摘要:

应用分类和预测技术对机械产品设计数据库进行数据挖掘,针对各种部件影响成本的关键因素建立了基于判定树的产品成本预测模型,并与专家系统相结合,通过数据挖掘来调整专家系统的规则库,从而使专家系统规则不仅可以来自专家经验的总结,而且可以来自对以往产品数据的挖掘,拓宽了知识获取的途径,提高了知识获取的效率.最后给出了一个基于分类和预测技术的产品成本评估系统的框架.

Abstract:

The classification and prediction technology is applied to the mechanical product design database data mining, the product cost prediction model based on the decision tree is established for the key factors affecting the cost of various components, and the rule base of the expert system is adjusted through data mining in combination with the expert system, so that the rules of the expert system can not only come from the summary of expert experience, but also from the mining of previous product data, which broadens the way of knowledge acquisition and improves the efficiency of knowledge acquisition. Finally, a framework of product cost evaluation system based on classification and forecasting technology is given.
