摘要: 从特性关联入手分析并讨论更改传播,提出产品设计中特性关联单元的类型划分,论述特性关联单元的更改传播特征,进而归纳出更改传播的方式、更改传播展开过程以及特性在传播过程中的行为特性.所提出的工程更改传播过程模型为产品设计工程更改方案优化和传播风险评估提供了模型基础.通过气缸设计更改实例对提出的理论进行了初步验证.

Abstract: The propagation of change from characteristic linkage perspective was analyzed. The characteristic relations were categorized into two types, and their propagation features were discussed. Two modes of change propagation were elicited and the process model of change propagation was proposed. The model provides a basis for the optimization of change solutions and evaluation of propagation risk. A case study coming from an example of cylinder design was provided to validate the propagating mechanism.
