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...

A Work Packaging Process Model for Petrochemical Plant Piping Construction
This paper presents a model for the current work packaging process for petrochemical plant piping construction. The basic foundation of the model is formed by identifying major decision...

Linear Scheduling: A Practical Implementation
This paper describes the features and use of a family of planning structures that provides the basis for a superset of the traditional critical path method which includes linear scheduling....

ICPS: Integrated Construction Planning System by Object-Oriented Planning Models
Knowledge processing for integrated building system planning and construction system planning poses challenging problems to integrate design and construction process efficiently. While...

Floodplain Delineation Using TINS
Triangulated Irregular Networks (TINs) are becoming an increasingly common tool for modeling terrain surfaces on the computer. They are formed by the triangulation of scattered xyz data...

Application of Computer Simulation in the Research of Rail Structure Vibration Reduction
The wheel/rail system is described here as a random vibration system, and the state variables are expressed with quadratic evaluation function. The passive control problem of the random...

Interdisciplinary Communication of Design Critique in the Conceptual Design Stage

Agent-Based Technology for Facility Design Software Integration
The application of a novel technology called Agent-Based Software Engineering to facility design software integration is presented. The technology is founded on the notion of design agents...

Dynamic Response of Bridges Under Traffic Loads
Numerous analytical and experimental investigations have been carried out in the past to study the complex dynamic problem of the response of a bridge deck to a moving vehicle. However,...

Object-Oriented Finite Element Modeling
The present paper studies the suitability of object-oriented modeling strategies for problems of structural mechanics. After a general discussion of the topic, special emphasis is put...

Simulation of ATIS Strategies to Mitigate Special Event Congestion
This research extends the performance and application of DYNASMART, a dynamic traffic simulation model which incorporates the three elements necessary for modeling traffic flow under information:...

Interactive Simulation for Modeling Dynamic Driver Behavior in Response to ATIS
It has been contended that in-laboratory experimentation with interactive microcomputer simulation can substitute for the lack of real-world applications and provide a useful approach...

Algorithms for Efficient Real-time Traffic Assignment
Fast algorithms are essential to accomplish real-time traffic assignment for optimal routing or traffic prediction under ATMS/ATIS. User-equilibrium and system-optimal traffic assignment...

Modeling and Analysis of Shafts and Tunnels for the SSC
A brief overview of the Superconducting Super Collider Project (SSC) is presented followed by a discussion of the 3D modeling and finite element analysis of tunnels and shafts. The sequential...

Developing an Integrated Database Structure for the Lifecycle of Precast Concrete Projects
This paper presents an integrated database structure for the storage and retrieval of information during the planning, design, manufacturing and construction of a structural precast concrete...

Modeling Facility Engineering Processes & Data Using the P-C Approach
A facility engineering process typically involves participants from different disciplines, several life-cycle phases, and many computer applications. In this paper, we propose the Primitive-Composite...

An Automated Database System for Construction Bidding
A number of probability-based bidding models have been developed to assist a contractor in preparing bids that improve chances of winning over the competition. Models based on utility...

Qualitative Formulation of Load Paths Through a Functional Description of Structures
The past few decades have seen major advances in computer tools to analyze complex structures and loadings. For the most part, these programs have focused on two areas - A, programs for...

Crack and Contact Problems in Masonry Arch Bridges
A two-dimensional finite element program has been developed to predict the load carrying capacity of masonry arch bridges with different structural defects such as missing bricks and tangential...

Analysis of Sequential Route Choice Under ATIS
An experiment to collect sequential route choice data under the influence of an Advanced Traveller Information System (ATIS) was performed using a PC-based interactive simulation. The...
