Methods for Designing Hydraulic Aquifer Remediation Techniques
This paper reports on recent research to develop methods for accommodating uncertainty in designing hydraulic remediation systems for contaminated aquifers. The methods rely respectively...

Water Supply Uncertainties with Federal Permitting
Providing water in a semiarid region has historically been one of the most important responsibilities of government. This task was made more difficult by the uncertainties involved with...

Reliability in Rock Engineering
This paper reviews approaches to reliability in rock engineering through a survey of methods developed at MIT. Since these methods are intended to be applied in engineering decisions,...

Loading Uncertainties in Extreme Waves
Uncertainties associated with extreme base shear forces and extreme overturning moments are estimated for an idealized eight-legged jacket platform. The structure is assumed to respond...

Multi-Hazard Risk Assessment of an Offshore Structure
This paper develops and illustrates a methodology for multi-hazard modal risk assessment. The case study involves assessing risk to an offshore structure in a load environment consisting...

Practical Aspects of Structural Control
Several problems in the practical implementation of structural control are discussed herein. These problems include the prediction of the actual behavior of existing structures, mathematical...

Failure Prediction for Non-Linear Structural Systems
A method is described that makes failure predictions for structures which are complex, nonlinear and expensive to evaluate on a computer. The method makes use of a non-linear response...

Potential Applicability of Mathematical Statistics in Stochastic Modelling of Failure Phenomena
Failure phenomena should be investigated clearly with a good understanding of engineering uncertainties associated with strength of the material as well as randomly applied load. In this...

Uncertainty, Risk, Variability: Design Concerns

U. S. Nuclear Regulatory Commission's High-Level Waste Repository Licensing Program and Regulatory Strategy
The U. S. Nuclear Regulatory Commission (NRC) High-Level Waste Repository Licensing Program during the pre-licence application phase consists of activities in the following four areas:...

Analysis and Evaluation of Regulatory Uncertainties in 10 CFR 60 Subparts B and E
An attribute analysis scheme is presented for for prioritizing the resolution of regulatory uncertainties. Attributes are presented which assist in identifying the importance, need for...

Transportation Cask Life Cycle Cost Uncertainty Analysis
This paper demonstrates an uncertainty analysis methodology using random sampling. This methodology has been applied to a nuclear waste transportation code, and several transportation...

Probabilistic Analysis of Maintenance Options
Maintenance usually means service disruption, repair cost and loss of production. This is especially true for structures or components which provide basic infrastructure services, such...

Tutorial: Fuzzy Set Theory in Water Resources Systems
Principles of using fuzzy set theory (FST) to describe imprecision (or vagueness) in water resources systems are provided. The main tool of FST, the membership function, measures the degree...

Risk Management for Groundwater Contamination: Fuzzy Set Approach
A methodology is developed for health risk management under uncertainty, using fuzzy sets. Groundwater nitrate contamination illustrates the methodology. A risk management framework is...

Bayesian Decision Theory and Fuzzy Sets Theory in Systems Operation
Operation of Water Resources Systems involves complex set of human decision. Many of the parameters involved in systems operations are random functions of time. Sometimes, the data needed...

Analysis of Uncertainty in Ground-Water Quality Monitoring Network Design
The paper reviews alternative approaches to ground-water quality monitoring network design. Four general approaches to network design are reviewed: (1) hydrogeologic, (2) simulation, (3)...

First-Order Uncertainty Analysis of Reactors in Series

Modeling Exposure to Volatile Organic Compounds (VOCs) from Showers: An Uncertainty Analysis

A Reservoir Yield Evaluation in an Arid Climate
Yield calculations rarely can be more accurate than roughly plus or minus twenty percent. The same uncertainty is dramatically greater in arid climates where the average annual runoff...
