Design Automation for Site Development

场地开发的设计，如商业建筑或住宅小区，包括规划场地的建筑师、设计结构的多名工程师、场地分级、暴雨排水和公用事业设施的提供，以及必须在发放建筑许可证之前批准设计的市政官员的审查。在目前的设计实践中，对这些个人的工作进行自动化集成的情况很少。因此，设计、审查和重新设计的连续循环既耗时又昂贵，而且产生的是可行的设计，而不是最佳的设计。拟议的研究旨在通过计算机集成其组成部分的活动来实现设计过程的自动化：一个与工地地形模型有关的中央数据库，使用先进的CAD图形系统对工地现有和拟议条件下的可视化，使用有限元方法更准确地计算工地上的暴雨排水，以及一名设计审核员，将城市的条例和良好设计实践的规则整合在一起，以便设计从一开始就沿着可接受的路线进行。美国几个地点的现有场地开发将重新设计，以展示如何通过自动化系统更快、更有效地进行设计。

The design of site developments, such as commercial buildings or residential subdivisions, integrates the work of architects laying out the site, a number of engineers designing the structures, site grading, storm drainage, and provision of utilities, and review by city officials who must approve the design before issuing a building permit. There is very little automated integration of the work of these individuals in current design practice. As a result, the continual cycle of design, review and redesign is time-consuming, expensive, and produces feasible rather than optimal designs. The proposed research aims at automating the design process through computerized integration of its component activities: a centralized database keyed to a model of the site terrain, visualization of the site in its existing and proposed conditions using an advanced CAD graphics system, more accurate computation of storm drainage over the site using the finite element method, and a design checker incorporating the city's ordinances and rules of good design practice so that the design proceeds along acceptable lines from the beginning. Existing site developments at several locations in the U. S. will be redesigned to show how design can be carried out quicker and more effectiveny with an automated system.
