Abstract:

In life cycle design， high-dimensional and multi-objective design conflicts are difficult to effectively quantify and resolve. To address this， a life cycle design conflict quantification and systematic resolution method based on a multi-level FSMP model was proposed. First， an FSMP information model was constructed to achieve integrated representation of life cycle design information. Second， design conflicts were decomposed into objective conflicts and decision conflicts： objective conflicts were quantified using the analytic hierarchy process （AHP） and fuzzy comprehensive evaluation （FCE）； decision conflicts were resolved based on the element-name-value model and similarity measure. Then， a breadth-first search algorithm integrated with a pruning strategy was proposed to efficiently search for design solutions with minimized objective conflicts within the constraint resolution domain. Finally， the effectiveness of the method was verified through a case study on conflict resolution in wind turbine system design. The results demonstrate that the proposed method can achieve the quantification and resolution of both objective and decision conflicts.

摘要：

在全生命周期设计中，高维度、多目标的设计冲突难以有效量化与消解，为此，提出了一种基于功能-结构-材料-工艺（FSMP）多层级模型的全生命周期设计冲突量化与消解方法。首先构建FSMP信息模型，实现跨生命周期设计信息的集成表达；然后将设计冲突分解为目标冲突和决策冲突，目标冲突采用层次分析法和模糊综合评价进行量化，决策冲突基于元素-参数-量值模型与相似性度量进行求解；最后提出融合剪枝策略的广度优先搜索算法，在约束消解域内高效搜索目标冲突最小设计方案。风力发电机组的设计案例冲突消解验证了方法的有效性。结果表明，该方法能够实现目标冲突与决策冲突的量化和消解。
