This paper presents a perturbation approach for performing sensitivity analysis of
mathematical programming problems. Contrary to standard methods, the active constraints …

Today, in modem structural design the ultimate goal is generally to find the best possible
solution without compromising structural reliability. Toward this aim several reliability-based …

The paper introduces a new approach to composite breakwater design based on minimizing
initial/construction costs subject to yearly failure rate bounds for all failure modes, and …

The paper deals with the timetabling problem of a single-track railway line. To solve the
timetabling problem, we propose a three-stage approach combining several optimization …

In this paper a review of some decomposition techniques previously given by the authors to
solve bi-level problems is presented within a unified formulation, and a new variant is …

The paper examines reliability-based optimization problems formulated as the minimization
of an objective function with reliability constraints that model the requirements for the …

In this paper a brief presentation of the state-of-the-art of reliability-based structural
optimization (RBSO) is given. Special emphasis is put on problems related to application of …

Recent advances in the description of the natural variability of extreme events associated
with ocean climate variables include time-dependent variations within a certain time scale …

Empirical criteria have been used successfully to design filters of most embankment large
dam projects throughout the world. However, these empirical rules are only applicable to a …

This paper presents an integrated approach to sensitivity analysis in some linear and non-
linear programming problems. Closed formulas for the sensitivities of the objective function …
