Multiobjective planning for flexible product platform based on conjoint analysis and quantitative indices

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.
