Aversion to Epistemic Uncertainties in Rational Decision Making: Effects on Engineering Risk Management
When faced with epistemic uncertainties in a decision problem, subjective expected-utility theory (SEU) implies that the only relevant characteristic of these uncertainties is the mean...
System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...
The Role of Risk Analysis in Feasibility Studies of Water Resources Projects
Many parameters involved in feasibility studies of water resources projects are inherently uncertain. Projections of these parameters based upon extension of past trends can be quite inaccurate....
Optimal Allocation of Resources in Repair and Maintenance of Bridge Structures
The structural design process, examined in its entirety (and taking into account the uncertainty and randomness that characterize the governing parameters) is a decisional process, involving...
Implementing Uncertainty Treatment in AI Development Environment
The seismic vulnerability of existing masonry buildings is investigated by an expert system prototype. Field inspectors have to provide answers which can be of a Boolean, fuzzy or probabilistic...

A Coordinate Reduction Technique With Mass Correction for Dynamic Analysis of Structural Systems
A more accurate technique which can be applied for reducing the order of system matrices when employing the finite element method (FEM) is presented. Unlike traditional reduction techniques,...
Controlled Braking on Uneven Roads
The braking process of a passenger car may be influenced by a large number of variables relating to driver, vehicle, brake system, tire-road interaction and ambient conditions. Because...
Asymptotic Importance Sampling
One of the main issues in reliability analysis is the accurate and efficient calculation of the multivariate reliability integral. The Asymptotic Importance Sampling Technique (AIS) selects...
Sampling Techniques for Time-Variant Reliability Problems
Time-variant structural reliability problems arise when the structural resistance may change with time (such as in structural deterioration) or when the system is acted upon by two or...
A Unified Simulation Approach to Structural System Reliability Analysis
To determine accurate estimates for the system reliability of large complex structures requires considerable computation; unless the problem is assessed in an efficient manner the analysis...
Use of Importance Sampling Constraints in System Optimization
An important application of system reliability analysis is to incorporate overall system risk as a constraint in a structural optimization. The paper describes the use of Monte Carlo Importance...
