Designing in Three Dimensions for Manufacturing Facilities
Du Pont Engineering is using Three-Dimensional Design for the design of our manufacturing facilities. Our 3D design system was used on several projects in 1992, and full implementation...
Object Oriented Modeling of Structural Systems
Computational engineering in structural design is no longer restricted to numerical approaches. Increasingly, also non-numerical, in particular, cognitive problems can be implemented into...
Object-Oriented Modelling for Concrete Structures
The use of computers for the design process has reached wide acceptance. The use is developed in several fields such as CAD, CAM or programs for design of structural elements. Recent work...
Object-Oriented Data Exchange for the Integration of Design Processes in Structural Engineering
The computer integration of tasks, activities, tools, user and data exchange interfaces, management of knowledge etc. requires a new approach by object-oriented modeling in civil engineering....
A Model to Quantify Work Space Availability for Space?Contrained Scheduling Within a CAD Environment
In any given process work area, a task or activity requires a specific amount of space for its execution. This required space must be accommodate by the physical space of the work area...
A CAD-Based Construction Simulation Tool Kit for Construction Planning
Current planning and scheduling techniques place considerable reliance on the planners judgement, imagination and intuition. The result of such techniques is typically lengthy text reports...

The Automation of Freeway Ramp Junctions Analysis
Congestion on urban freeways has been steadily increasing. In contrast, capacity expansion, by means of constructing new roadways, has not kept pace with the growth in demand. The primary...
Object Based Visualization of Physical Behavior
In engineering science, the physical behavior of solids, fluids, gases and multiphase systems is analyzed with computational models. Numerical methods form the basis of the computational...
An Object Oriented Approach to Computing with Structural Components
The structural analysis process can be modeled in two separate steps: definition of structural systems and analysis of a discrete numerical model; the transmission between these two models...
Computer-Aided Decision Model for Selecting a Contractual System
An owner of a construction project often faces the problem of selecting a contractual arrangement. The process of selecting a contractual system depends on the owner's preferred risk sharing...
