A constraint relation dependence graph (CRDG) is applied to express the dependence of coupling constraints, and establish the numerical and symbolic coupling constraints model.
采用约束关系依赖图(CRDG)表达耦合约束之间的依赖关系，从而建立数值与符号耦合约束模型。

This model could capture geometric constraints effectively and distinguish user's intentions automatically in the process of drawing graph theory so as to realize parametric design of apparel pattern.
此模型能有效捕捉并自动识别服装制板过程中反映用户设计意图的几何约束关系，实现服装纸样的参数化。

The result is that the delay-Jitter-SPF algorithm and the flow graph of the building of the multicast tree with QoS constraints are proposed.
