面向产品生命周期的质量数据模型

在对产品生命周期和产品进化链质量保证过程分析的基础上,提出了一种面向产品生命周期和产品进化链的多层次质量数据模型.该模型以融合产品结构模型和产品进化模型的广义物料清单作为单一数据辐射源,通过产品进化模型完整表达产品的改进过程,实现了产品进化生命周期内的质量数据的集成.在产品生命周期内将广义物料清单的多视图按产品生命周期质量管理过程实例化,并以此作为质量数据载体.围绕质量数据载体阶段性的质量管理过程组织产品实现过程中质量业务活动,以质量业务活动为基础,完成具体的质量数据对象的操作与关联,通过"载体-过程-活动-业务对象-物理数据"的关联实现了产品生命周期质量数据的集成.

Quality data model in product lifecycle

A multi-layered quality data model framework was proposed to support product lifecycle based on the analysis of quality data throughout product lifecycle and product evolution process and action chain. The model was comprised of 6 layers, the core of which was the general bill of material(GBOM) layer made up of product structure models and product evolution models. Under the constraint of product structure, GBOM was mapped into several bill of material(BOM) views throughout a product′s lifecycle. According to the process of quality management for product lifecycle, each BOM view was then instantiated as carriers of quality data. At each stage, the quality operation activities that link quality data objects were organized around the carriers, the center of the management process. Mapped successively among carrier layer, quality process layer, quality activity layer, quality object layer and physical data layer, quality data were integrated throughout a product′s lifecycle.
