Environmental impact assessment studies cover a number of activities for: data collection, data analysis, numerical modeling, system monitoring, and regulation compliance. The diversified...

Intelligent Design and Remediation of Shallow Landfill Burial Systems
The SLEUTH (Shallow Landfill Evaluation Using Transport and Hydrology) prototype decision support system (DSS) has been developed for design and remediation of shallow landfill burial...

Representing Design Cases Based on Methods
This paper discusses an approach to representing design cases using the methods used in solving specific design problems. This differs from the conventional representation of design cases...

Representation of Case Memory for Structural Design
One of the major issues to be addressed in the application of case-based reasoning to structural design is the representation of design projects in case memory. The content of the information...

Advances and Challenges in Case Based Design
The application of the case-based design (CBD) method to preliminary building design provides an opportunity to overcome problems associated with traditional computer-based design methods....

Modeling to Generate Alternatives in Discrete Structural Optimization
Structural design, like other complex decision problems, involves many trade-offs among competing criteria. While mathematical programming models are increasingly realistic, there are...

Multicriteria Optimization in Engineering Design
An engineering design optimization problem can be formulated as a search of the solution space for which the relationships among various groups of attributes are given. The search can...

Representation of Vertical Constraints Knowledge for Scheduling Multi-Story Projects
Multi-story projects are characterized by many repetitive units or typical floors that involve identical activities repeated consecutively from one floor to the next. Horizontal logic...

Selecting Precast Concrete Building Systems
The development of an integrated computer system to assist in the selection of precast concrete (PC) building systems is described. StructNet, a neural network program, identifies possible...

The MOUSE Uncertainty Analysis System
MOUSE (Modular Oriented Uncertainty SystEm) is a Monte Carlo based simulation system designed to deal with the problem of uncertainties in Environmental engineering calculations, such...

A Decision Support System for Nonpoint Source Pollution Management Using a Distributed Model-GIS-DBMS Linkage
Methods were developed for directly linking the distributed parameter model, AGNPS with a GIS and a relational database management system (RDBMS) to investigate a nonpoint source pollution...

Selection of Earth Retention Systems Using Expert System
The development of the selection module in a knowledge-based expert system REtaining STructure EXpert (RESTEX) for automated selection, design and analysis of earth retention systems is...

Quality Management of Earthwork Using Knowledge-based Systems
Earthwork is an integral part of many construction projects. It involves cleaning of the site, loading and spreading of soil, and soil compaction and leveling. Heterogeneous orientation...

Scaling Up is Hard to Do: Experiences in Preparing a Case-Based Design Aid Prototype for Field Trial
We seek to improve the conceptual design process for complex artifacts such as buildings by offering designers access, through an on-line hypermedia library, to documentation and evaluations...

Case-Based Design in the SEED System
We present the requirements for case-based design in a software environment to support the early phases in building design and outline an approach to satisfy them. We briefly discuss implementation...
