PATTERNS INVOLVING MULTIPLE INSTANCES

MI without synchronization

Runtime independent thread by condition

12，在运行期创建独立实例（线程、程序等）

MI with a priori known design time knowledge

Design time priori Instance

13，设计期多实例，且需全部完成

MI with a priori known runtime knowledge

Runtime multi Instance by condition/free

14，运行期可基于条件创建多实例

MI with no a priori runtime knowledge

Runtime multi Instance free by people

15，运行期可手工随意创建多实例

STATE-BASED PATTERNS 

Deferred Choice

XOR Split(By choice)

16，“推着走”流程，或基于既定条件分支

Interleaved Parallel Routing

OR Split + OR Join, Parallel

17，多分支聚合，分支执行顺序由运行期确定

19，在指定的活动取消

Cancel Case

Cancel Anywhere/Anytime

20，任意时候可取消
