摘要: 为满足开发过程产品结构数据的动态结构配置、动态任务协作、动态目标求解、动态状态跟踪等应用需要,在对开发过程产品结构属性及其相互关系进行分析的基础上,提出了一种面向开发过程应用的产品结构形式化模型.结合产品开发活动的时域行为特征,给出了产品结构的时域定义,并以此为基础构建了产品结构模型的时域扩展定义.通过分析产品状态与开发任务时域行为的映射关系,在产品结构时域扩展定义的基础上,提出了基于时间截面的开发过程产品结构状态追踪方案及算法,并通过模拟产品对象在开发过程中的状态变迁过程,验证了模型及相关应用方案的实用性和有效性.

Abstract: Based on the analysis of product structure properties and their relationships throughout product developing process, a formal product structure model was proposed to satisfy application requirements of dynamic structure configuration, dynamic tasks collaboration, dynamic objectives solution and dynamic state tracking. Considering the performance and characteristics of product developing activities in time domain, time domain definition of product structure was presented on the basis of which the product structure model extended in time domain was established. By analyzing the mapping relationship between product state and time domain performance of product developing activities, product state tracing scheme and related arithmetic based on time section were provided, which would play an important part during the process of putting the product structure model into practice. Finally, practicability and validity of the formal product structure model and its related theoretics were demonstrated by simulating a product state tracing instance.
