They are organized in topical sections on testing and verification, simulation and model checking, SOFL tools, and formal specification and application.

Formal engineering methods are intended to o?er e?ective means for integ- tion of formal methods and practical software development technologies in the context of software engineering. Their purpose is to provide e?ective, rigorous, and systematic techniques for signi?cant improvement of software productivity, quality, and tool supportability. In comparison with formal methods, a distinct feature of formal engineering methods is that they emphasize the importance of the balance between the qualities of simplicity, visualization, and preciseness for practicality. To achieve this goal, formal engineering methods must be - veloped on the basis of both formal methods and existing software technologies in software engineering, and they must serve the improvement of the softwa- engineering process. ICFEM 2008 marks the tenth anniversary of the ?rst ICFEM conference, which was held in Hiroshima in 1997. It aims to bring together researchers and practitioners who are interested in the development and application of formal engineering methods to present their latest work and discuss future research directions. The conference o?ers a great opportunity for researchers in both formal methods and software engineering to exchange their ideas, experience, expectation and to ?nd out whether and how their research results can help advance the state of the art.

In any serious engineering discipline, it would be unthinkable to construct a large system without having a precise notion of what is to be built and without verifying how the system is expected to function. Software engineering is no different in this respect.

Formal methods involve the use of mathematical notation and calculus in software development; such methods are difficult to apply to large-scale systems with practical constraints (e.g., limited developer skills, time and budget restrictions, changing requirements). Here Liu claims that formal engineering methods may bridge this gap. He advocates the incorporation of mathematical notation into the software engineering process, thus substantially improving the rigor, comprehensibility and effectiveness of the methods commonly used in industry.

This book provides an introduction to the SOFL (Structured Object-Oriented Formal Language) method that was designed and industry-tested by the author. Written in a style suitable for lecture courses or for use by professionals, there are numerous exercises and a significant real-world case study, so the readers are provided with all the knowledge and examples needed to successfully apply the method in their own projects.
