基于实例推理的注射模成本估算系统

模具成本估算是模具制造行业广泛关注的问题，对企业产品的快速报价具有十分重要的意义。本文探讨了利用基于实例的推理（Case-Based Reasoning简称CBR）来估算注射模的成本，对CBR方法的关键技术如：实例的表示、实例的检索、实例的改写及实例的学习进行了着重研究。最后通过一个实例验证了此方法的有效性。

Application of CBR in Injection Mold Intelligent Cost Estimation

Cost estimation for mold is a widely concerned problem in die ＆ mold manufacture industry, which has very important meanings for quotes of company products. CBR （Case-Based Reasoning） was used for evaluating the cost of injection mold in this paper. As four key technologies of the CBR method, case indexing, case retrieval, case adaptation and case learning were focused. Finally, an example was applied to verify the validity of the method.
