摘要

针对单一模块化或参数化平台设计中客户需求响应能力不足的问题,提出基于联合分析和定量指数的柔性产品平台多目标规划方法。分析了柔性平台调节特征和优化趋势,建立了柔性产品平台的设计过程模型;引入联合分析获得产品属性重要度和属性水平对客户满意度的效用值,采用质量功能配置获得产品属性和内部组件的关联矩阵;进而提出定量的平台通用性指数和多样化指数,构建柔性平台调节设计的两目标优化模型,并使用多目标进化算法进行求解。总体上实现了柔性平台调节方案的定量分析建模和多目标优化设计。通过液压支架平台调节方案规划实例,证明了所提出方法的有效性。%Aiming at the low responding capability for customer requirements in single modular or parametric platform design,a multiobjective planning method for flexible product platform based on conjoint analysis and quantitative indices was proposed.By analyzing on platform＇s leveraging characteristics and optimization trends,a design process model for flexible product platform was constructed.Through introduction of conjoint analysis,the importance degree of product attributes and utilities of attribute levels for customer satisfaction were achieved.Quality function deployment was applied to acquire the association matrix between product attributes and internal components.The quantitative platform generality index and product diversity index were proposed to construct a two-objective optimization model for flexible platform,which was solved by multi-objective evolutionary algorithms.The quantitative analysis modeling and multiobjective optimization for the flexible platform design were realized.Effectiveness of the proposed method was illustrated by the leveraging planning for large-scale hydraulic support platform.
