Research On CMMI Software Measurement Environment Based On PSM And Tool Implementation

CMMI is the template provided by the Software Engineering Institution of Carnegie Mellon University which is applied to management, improvement and evaluation on software process.The aim of CMMI is the improvement on software process, to control the software development and manage quality effectively.Recently, how to build a Process-Center Software Engineering Environment (PSEE) based on CMMI becomes a research hotspot. The technology of software process measurement plays a more important role in PCEE.Frist of all, this dissertation analyzes the implement process of software process measurement and the core position of the Standard software process in this process, and concludes the elements of the Standard software process. After that, this dissertation provides a software measurement model PSM4CMMI based on CMMI, which uses the PSM theory; This model can resolve the problem that appears in the using model. In addition, under the model, this dissertation provides a software define method SP-TPetri based on time Petri Net's-TPetri, which can be used to describe the complex software process firmly.Finally, on the ground above-mentioned we design and implement the Software Process Measurement and Appraisement System. This system can help the software institution manage its develop process and realize the process improvement.
