Support software evolution with abstraction rules and program knowledge patterns. (2002)
Journal Article
Teng, G., & Liu, X. (2002). Support software evolution with abstraction rules and program knowledge patterns. Asian-information-science-life, 1, 177-189

This paper advocates that reengineering is an effective means of legacy system evolution. Extracting formal specification semantically consistent to the original legacy system will facilitate further redesign and forward engineering greatly. The key...

This paper advocates that extracting formal specification semantically consistent to the original legacy system will facilitate further redesign and forward engineering greatly. The three parts of reengineering could be integrated on the basis of a w... Read More about Abstraction: a key notation for reverse engineering in a system re-engineering approach..

Speed and scale up software re-engineering with abstraction patterns and rules. (2000)
Presentation / Conference Contribution
Liu, X., Yang, H., Zedan, H., & Cau, A. (2000). Speed and scale up software re-engineering with abstraction patterns and rules. In International Symposium on Principles of Software Evolution, 2000. Proceedings (90). https://doi.org/10.1109/ISPSE.2000.913

Software reengineering is an essential part of software evolution. Two important issues faced by software reengineering techniques are the time involved and the ability to cope with the scale of software systems. Unless these two issues have been add...

A refinement calculus for the development of real-time systems. (1998)
Presentation / Conference Contribution
Chen, Z., Cau, A., Zedan, H., Liu, X., & Yang, H. (1998). A refinement calculus for the development of real-time systems. In 5th Asia Pacific Software Engineering Conference, APSEC '98 (61). https://doi.org/10.1109/APSEC.1998.733588

We present a calculus which can transfer specifications to objects for the development of real-time systems. The object model is based on a practical OO development technique—HRT-HOOD. A real-time logic is specified by extending a sound formal me... Read More about A refinement calculus for the development of real-time systems..

Improving maintenance through development experiences. (1998)
Presentation / Conference Contribution
Liu, X., Yang, H., & Zedan, H. (1998). Improving maintenance through development experiences. In WESS '98 - Workshop on Empirical Studies in Software Maintenance (1-5)

An empirical comparison is made between present approaches/tools of software maintenance and development. The conclusion is that development technology is more mature in many aspects, such as automation, formalism, confidence, understanding of origin...

Tackling the abstraction problem for reverse engineering in a system re-engineering approach. (1998)
Presentation / Conference Contribution

It is widely accepted that reverse engineering has three components: restructuring, comprehension and production of formal specification. In this paper, we advocate that the three components could be achieved in a systematic approach by successfully...

A design framework for system re-engineering. (1997)
Presentation / Conference Contribution
Liu, X., Chen, Z., Yang, H., Zedan, H., & Chu, W. (1997). A design framework for system re-engineering. In APSEC'97/ICSC'97 - Fourth Asia-Pacific Software Engineering and International Computer Science Conference (342-352). https://doi.org/10.1109/APSEC.

We discuss the current situation of formal methods and their use in the re-engineering of computing systems, especially real time systems. Based on the analysis result, a solution which uses a consistent 4-sector Wide Spectrum Language (WSL) is propo... Read More about A design framework for system re-engineering..

Formal methods for the re-engineering of computing systems. (1997)

This paper presents a short review of formal methods and their use in the re-engineering of computing systems. Five classes of formal notations and theories, namely state/model-based, logic-based, algebraic-based, process algebra and net-based formal...
