摘　　要：大型复杂产品方案设计结构配置过程具有复杂性、多层次、多属性和创造性的特点,对设计知识的合理组织和重用是提高产品设计效率的有效保障。在多级设计分解的基础上,研究了大型复杂产品方案设计多级实例推理与重用技术,提出了多级实例推理关联传导过程的形式化表达模型,建立了多级推理过程的传导效应函数,给出了多级实例推理算法和基于多级实例推理初始方案的实现过程。通过实例验证了所提模型与算法的有效性和可操作性。Due to the complicated,multi-level,multi-attribute and creative process of product structure configuration of complex product scheme design,reasonable organization and reuse of design knowledge were guaranteed for improving product design efficiency.Based on multi-level case decomposition,multi-level case-based reasoning and reuse of scheme design knowledge were studied,a formal expression model of hierarchical association and conductivity reasoning for complex product scheme design was presented,conductivity effect function of multi-level reasoning process was established.And then,multi-level case-based reasoning algorithm was put forward and implementation process of initial design scheme was provided.Finally,an example was used to verify the effectiveness and feasibility of the model and algorithm.
