Integrated Data Exchange and Concurrent Designs for Engineered Facilities

建筑-工程-建筑行业是高度分散的，既有垂直的(在项目阶段之间，例如规划、设计和施工)，也有水平的(在给定项目阶段的专家之间，例如设计)。该行业需要一个集成的计算环境，该环境将支持并行设计，具有快速的数据交换和强大的更改管理能力。本研究项目的主要贡献是：(1)动态地翻译和交流项目数据，克服逻辑障碍(重叠数据的不同视图)和物理障碍(数据分布)；以及(2)在并行设计过程中有效地检测、分析和管理更改。这些贡献在集成了CAD、绘图、分析和模拟系统以及关系数据库和面向对象数据库的原型软件中得到了展示。第一个软件组件是一套集成的面向对象的多机器实用程序，以提供快速、灵活、智能的数据转换和传输。

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.
