随着市场竞争的日趋激烈,迫切地需要将产品的质量、成本、效益和顾客的满意度等市场竞争要素一起综合考虑进行稳健性设计.采用灰色聚类多指标综合评价对定性、定量指标用灰数的白化权函数加以聚类,对试验方案进行初步筛选,然后在备选方案中对同属于“优”类别的方案进行综合分析,得到一组最佳可控因子组合,并进行验证性分析.最后利用此方法对一款洗衣机用串激电机从成本、效益和顾客满意度方面综合进行考虑,进行了稳健性设计,得到真正意义上的低成本、高质量、高可靠性和高效益的产品,从而最终为解决这种带有模糊性因素的多指标优化问题开创了一种稳健性设计新思路.
With the increasingly fierce market competition, it is urgent to consider the market competition elements such as product quality, cost, efficiency and customer satisfaction together for robust design.Using gray clustering multi-index comprehensive evaluation to qualitative and quantitative indicators Gray number of whitening weight function to be clustered, the initial screening of the test program, and then in the alternative programs belong to “excellent ” category comprehensive analysis to obtain a combination of the best controllable factors, and Confirmatory analysis.At last, we use this method to synthetically consider a series motor for washing machine from the aspects of cost, efficiency and customer satisfaction, carry on the robust design, get the true low cost, high quality, high reliability and Efficient products, and ultimately create a new idea of robust design to solve this multi-index optimization problem with ambiguity.
