The architecture-engineering-construction industry is highly fragmented, both vertically (between project phases, e.g., planning, design, and construction) and horizontally (between specialists at a given project phase, e.g., design). The industry needs an integrated computing environment that will support concurrent design with fast data exchange and powerful change management capabilities. The long-term potential benefits are improved designs, reduced construction time, fewer design errors and omissions, minimization of costly rework, and better life-cycle facility management. The key contributions of this research project are methods to (1) translate and communicate project data dynamically, overcoming both logical barriers (differing views of overlapping data) and physical barriers (data distribution); and (2) detect, analyze, and manage changes efficiently during concurrent design processes. These contributions are demonstrated in prototype software that integrates systems for CAD, drafting, analysis, and simulation along with relational and object-oriented databases. The first software component is an integrated set of object-oriented, multi-machine utilities to provide fast, flexible, intelligent data translation and transfer. The second component is a set of constraint handling and change management utilities that will support declarative definition of data dependencies, constraints, and conflict resolution strategies. The project will take advantage of industry links through Stanford University's Center for Integrated Facility Engineering to develop a test bed of industrial-strength databases to demonstrate the software.

建筑-工程-建筑行业高度重视 纵向（在项目阶段之间，例如， 规划、设计和施工）和横向（ 特定项目阶段的专家，例如，设计）。 的 工业需要一个集成的计算环境， 支持并行设计，数据交换速度快，功能强大 变革管理能力。 长期潜在利益 改进设计，缩短施工时间，减少设计 错误和遗漏，最大限度地减少昂贵的返工， 生命周期设施管理。 这方面的主要贡献 研究项目的方法是（1）翻译和交流 动态项目数据，克服两个逻辑障碍 （对重叠数据的不同看法）和物理障碍（数据 分发）;以及（2）检测、分析和管理变更 在并行设计过程中高效地进行。 这些 在原型软件中展示了这些贡献， 集成CAD、绘图、分析和模拟系统 沿着关系数据库和面向对象数据库。 第一 软件构件是面向对象集成集， 多机公用事业提供快速，灵活，智能 数据转换和传输。 第二个组成部分是一套 约束处理和变更管理实用程序， 支持数据依赖关系、约束 和解决冲突的策略。 该项目将需要 通过斯坦福大学中心的产业联系优势 为综合设施工程开发一个试验台， 工业强度的数据库来演示软件。
