基于数据处理的航天器总装过程风险管控

针对航天器总装过程的风险识别与控制要求,提出一种基于数据处理的风险评价模型.该模型依托生产管理软件系统,选取设计文件变更次数、工艺文件变更次数和工装不满足工序要求数等为统计原始数据,依据经验公式量化地计算出总装各个阶段的风险,针对不同风险等级采取相应的风险控制措施,并应用到我国航天器总装过程管理中.在某遥感卫星的应用中,该模型在整星总装研制周期压缩25%的条件下,实现了"零缺陷"的质量目标,表明了所述方法在航天器总装过程风险管控中的有效性.

A Risk Management Based on Data Processing During Spacecraft Assembly

According to the risk identification and control requirements for spacecraft assembly process, a risk management model based on data processing has been suggested. The model is based on the data from product management software, and the design change times, the number of process documentation alternation, the number of tooling failure to meet requirements are selected as risk evaluation indexes. According to the empirical formula, all risk quantitative indicators in each period are calculated, and the corresponding risk control measures are took. The risk management model has been applied successfully in China's spacecraft assembly. For the situation in a remote sensing satellite assembly, although the cycle time reduction was compressed by 25%, zero defects have been achieved during the assembly, which indicates the effectiveness of the method in risk control of the spacecraft assembly process.
