用户添加的约束和系统自动识别的约束能动态添加到有向约束图中，并支援任意图形块的选择重复。 - The paper constructs an imaging demand constraints model , on the base of which multi - objective evolutionary algorithm is applied to implement the scheme scheduling of imaging satellites
对此,本文构建了一种成像需求约束图模型,并以此模型为基础,应用多目标进化算法实现成像卫星的计划编制。 - Modeling in conceptual design is a key technology in cacd system . considering the characteristics of conceptual design and the feature classification of vp , this paper presents a novel virtual prototype - based product model , v - desmodel . v - desmodel introduces virtual feature concept in product ' s view models , and employs expandable 3d entity - constraint graph to describe the constraints between design objects
概念设计建模一直是计算机辅助概念设计系统的核心与关键技术，本文在分析虚拟原型的特征分类以及概念设计过程特点的基础上，提出一种基于虚拟原型的概念设计描述模型v - desmodel ，其核心特点是采用产品视图模型描述设计对象，将虚拟特征概念融入视图模型中，并采用可扩展“三维实体?约束图”描述设计对象之间的约束关系。 - At first every method of constraint solving is presented in this paper . through comparing the advantages and disadvantages of one method with another the method of constraint solving based geometrical constraint graph in which geometrical constraint system is expressed by graph , and which can deal with over - constraints and down - constraints is proposed
本文首先总结了二维参数化设计中的各种约束求解方法，并权衡每种约束求解方法的利弊，提出了基于几何约束图的约束求解方法，此方法是用图来表示几何约束系统，能够有效地处理欠约束和过约束的情况。 - Inplementation of the above in a prototype system named cacds in the first part of the thesis the general contents of computer aieded conceptual design and its status quo is inrtoduced . detailed definition of component feature model ( cfm ) and its relative operations are described in chapter 2 . in chapter 3 we invited " " component feature space " as the key element in layout design , and a new constraints driven layout creation methodology , which is based on graph theory and human - computer cooperation , is discussed
本文以国家863计划项目? ? “面向产品创新的计算机辅助概念设计技术的研究”为背景，以产品信息模型和求解方法为着眼点展开研究，主要贡献在于： ( 1 )拓展了组件特征模型，使其可以支持概念早期设计阶段的信息表达和推理； ( 2 )提出了一种基于约束驱动，结合约束图与人机合作的布局设计求解方法； ( 3 )在cacd原型系统中，对上述两点进行了实践。
