摘要: 为辅助设计人员解决施工设备布置问题,基于遗传算法、虚拟现实技术和三维模型处理技术,提出了类交互式遗传算法。该算法首先执行计算机自动迭代完成的自然阶段,在满足人工参与条件后进入虚拟现实环境,进行人工评价和人工指导变异。通过对比分析表明,该算法能在明显减少用户参与次数的前提下,取得优于交互式遗传算法的解。基于该算法,实现了施工设备布置系统原型,并设计了基于不同技术的不同模块间的数据交互机制。实际应用验证了系统的有效性。

Abstract: To solve the problem of construction facility layout, an Analogous Interactive Genetic Algorithm (AIGA) was presented based on Genetic Algorithm (GA), Virtual Reality (VR) technology and three-dimensional modeling technology. In AIGA, Natural Phase was executed by computer iteration automatically. As qualified conditions were generated, it went into Manual Intervention Phase, in which manual evaluation and manual mutation were executed in VR environment. Comparison between AIGA and Interactive Genetic Algorithm (IGA)proved that AIGA achieved better solutions with less manual intervention. Based on AIGA, a prototype of construction facility layout system was developed. The mechanism for data interaction among five modules based on various technologies was also designed. Users'feedback showed that the proposed system was effect.

Key words: genetic algorithm, virtual reality, three-dimensional modeling, facility layout
