模型驱动的卫星产品变更范围提取技术

产品变更范围的确定是进行变更分析与管理的前提和基础。以卫星型号研制为对象，提出了一种基于模型驱动的卫星产品变更范围提取方法。构建了产品变更冲突模型，实现了对产品变更的规范化、形式化描述；分析了产品变更冲突的几种类型，并探讨了引起变更冲突的原因；提出了相应的产品变更范围提取算法，进而确定全生命周期中不同阶段的产品变更范围，为后续的变更方案的生成和评估奠定基础。以某一卫星型号研制为例，验证了方法的可行性和有效性。

Research on product change range extraction of satellite based on model-driven

Determination of product change range is the basis of the change analysis and management. Taking the aerospace satellite as example, a method of product change range extraction of satellite based on model-driven is proposed. The product change conflict model is constructed, and the product change can be described in standardization and formalization. Several types of product change conflicts are analyzed and the reasons causing change conflicts are discussed. An algorithm of product change range extraction is proposed, and the product change range can be determined in different stages in lifecycle, which is the basis of the subsequent modification scheme generation and evaluation. Taking some a satellite as example, the feasibility and effectiveness of this method is verified.
