基于EPMM的软件过程行为偏离诊断研究

近年来,随着对PSEE认识的深入,人们逐渐发现实际观察到的过程执行往往和实施的过程模型之间存在一定的偏离(deviation),从而导致PSEE对于实际软件开发活动失去了指导意义。针对软件过程偏离问题,以软件演化过程元模型(EPMM)为基础,在软件过程偏离发现方面,借鉴进程代数的弱互模拟思想,提出过程行为空间表达式,用以构造软件过程的行为空间来检测过程偏离;在软件过程偏离处理方面,提出过程偏离类型的划分及偏离处理策略。这种方法能够发现软件过程实施中普遍存在的过程偏离问题并加以处理来改进软件过程,最终提高软件产品质量。

Research on Deviation Diagnostic of Software Process Behavior Based on EPMM Modelling

In recent years,with in-depth understanding of PSEE,people gradually discover that there are certain deviations between the enacting process model and the actual observed process,which leads to the PSEE loses guiding significance for the actual software development activities.For the process deviation problem,based on the software evolution process meta-model (EPMM),on the side of software process deviation detecting,this paper proposed the process behavior space expression on learning process algebra weak bi-simulation ideas in order to detect the process deviation.On the side of software process deviation handling,the process deviation division of type and handling strategy were given.This method can effectively find prevalent deviations problems in the software process implementation, and improve the software process through dealing with the deviation problems,ultimately improve the quality of software products.
