摘　　要：本文的研究从深度上涉及方法学、技术和工具层面,从广度上涉及过程、产品、资源、组织和度量。工作流仿真可以贯穿于软件过程改进的整个生命周期。针对技术层面,提出一个支持软件过程改进的工作流实施框架,其中包括四个反馈环节来实现改进。进一步提出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。针对工具层面,给出了基于ECA规则的工作流模型定义和仿真引擎的结构。在此基础上就一个软件开发过程的实例,依据过程度量指标分析了各种可能的改进方案。Software process improvement (SPI) has played an important role in software engineering research. The study on SPI can be grouped by different depth and breadth. In dimension of depth SPI relates to the methodology, the technology and the tool. And in dimension of breadth SPI comprises the process, the product, the resource, the organization and the metric. The workflow simulation can run through the total lifecycle of SPI. From the viewpoint of the technology, an implementation framework for SPI based on workflow is presented. It consists of four feedback cycles for process improvement. A software workflow Meta modal that facilitates to guide modeling is given. It combines metrics and four process improvement elements, which is prepared for evaluating simulation results. Moreover, modal entities and integrated constraint relationships are described formally by object constraint language. From the viewpoint of the tool, the workflow modal definition based on ECA rule and the architecture of simulation engine is given. Finally, an example about software development process is provided. Three improvement solutions are analyzed according to the process metrics.
