Ocl also used to express the consistency constraint 具有一定的應用價值。
The consistency constraints provide a way to decouple the disciplines and make the parallel subsystem optimization possible 通過引進一致性約束條件,實現學科之間的解耦和并行優化。
Then , consistency constraints can by specified and validated using the language and the tools of the semantic domain 方法不但簡單、直觀,而且不需要增加額外的信息,并且可以利用現有的語法分析工具。
In this approach , design tasks are decomposed into a system - level optimization and subsystem - level optimizations . the task of each subsystem optimization is to find the local variables to minimize or maximize objectives , subject to its local design constraints . the task of the system - level optimization is to find global ( or shared ) and auxiliary variables to optimize the system performances , and satisfy the consistency constraints 這種方法將優化流程分為系統級優化和單學科優化兩個層次:系統級優化的任務是通過調整共享設計變量和輔助設計變量,在滿足一致性約束條件下,使系統目標最優;子系統的任務是調整局部設計變量,在滿足本學科的設計要求條件下,使子系統的目標最優。
