云服务模式下设计方案的优选决策方法

针对云服务模式下设计方案在多目标优选决策过程中未能充分考虑到用户多元化和差异性的需求问题，提出结合质量功能配置和粗糙集理论的设计方案优选决策方法. 该方法在分析云服务模式的基础上，引入用户参与的设计决策过程方式和模糊评价机制，对用户需求进行聚类分析和智能转化. 建立面向用户需求的设计方案评价指标体系，对网络化协同设计过程中的设计方案评价指标的重要度进行准确量化. 遵循科学性与系统性相结合的原则，提出云服务模式下设计方案优选决策三阶模型. 结合粗糙集理论和粗糙逼近理想解法，对该模型进行求解. 以云服务平台上的游艇设计方案为例，验证该方法的有效性和可行性.

Optimal decision-making method of design scheme in cloud service mode

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.
