工程设计问题本质上是一个约束满足问题 ,以往的研究集中在约束的求解上 ,忽略了对约束的检测和约束信息的可视化 ,随着工程规模的扩大和领域专家的需要 ,现代 CAD系统与其约束自适应 ,不如把问题检测出来并以可视的方式告知系统设计者 ,于是探讨工程设计中的约束分类、合理组织约束信息的数据结构、研究约束可视化形式方法具有重要的理论意义和实际应用价值。在基于模板思想的基础上 ,这里给出了以模板为载体、多种知识表述方法相结合的约束信息表示形式 ,将层次细节模型运用于工程约束 ,提出了一种约束信息层次可视化模型 ,针对冷冲模设计和反应堆概念设计 ,给出了一个约束可视化原型系统 CCVS。
Engineering design problem is essentially a constraint to meet the problem, the previous study focused on the constraints of the solution, ignoring the constraint detection and constraint information visualization, with the expansion of the project scale and the needs of field experts, modern CAD system and its constraints Adaptive, it is better to detect the problem and inform the system designer in a visual way. Therefore, it is of great theoretical significance and practical value to discuss the classification of constraints in engineering design, reasonably organize the data structure of constraint information, and study the constraint visualization method . Based on the idea of template, a constraint information representation combining template representation and multiple knowledge representation methods is presented here. The hierarchical detail model is applied to engineering constraints, and a hierarchical information visualization model is proposed. Cold Die Design and Reactor Concept Design, a constrained visual prototype system CCVS is presented.
