针对卫星设计意图分解过程中存在重视分解结果,轻视分解过程的现象,提出基于元意图链的典型设计意图树提取方法。首先,在定义相关概念的基础上,通过逆向推理和均值法得到设计意图的典型元意图链;然后,通过Apriori算法提取出典型元意图组合并将其融合成典型设计意图树;最后,通过实例验证说明了该方法的有效性。 Aiming at the phenomenon that the disassembly result is emphasized in the process of satellite design intent decomposition and the decomposition process is neglected, a typical design intention tree extraction method based on meta-intention chain is proposed. First of all, based on the definition of related concepts, the typical meta-schematic intent chain of design intention is obtained by inverse reasoning and mean value method. Then, the typical meta-schematic intension groups are extracted by Apriori algorithm and merged into a typical design intention tree. Finally, Verification shows the effectiveness of this method.
