基于动态工作流系统的软件过程改进与控制

Workflow simulation for software process improvement

针对软件过程改进存在的问题,提出了基于工作流仿真技术的思路。将工作流仿真贯穿到软件过程改进的整个生命周期。首先,提出了一个支持软件过程改进的动态工作流实施框架,其中包括4个反馈环节来实现改进;建立了指导建模的软件工作流元模型,它将度量和过程改进的几个要素结合到一起,便于仿真评价,并且利用对象约束语言形式化描述模型实体本身和实体间的完整性约束关系。其次,给出了基于ECA规则的工作流模型定义和仿真引擎的结构。第三,在上述基础上针对一个软件开发过程的实例,根据过程度量指标分析了多种可能的改进方案。

Software process improvement（SPI） plays an important role in software engineering research. SPI＇s study can be grouped by different depth and breadth. In dimension of depth,SPI relates to the meth- odology, the technology and the tool. And in dimension of breadth,SPI comprises the process, the prod- uct, the resource, the organization and the metric. The framework for SPI based on workflow was presen- ted. It consists of four feedback cycles for process improvement. A software workflow Meta modal that fa- cilitates to guide modeling was given. It combines metrics and four process improvement elements, de- scribed formally by object constraint language. From the viewpoint of the tool, the workflow modal defini- tion based on ECA rule and the architecture of simulation engine was given. Finally, an example about software development process was provided. Three improvement solutions were analyzed according to the process metrics.
