摘要: 针对航天型号产品研制过程的质量成本管控方法展开研究,构建了面向航天型号研制过程的多层次、变粒度、闭环控制的质量成本管控总体模型,该模型将集团-院-厂所3级组织体系与型号研制过程和质量成本管理策略融为一体.针对不同管控层次在控制粒度、过程与内容的不同,分别给出了面向集团、院、厂所的质量成本管控方案.方案将管控过程分成事前、事中和事后3个阶段,并将相应的分析方法、工具、信息融入各阶段,从而构成了各层次质量成本管控闭环.设计开发了支持多级协同的分布式质量成本管理系统——QQ-WebCost,并成功应用于某企业信息化建设项目中.Abstract: The method of quality cost management for the development process of aerospace product was studied. The overall management model of quality cost was proposed, in which the three-layer organizational structure, product development process and the management strategy of quality cost were combined. Furthermore, the method for quality cost management of each layer was presented in which the control granularity, process and object were taken into account. The control process was divided into three stages, control before the event, control during the event and control after the event. The analytic technique, tools and information were integrated, and the closed-loop control policy was applied. Finally, a quality cost management software system based on browser/server architecture was developed, which is called QQ-WebCost, and it has been implemented in an aerospace enterprise.
