The design process of laminated composites faces two challenges: the engineer designs the product and its morphology, but also, simultaneously, the material. The number of design solutions can be huge since the solution space is very large. Standard CAE systems (CAD, Finite Element Simulation) do not offer to the designer an approach to explore these solution spaces efficiently and interactively. This paper provides a possible procedure for engineers having a laminated composite product to create: it presents an approach that allows combining to usual morphological design parameters, specific variables that are typically the domain of composite experts, and manufacturing experts. Using an optimization approach based on an evolutionary algorithm coupled to a reduced order analysis, a decision support solution is detailed. The numerical approach allows the engineer to explore interactively design spaces. Our approach is consisting in processing a Knowledge Model having a reduced and separated form [9]. We present a decision support method that allow designers to have, both, a multiscale and a multiphysical view on the laminated structures that they are creating. Two design problems are presented to illustrate the relevance of the approach when designing composite structures: one under a static load and the having a dynamic behavior.

层压复合材料的设计过程面临两个挑战：工程师设计产品及其形态，同时还要设计材料。由于解决方案空间很大，因此设计解决方案的数量可能很大。标准CAE系统（CAD，有限元仿真）无法为设计人员提供有效且交互地探索这些解决方案空间的方法。本文为具有层压复合材料产品的工程师提供了一种可能的程序：它提出了一种方法，可以将通常的形态设计参数，特定变量（通常是复合材料专家和制造专家）组合到一起。使用基于进化算法和降阶分析的优化方法，详细描述了决策支持解决方案。数值方法使工程师可以交互式地探索设计空间。我们的方法包括处理具有简化和分离形式的知识模型[9 ]。我们提出了一种决策支持方法，使设计人员可以对正在创建的叠层结构进行多尺度和多物理视图。提出了两个设计问题来说明该方法在设计复合结构时的相关性：一个在静态载荷下并且具有动态行为。
