An Approach to Modelling Software Evolution Processes

An Approach to Modelling Software Evolution Processes describes formal software processes that effectively support software evolution. The importance and popularity of software evolution increase as more and more successful software systems become legacy systems. For one thing, software evolution has become an important characteristic in the software life cycle; for another, software processes play an important role in increasing efficiency and quality of software evolution. Therefore, the software evolution process, the inter-discipline of software process and software evolution, becomes a key area in software engineering. The book is intended for software engineers and researchers in computer science. Prof. Tong Li earned his Ph.D. in Software Engineering at De Montfort University, U.K.; he has published five monographs and over one hundred papers.

In this chapter, according to the requirements of software evolution and based on
EPMM, an object-oriented software evolution process description language
EPDL is designed. EPDL extends the descriptive power of EPMM. All of the static
components in EPMM are defined in EPDL and the dynamic components in
EPMM are embodied when EPDL programs are executed. An EPDL program can
be regarded as a detailed and extended description of a software evolution
