Genetic Algorithm for Solving Site Layout Problem with Unequal-Size and Constrained Facilities
(American Society of Civil Engineers, 2002)This paper presents an investigation of the applicability of a genetic approach for solving the construction site layout problem. This problem involves coordinating the use of limited site space to accommodate temporary ... -
Design of Distributed Interactive Online Geographic Information System Viewer using Wavelets
(American Society of Civil Engineers, 2002)The purpose of this work is to develop a distributed interactive online geographic information system (DIO-GIS) viewer using wavelet theory. Wavelet analysis is a new mathematical tool that transforms information into a ... -
Production Scheduling for Precast Plants using a Flow Shop Sequencing Model
(American Society of Civil Engineers, 2002)There are two alternatives for production organization in precast factories—namely, the comprehensive method and the specialized method. Production scheduling under the specialized alternative has been found to be a difficult ... -
Neural Network Embedded Monte Carlo Approach for Water Quality Modeling under Input Information Uncertainty
(American Society of Civil Engineers, 2002)This paper proposes a neural network embedded Monte Carlo (NNMC) approach to account for uncertainty in water quality modeling. The framework of the proposed method has three major parts: a numerical water quality model, ... -
Clustering Technique for Evaluating and Validating Neural Network Performance
(American Society of Civil Engineers, 2002)Data used for training and testing a neural network (NN) are often collected from limited sample projects. They may constitute clusters instead of being evenly distributed over the entire space. This paper first studies ... -
Iconic Animation for Activity-based Construction Simulation
(American Society of Civil Engineers, 2002)This paper discusses the development of an animation tool for the activity-based construction (ABC) modeling and simulation system. The tool uses an activity-based network diagram, i.e., ABC simulation model, as the animation ... -
Object-Oriented Framework for Genetic Algorithms with Application to Space Truss Optimization
(American Society of Civil Engineers, 2002)Genetic algorithms have been shown to be very effective optimization tools for a number of engineering problems. Since the genetic processes typically operate independent of the actual problem, a core genetic algorithm ... -
Method for Conceptual Design Applied to Office Buildings
(American Society of Civil Engineers, 2002)The paper presents a computer-based method for the multicriteria conceptual design of engineered artifacts. The proposed method involves genetic-based stochastic search, Pareto optimization, and color-filtered graphics. A ... -
Formalization and Automation of Time-Space Conflict Analysis
(American Society of Civil Engineers, 2002)With increasing pressure for shorter delivery schedules, space is a critical resource at construction sites. Current industry practice lacks a formalized approach or tool to help project managers analyze spatial conflicts ... -
Nonlinear Models for Predicting Hoisting Times of Tower Cranes
(American Society of Civil Engineers, 2002)Accuracy in estimating activity duration is one of the key prerequisites for successful construction planning. Efficient material transportation plays an important role in reducing costs and time. Time measurement and ... -
Neural Network Forecast Model in Deep Excavation
(American Society of Civil Engineers, 2002)Diaphragm wall deflection is an important field measurement in deep excavation. The monitoring data are applied to evaluate the construction performance to avoid a supporting system failure or damages incurred to adjacent ... -
Multiple Device Collaborative and Real Time Analysis System for Project Management in Civil Engineering
(American Society of Civil Engineers, 2002)Complexity in civil engineering projects has increased over the years, which has led to an increase in the number of organizations involved in those projects. In today’s environment, these organizations operate in different ... -
Data Preparation Process for Construction Knowledge Generation through Knowledge Discovery in Databases
(American Society of Civil Engineers, 2002)As the construction industry is adapting to new computer technologies in terms of hardware and software, computerized construction data are becoming increasingly available. The explosive growth of many business, government, ... -
Tool for Rural and Statewide Multimodal Transportation Planning
(American Society of Civil Engineers, 2001)The Georgia Department of Transportation's Multi-modal Transportation Planning Tool (MTPT) facilitates multimodal planning in rural areas. Using open databases that are available agencywide, the tool can aid in the analysis ... -
