Evaluation of Software for Analysis and Design of Reinforced Concrete Structures
A study to verify the accuracy of two structural analysis and concrete design programs and to evaluate their functionality was conducted. The evaluation was based on a comparison of results...

Strategic Ship Routing Impacts of Temporal Coverage with Real-time Satellite Altimeter-Based Current Information
We investigate strategic ship routing impacts of temporal coverage with real-time satellite altimeter-based current information. We sample underlying daily `true' current patterns along...

Metamodeling Approach for Approximating the Operating Characteristics of Series of G/G/1 Queues on Congested Waterways
A simulation model representing waterway networks with queues at locks has been developed and validated. Functions developed from queueing theory were formulated to describe the operating...

Computer Automation and Project Organizational Impact: A Conceptual Model
This paper presents a framework to effectively model the impact of change in the level of computerization on project organizations. A key focus is the changing relationships between project...

Personal Computer Model to Evaluate Performance of Construction Systems/Services
Worldwide competition has finally impacted the construction industry and facility managers. As manufacturers become more competitive, the cost of doing business becomes more critical....

A Goal Driven Approach to Discrete Event Simulation
Discrete event simulation is getting more attention as a tool for allocating construction resources. However, its usage is limited because it requires intensive knowledge in conducting...

A New Automated System for Decision Support in the Construction Industry
This paper describes a collaborative project to research and develop a computer based decision support system for the construction industry. The system is intended primarily for use during...

Using CADD Application to Support Construction Activities
This paper discusses how electronic CADD submittals from designers can be transformed into a format appropriate for construction planning and management. Currently, design drawings are...

3D CAD Modeling and Graphical Simulation of Mobile Cranes
This paper describes the research performed to lay a foundation for developing a graphical simulation system which can be used in the planning of heavy lifts using mobile cranes. Mobile...

CAD-Based Intelligent Drawings: An Automated Quality Control Approach to Land Development
Computer-Aided Design (CAD) is currently used within every discipline of civil engineering. Initially, CAD was employed solely as a drawing/drafting tool. Current CAD packages, in conjunction...
