针对机械产品概念设计中的优化问题，提出了基于多色集合与模糊遗传算法相结合的方案推理及优化方法。首先运用多色集合理论，建立了描述复杂结构机械产品各组成元素间的层次结构和复杂约束关系的信息模型，以进行有效的方案推理。然后，将多色集合推理模型与模糊遗传算法相结合，实现了方案的评价及优化方案的搜索。以工业机械手的概念设计为例对该方法进行了验证，结果表明，该方法能有效地实现概念设计过程中的方案推理及优化，为复杂机械产品概念设计提供了一定的理论基础。

Aiming at solving the optimization problems in the conceptual design of mechanical products, proposal reasoning and optimization approach are proposed based on the combination of polychromatic sets and fuzzy genetic algorithm. To describe the hierarchy and complicated constraints relationship among differ-ent components of complex structure mechanical products, the polychromatic sets theory is applied to carry out the proposal reasoning effectively. The proposal evaluation and the searching of optimization approaches are achieved based on the combination of polychromatic sets theory reasoning model and fuzzy genetic algo-rithm. An instance of industry manipulator is illustrated to verify the effectiveness of the proposed methods. The results show that the proposed methods can achieve the effective proposal reasoning and optimization during the process of conceptual design, which lays some foundation for conceptual design of complex me-chanical products.
