应用层次分析法计算分插机构优化目标的权重

分插机构优化是一个多目标、多参数优化问题。该文在分插机构可视化辅助分析优化平台上得到多组可行优化结果之后,为进一步评价出最优解,对评判方法中权值的求解方法进行了应用分析。将分插机构的12个优化目标中的10个作为评判方法的评价指标,分别应用层次分析法中的0～2三标度法和1～9标度法确定各评价指标的权值,即通过建立初始评判矩阵和比较矩阵,并通过一致性检验得到最终判断矩阵,继而得到所有目标的权重集,其结果分别为(0.6216,0.2450,0.0881,0.0302,0.0101,0.0033,0.0011,0.0004,0.0001,0.0001)和(0.6892,0.2233,0.0620,0.0175,0.0052,0.0017,0.0006,0.0003,0.0001,0.0001)。2组结果均与实际相符,1～9标度法结果精度更高。试验结果表明,应用AHP求解分插机构的优化目标权值是合理、客观、有效的。此方法可为一般农机多目标优化问题的权值求解起到一定的借鉴作用。
