含有混合变量的协同优化方法研究

Method Study of Collaborative Optimization with Mixed Variables

复杂产品是由多个子系统构成,并且是相互耦合而成的。为解决含有混合变量的复杂产品的协同优化建模问题,根据复杂产品的相互耦合特性,应用协同优化方法,在复杂产品的连续性模型的基础上加入变量分析,建立系统与各个子系统的目标函数与约束函数,得到含有混合变量的复杂产品的协同优化模型,包括了概念模型、总体优化模型、学科优化模型、学科分析模型、变量分析模型、系统集成模型。在文章最后,通过一个工程算例来验证模型的有效性。

Complex products are composed by many subsystems through complex coupling.Due to the mutual coupling of different systems of complex products,the models of collaborative optimization of complex products were built by using the method of collaborative optimization.In order to solve the problems of collaborative optimization modeling with mixed variables,the analysis of variables was combined with the models of collaborative optimization based on continuous variables,additionally,and the object functions and constraint functions were designed,then,mixed-variable collaborative optimization modeling process of complex product was provided,including conception model,system-level optimization model,subsystem-level optimization model,subsystem analysis model,variable analysis optimization,system integration model.The validation of the model was tested by an engineering case.
