云服务模式下设计方案的优选决策方法

A method of design scheme optimization decision-making based on quality function configuration and rough set theory was proposed aiming at the problem that the diversity and difference of users are not fully considered in the multi-objective optimization decision-making process of design scheme under cloud service mode. The design decision-making process mode and fuzzy evaluation mechanism participated by users were introduced based on the analysis of cloud service mode in order to meet the needs of users cluster analysis and intelligent transformation. The evaluation index system of design scheme for user needs was established to quantify the importance of evaluation index of design scheme in the process of networked collaborative design. The third-order model of design scheme optimization decision under cloud service mode was proposed according to the principle of combining science and system. The model was solved combined with rough set theory and rough approximation ideal solution. The validity and feasibility of the method were verified by taking yacht design scheme on cloud service platform as an example.
