摘要
利用遗传灰色系统理论和方法对液氯储罐焊接质量进行评价,在分析灰色GM(1,1)模型建模机理的基础上,利用遗传算法优化此模型,提高评价精度,节约人力和物力。实例表明,遗传灰色系统理论和方法对焊接质量进行评价是可行的,且具有显著的预测精度。
This paper makes use of mostly the genetic - gray system theory and method to evaluate the welding quality, according to the lnodeling mechanism of GM （ 1, 1 ）, the optimum model is given on genetic algorithm. This method enhances the evaluating precision and saves the cost. An example shows genetic - gray system theory and method are useful to evaluate the welding quality, and have a high forecast precision.
