【摘要】 针对纸浆质量分级评价界限具有模糊性的问题,利用投影寻踪、遗传算法、插值型曲线和纸浆质量评价标准,分析样本的最佳投影值及其对应质量等级的关系,构建了评价纸浆质量的投影寻踪插值模型(GPPIM)。实例研究表明,基于投影寻踪插值模型的评价结果与模糊评价结果一致,该方法客观可靠、精度高,是更具应用前景的新方法。更多还原

【Abstract】 In order to solve the fuzziness problem in the evaluation of pulp quality,the methods of projection pursuit,genetic algorithm,interpolation technique and lots of sample data from the evaluation standards of pulp quality were employed,and a novel model——genetic projection pursuit interpolation model(GPPIM),was presented for pulp quality evaluation based on the relationship between the best project value and corresponding quality level.The case studies showed that the evaluation results of GPPIM are consistent with that of fuzz mathematical model.The new method features objective modeling,credibility,effectiveness and promising application.更多还原
