摘　　要：产品的装配需要人、工具等装配资源的支持,由于生产现场中人员流动、设备维护等因素,使得装配资源具有一定的不确定性,零/部件装配序列需要随之进行调整以避免因装配等待而造成的效率降低。针对这一问题,本文提出将装配资源作为一种动态约束,定义了装配资源状态信息矩阵。以此为基础构造了装配资源影响因子并将之引入了目标函数中,讨论了基于遗传算法进行装配序列动态规划的具体操作和流程。最后,结合CATIA二次开发,以某型飞机壁板的装配为例对方法进行了验证。The assembly of products needs the supporting of assembly resources such as operators and tools, and because of some factors such as staff mobility and equipment maintenance, there is some uncertainty on assembly resource, so the assembly sequence need adjust-ment to avoid efficiency reducing caused by waiting. To solve this problem, this paper proposes an idea to treat as-sembly resources as one kind of dynamic constraint, and define an assembly resource status information matrix. The impact factor of assembly resource is added in the construction of the objective function, and the genetic al-gorithm is adopted to execute the real-time planning of as-sembly sequence. Finally, with the secondary development of CATIA, the assembly of a simple panel of some aircraft is used as an example to validate the correctness of this method.
