to be actually used.  ...  In order to know where such add-ins will fit, we investigate the use of an existing successful commercial tool and identify suitable places for adding formally supported checking, transformation and generation  ...  The theory of rCOS shares the idea with Circus [3] in their attempts to combine event-based models and state-based models.  ...

Towards a Rigorous Approach to UML-Based Development

Zhiming Liu, Jifeng He, Xiaoshan Li
2005 Electronical Notes in Theoretical Computer Science  
We discuss the promises and problems of UML-based development.  ...  We then suggest a framework in which UML can be used precisely and more disciplined so as to solve the problems and meet the promises better.  ...  To validate expressions and commands in a dynamic binding environment, the model must keep track of the current type of each object.  ...

Component-Based Modelling for Scalable Smart City Systems Interoperability: A Case Study on Integrating Energy Demand Response Systems

Esther Palomar, Xiaohong Chen, Zhiming Liu, Sabita Maharjan, Jonathan Bowen
2016 Sensors  
The proposed architecture, called refinement of Cyber-Physical Component Systems (rCPCS), which extends the refinement calculus for component and object system (rCOS) modelling method, is implemented using  ...  With rCPCS implementation in Reo, we specify the communication, synchronisation and co-operation amongst the heterogeneous components of the system assuring, by design scalability and the interoperability  ...  Author Contributions: E.P. and S.M. set the problem statement and system model; E.P., Z.L. and J.B. conceived and designed the modelling architecture; E.P., X.C. and Z.L. conceived and designed the implementation  ...

Conformance notions for the coordination of interaction components

Rodrigo Ramos, Augusto Sampaio, Alexandre Mota
2010 Science of Computer Programming  
These notions are formalised in terms of the denotational semantics of the process algebra CSP, and assist the designer in common activities during integration, such as the substitution of component specifications  ...  We illustrate the application of these notions through a systematic composition strategy of software frameworks, and we mechanically verify the preservation of behavioural component properties in these  ...  However, the component communication mechanism model in rCOS is specific for method invocation [36] .  ...

Combining Techniques to Verify Service-based Components

Pascal André, Christian Attiogbé, Jean-Marie Mottu
2017 Proceedings of the 5th International Conference on Model-Driven Engineering and Software Development  
Modelling real life systems covers three aspects of a system (structure, dynamics and functions) and one verification technique is not sufficient to check the properties related to these aspects.  ...  Early verification is essential in model-driven development because late error detection involves a costly correction and approval process.  ...  A component protocol is defined here as the set of all the valid se-quences of service invocations.  ...
