中文摘要：

为了提高变型设计结果的有效性,提出对变型设计主模型中的参数进行标定与容差划分的思想。针对参数标定问题,通过构建定制产品相关的质量特性指标及其综合模型,并基于定制产品实例数据得到的关键参数取值区间作为约束条件,运用多目标优化的遗传算法,计算得到使综合指标取值最佳的参数标定值。针对容差划分问题,基于田口式三步设计方法,分析参数变化造成的产品成本损失以及性能偏移,在综合指标允许的范围内,得到参数允许的容差区间。通过参数标定和容差划分,使得基于产品变型设计主模型派生得到的定制产品实例都能满足质量特性指标的需求,从而提高成功派生变型设计实例的比率。最后,通过一个实例对上述原理和方法进行验证。

英文摘要：

In order to improve the validity of variant product,calibration and tolerance identification to the parameters of master variant model is proposed.Aiming at calibration issue,quality characteristic indicators associated with customization product and its synthesis model are constructed,and then the range of key parameters attained from customized product instances is used as constraints.Based on these,parameter calibration value that makes synthesis indicator achieve its optimization is worked out by using multi-objective optimization genetic algorithm.Aiming at tolerance identification,the tolerance range of parameter is calculated within the allowance range of synthesis indicator by analyzing the product cost loss and indicator excursion on the basis of the three stage design of Taguchi method.As a result,a validity variant instance that satisfies the requirement of quality characteristics can be derived from the master product variant model,so the ratio of successfully deriving variant instance is increased.Finally,an example is given to verify the above-menotioned principle and method.
