针对客户定制产品设计灵活性差的问题，提出一种基于遗传算法的产品基因重组的设计方法。在产品的重组 设计中引入基因工程，利用遗传算法对现有的产品设计方案进行优化，以满足制造业客户定制产品的多样化需求，实现客户定 制产品的智能设计。以某机械制造企业的数控机床为例，完成了遗传算法的关键技术：适应度函数、选择算子、交叉算子的设 计开发，验证了该方法的可行性和有效性。

Aiming at the problem of poor design flexibility of customized product, a genetic algorithm based on genetic algorithm is proposed. The recombinant gene engineering is introduced in product design. The existing product design schemes are optimized by genetic algorithm, to meet with the diverse needs of customized products and realize the intelligent design. Taking the numerical control machine of a mechanical manufacturing enterprise as an example, the key technologies of genetic algorithm which are the fitness function, selection operator and crossover operator are designed, verifying the feasibility and effectiveness of the method.
