大跨空间结构智能选型设计初探

Intelligent selection of long-span spatial structural designs

大跨空间结构的选型设计属于概念设计范畴,包括方案生成、方案评价和方案决策三个关键设计阶段。大跨空间结构的智能选型设计包括三个方面的研究内容:选型方案的智能生成,选型方案的智能评价,选型方案的智能决策。方案生成过程中专家的思维方式主要包括逻辑思维、形象思维和创造性思维,方案评价属于多人、多层次、多目标的综合评价问题,方案决策包括选型设计过程决策、方案可接受性决策、方案再设计决策和方案优选决策。提出了大跨空间结构选型方案智能生成的协同推理模型,方案智能评价的因素体系模型以及系统的软件实现形式和体系组成形式。

The intelligent selection of long-span spatial structural design consists of generation and evaluation of and decision-making on structural design schemes,and it there fore covers intellingent generation and evaluation of and decision-making on structural styles.The way of thinking of experts during scheme generation generally take the form of thinking in both logic and image.Scheme evalua-tion is a multi-person,multi-stage and multi-objective comprehensive evaluation process.The deci-sion-making process includes selection of structural styles,decision on acceptability of design schemes re-desiogn of schemes and selection of optimal schemes.A well-coordinated reasoning model for intel-ligent generation of structural design schemes together with factors used for evaluating structural de-signs is put forward and the realization software and its system architecture for the intelligent opti-mization and selection of structural styles are advanced as well.
