Constraint Management for Concurrent Design and Construction Using an Object-Oriented Project Model
To realize a richer communication among multiple disciplines participants of A/E/C project, an object-oriented product or project model is useful and powerful. especially sharing and maintaining...
Creative Engineering Design Using Analogy
Designs in different domains vary in structure, performance and in many other aspects. However, their design purposes can be achieved in a limited number of ways. In this paper, we classify...
A Shape Annealing Approach to Creative Design of Structures
This paper shows how shape grammars can be used to model structural engineering problems. The shape annealing algorithm is then used to synthesize component topologies by bringing analysis...
Optimal Processor Mapping for Massively Parallel Finite Element Computations
The exploitation of massively parallel computer for finite element analysis requires efficient usage of processors as well fast speed. For example, the efficiency of a parallel matrix...
Integrating Database and Geometric Modeling Technologies to Manage Facility Information
Existing engineering data models provide various means of representing, organizing and linking information about constructed facilities in a computer-integrated environment. However, they...
Resource Constrained Time-Space Scheduling Model
This study aims to develop a resource constrained time-space scheduling model, mainly aiming application to pipeline laying world for gas supply under roads in urban area. This model can...
TRACS: A Tool for Track Infrastructure Management
TRACS (Total Right-of-way Analysis and Costing system) combines engineering models with life-cycle costing techniques to estimate track maintenance and renewal costs as a function of track...
Tie Model: A Crosstie Replacement Planning and Costing Model
The Tie Model described in this paper is a maintenance planning and life-cycle costing model for wood crossties. The model includes a number of different failure modules to predict crosstie...
Inspection and M&R Decisions for Infrastructure
This paper reviews different possible mathematical formulations for a joint inspection and M&R decision-making model, having various levels of restriction and computational complexity....
Pavement Network Level Management Using Micro PAVER
This paper presents pavement network level management using Micro PAVER with emphasis on pavement condition prediction modeling and annual and long range work planning....
An Overview of Markovian Models for Bridge Management Systems
The typical infrastructure maintenance decision-making environment involves multiples objectives, uncertainty, and dynamics of the most commonly used infrastructure models, which captures...
Deterioration Models for Highway Bridges
Infrastructure management, especially in case of highway bridges, need a realistic and effective deterioration model in order to provide information on the present and future condition...
Identifying a New Role of the Future Planner
It has been amply demonstrated over the last three decades that public planning is subject to great uncertainties, both in dealing with new technologies as well as in dealing with fuzzy...
Projecting Land Use/Transportation Interactions
The inherent uncertainty in forecasting the interaction between transportation capacity and induced development has resulted in insufficient analysis of this dynamic in the transportation...
Use of Fuzzy Theory for Dealing with Uncertainty: Evaluating Alternatives Under Uncertainty
A method to deal with uncertainty which is associated with vagueness and ambiguity is presented. Fuzzy sets are introduced to account for vagueness in expression and fuzzy measure is introduced...
Evaluation of HSGT Systems Under Uncertainty
The basic themes of this paper are two-fold. First we investigate what planning style is likely to be most suited for planning an HSGT system, dependent on three interdependent key variables:...
Medium Classic Rail Traffic: How to Forecast the New High Speed Rail Traffic
This paper describes the current situation of the transport flows by modes in the international relations between Spain and the rest of Europe. Explains the geographic zoning adopted for...
Intercity Travel Demand Modeling and Forecasting for High Speed Rail Service in the Quebec-Ontario Corridor
This paper describes the application of intercity travel demand models and preparation of ridership and revenue forecasts for the Ontario/Quebec Rapid Train Task Force in 1990. The development...
Intercity Travel Demand Forecasting for the Windsor-Quebec City Corridor
Travel demand forecasts were required for the 600-mile-long Quebec City - Windsor Canada Corridor to test alternative rail systems including high speed rail. The approach involved application...
Assumptions Behind Ridership Forecasts for High Speed Ground Transportation Systems and Their Validity: The California-Nevada Case Study
Accurate prediction of ridership is one of the key elements for approval of any transit project and eventually for survival after the system begins operation. This is particularly true...
