考虑质量屋模型中顾客需求与产品工程特性之间相关关系具有“少数据”、“贫信息”特点，将灰关联分析引入到质量屋模型中求解产品工程特性重要度。为了在产品设计过程中考虑产品开发成本、技术实现困难、产品市场竞争需求以及实际情况中产品开发成本约束存在的模糊性对产品最优设计的影响，构建一种模糊混合整数规划模型，实现产品工程特性最优设计水平。通过一个智能手机产品改进的案列来验证所构建模型的有效性和实用性。

Considering that the relationship between customer needs （ CNs） and product engineering char-acteristics （ ECs） in House of Quality （ HoQ） model has the characteristics of “small data” and“poor in-formation”, the grey relational analysis is introduced to calculate the importance degree of ECs .Taking in-to account the impact of product development cost , technical realizing difficulties , market competition re-quirements and the actual fuzziness of product development cost restraint on the optimum product design during the process of product design , a fuzzy hybrid integer programming model is established to realize the optimum design level for ECs .Finally, an application to improve the ECs of the intelligent cellphones il-lustrates the effectiveness and practicality of proposed model .
