产品研制过程动态质量策划

针对动态制造环境下的产品研制过程,为了确保在研制目标、研制状态和研制环境动态变化的情况下实现产品质量目标,提出了以质量活动为单元的产品研制过程动态质量策划模型,在产品研制各个阶段动态识别质量目标,并根据质量目标选择合适的质量措施.分析了产品研制过程中质量特性5个方面的属性,提出基于质量特性的属性对质量目标进行动态识别、对质量措施进行分类的方法.通过将质量目标与质量措施进行动态匹配以合成质量活动,并采用加权0-1目标规划法,充分考虑产品研制目标和各项约束条件,建立优化算法及其数学模型,实现了产品研制各阶段的动态质量策划.通过案例应用验证了所提出理论与方法的正确性与有效性,为产品研制动态质量策划提供了一种系统化的方法.

Dynamic quality planning in product development

In order to facilitate product development under dynamic manufacturing environment, methodologies and technologies were developed to support dynamic quality planning. A dynamic quality planning model (DPQM) for dynamic product development was proposed based on quality activities. The attributes of quality characteristics (QCs) were divided into five aspects for analyzing their evolution during the dynamic product development. The quality objectives were identified through the analysis of the specifications and engineering requirements of QCs at a specific product life cycle stage, followed by classification of quality operations according to their effects on the QCs. A dynamic mapping algorithm between quality objectives and quality operations for configuration of quality activities was presented, together with mathematical model of goal programming for quality planning. The framework for the use of the proposed methodology to solve the problem of measurement quality planning in aerospace manufacturing environment was reported, and the resulting optimization in the dynamic quality planning was discussed.
