*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)...*
