中文摘要： 针对设计更改传播的连锁反应问题，提出可变性设计动态响应与更改传播的基本原理，包括多维度的更改关联模型构建、设计更改的本体建模、更改传播的路径演化与动态响应、更改定量分析与评价指标的解耦映射等：依据结构上高聚低耦的强连接与低聚高耦的弱连接关系，构建结构维度更改关联模型；引入生命周期维度的装配序列与制造资源约束，构建进化后的多维度更改关联模型；定义更改基型与组合方式，实现设计更改本体建模，通过约束集合定义与约束满足实现进行传播路径演化；研究更改尺度变化与传播过程（异步并发、环路迭代、增量式反馈）动态响应特性；更改定量分析与评价指标进行解耦映射实现效应评估。在此基础上，建立更改模体结构识别与聚合重用的可变性设计方法：从更改关联模型中识别提取更改模体结构，通过更改模体结构的聚合重用，将模体结构可变性归并进系统可变性，实现系统架构层面的可变性设计。开发原型系统，结合高档数控机床产品进行应用验证。

英文摘要： In order to solve the difficulties in the knock-on effects of change propagation, the principles of change propagation and dynamic response orienting Design for Changeability(DfC) is presented. It includes the construction of the multidimensional changeable relative models, modeling of design change, path evolution and dynamic response of change propagation, and changeable quantitative analysis of decoupling reflection and evaluation. The changeable-relative-model of structure-dimensionality would be constructed based on the relationship between strong-tie of high-clustering low-coupling and weak-tie of low-clustering high-coupling. And the changeable relative model would be constructed after the evolution if it had joined the assembly sequence and productive resources constraints with lifecycle-dimensional factor. Define change basis and combination mode, and achieve the modeling of design change. Change propagation path evolution is accomplished with the difinition of constraint-set and balance resolution of constrain comuting. The changeable relative model is the carrier that research for the character of dynamic response and path evolution progress such as asynchronous concurrent mode and loops causing iteration and incremental feedback of the change propagation. Evolution of the knock-on effect of change wi
