基于有向循环图的多学科设计优化模型调度方法

复杂产品的多学科设计优化过程中，往往会涉及到不同学科的专业分析模型以及各种商业软件应用的集成调度运行问题。在多学科设计优化过程中模型应用集成的基础上，结合设计模型的调度需求，研究了多学科模型的调度运行，并给出了基于有向循环图的通用模型调度解决方案，包括回路探测算法和模型调度算法。最后设计并实现了支持复杂产品多学科设计优化软件框架——iDesign的调度引擎，并以一个设计模型的调度为例，验证了方法的正确性和可行性。

Direct Cycle Graph Based Scheduling Approach of Model in Multidisciplinary Design Optimization (MDO)

The design of complex product usually needs to integrate and schedule multidisciplinary analytic models and applications. Based on the integration77 of models in MDO and the scheduling requirements, the scheduling of MDO models are was researched and a solution based on direct cycle graph method, which includes two important algorithms - cycle detect and model schedule, was put forward. The scheduler of iDesign was implemented, and an example was given to demonstrate the validity and feasibility of the method.
