产品开发过程中的数据流建模与分析

Data Flow Modeling and Verification in Product Development Process

通过分析产品开发过程管理中各种数据的特征,指出数据流建模和分析在面向产品开发过程的工作流管理系统中格外重要.基于提出的工作流模型,开发了一种面向版本控制的数据流模型,它支持包含任意环的过程结构.引入变量影响列表描述这种数据流模型并给出该模型正确性分析的方法.能够适应面向产品开发过程的工作流管理系统中数据管理的需求.

This paper discusses perspectives of data in product development process management, such as data type, data storage mechanism, and data structure. It is shown that data flow modeling and verification is especially important in workflow management system for product development process. Based on the proposed workflow model with arbitrary cycles, this paper proposes a version control based data flow model which meets the need of product development. To describe the data flow intuitionally and efficiently, the authors introduce variable influence table, and develop an algorism for verifying this data flow model. Earlier practices indicate that the approach meets the data management requirements in workflow management system for product development process.
