    • An expert system for retrieving molding conditions, in which a statistical technique is added to the functions of the conventional expert system, causes of defects are inferred from the records of countermeasures taken and inputted defect occurrence status, conditions for temporary molding are obtained while repeating test molding, qualitative defects are extracted from defects occurred, a boundary of a region in which defects occur is determined with decision analysis of qualitative defects extracted with the use of said record of countermeasures as above, a condition for molding to eliminate said qualitative defects is determined on the basis of the boundary of region of defects occurrence, quantitative defects are extracted from defects occurred, and molding conditions for eliminating said quantitative defects are determined by performing analysis of variance depending on design of experiment with said quantitative defects extracted from said record of countermeasures, whereby the frequency of experiment is greatly reduced in executing statistical technique, countermeasures to a plurality of defects causing mutual actions are taken readily, and reliability of molding conditions to be obtained is increased.
    • 用于检索成型条件的专家系统,其中将统计技术添加到常规专家系统的功能中,从所采取的对策的记录和输入的缺陷发生状态推断缺陷的原因,同时重复测试时获得临时模制的条件 通过使用上述对策记录提取的定性缺陷的判定分析来确定缺陷发生的区域的边界,确定定性缺陷,确定缺陷发生区域的边界,确定消除所述定性缺陷的成型条件 在缺陷发生区域边界的基础上,从发生的缺陷中提取定量缺陷,通过根据实验设计进行方差分析来确定用于消除所述定量缺陷的成型条件,其中从所述对策记录提取的所述定量缺陷 ,f 执行统计技术大大降低了实验的需求,容易引起相互作用的多个缺陷的对策,提高了获得的成型条件的可靠性。
