从描述复杂产品开发的数据特点出发,提出基于“产品-环境”的系统模型,建立支持产品集成开发的数据基础结构。该模型由需求、功能、结构、语境数据信息组成。采用树形数据语境,实现数据的有效组织和管理结构;建立模型的控制语境,完成对任务执行逻辑关系及时序关系的定义。构建系统模型的数据追踪机制,实现对产品开发过程中用户需求、设计任务及目标的追踪。
Based on the characteristics of data describing complex product development, this paper proposes a system model based on “product - environment” and establishes a data infrastructure that supports product integration development. The model consists of demand, function, structure, contextual data information. The tree data context is used to realize the effective organization and management of data structure. The control context of the model is established to complete the logical relationship and the definition of the timing relationship between tasks. Construct the data tracking mechanism of the system model to track the user requirements, design tasks and goals in the product development process.
