摘要: 为了提高基于实例推理方法在枪械方案设计领域的检索精度和设计知识重用程度,提出针对变型设计过程的基于实例推理的设计方案获取和方案修改方法。针对枪械设计过程,建立包括知识库、推理驱动引擎、实例检索模块和规则修改模块的实例推理流程;根据3类不同的指标需求形式设计了对应的相似度计算方法,提高检索精度;通过规则知识的定义和约束实现对设计方案进行定量化、适应性修改,获取最终的方案。开发了基于实例推理的枪械方案快速设计原型系统,并以枪管为例验证了该检索算法的精度,以及所提方法的有效性和实用性。

Abstract: To improve the design knowledge reuse level and retrieval precision of case-based reasoning method in firearm scheme design, a design scheme and a revise method are proposed based on case-based reasoning for variant design process. A case-based reasoning framework is firstly established, including knowledge base, main reasoning engine, case retrieval module and rule-based revise module. For three different design requirements, a corresponding similarity calculation method is then proposed to improve the case retrieval accuracy. Similarity cases obtained in retrieval phase are quantifiably and adaptively revised to get the final design scheme by introducing the concept of rule knowledge. A firearm rapid scheme design prototype system is developed, and a barrel design example is presented to verify the accuracy of retrieval process and the effectiveness and practicality of the proposed method.

Key words: ordnance science and technology, case-based reasoning, variant design, case revisal, scheme design
