针对汽车产品平台稳健性问题,依据产品开发流程,应用质量功能展开理论,建立了空间变量指数模型,提出了减少顾客需求不确定性的方法。运用案例研究方法,以上海某汽车企业参与全球产品平台开发为例,采用空间变量指数模型进行分析,对模型进行了检验并提出了对策,验证了空间变量指数模型在降低不确定性方面是可行的,最终能够降低成本并实现提升企业竞争力的目标。 According to the robustness of automotive product platform, based on the product development process and applying the theory of quality function, a spatial variable index model was established and a method to reduce the uncertainty of customer demand was proposed. Using the case study method, taking an automobile enterprise in Shanghai involved in the development of a global product platform as an example, this paper uses the spatial variability index model to analyze and test the model and puts forward some countermeasures. It is verified that the spatial variability index model is feasible in reducing the uncertainty , And ultimately reduce costs and achieve the goal of enhancing the competitiveness of enterprises.
